Andrew Allcock reviews some of the more notable and relevant-to-the-UK product unveilings of the recent IMTS exhibition, held in Chicago from September 13-18, America's biennial manufacturing technology show [extended version]

The company with the greatest number of innovations appeared to be MAG (0121 306 5600), the company that is home to the numerous famous brands, such as Cincinnati, Cross Hüller, Fadal, Giddings & Lewis, Hüller Hille, Witzig & Frank, Hessapp, Ex-Cell-O, Honsberg and Boehringer. The company unveiled its HyperMach GTi series 5-axis titanium aerospace profiler, intended for efficient processing of large parts, such as spars, bulkheads and door edge frames, or nested part groups. The new HyperMach H4000 GTi was shown, with hard-metal cutting using a new 5-axis HSK100A 6,000 rpm/850 Nm high torque geared spindle. Capacities range from 2 by 4 m to 2 by 8 m. Image: The HyperMach GTi is a machine targeted at titanium machining Staying with titanium machining and MAG's Max-Flute high performance end mills enable machining of internal structures in titanium, Inconel and stainless steel components at removal rates of up to 130 cm3/min using only 34 Nm of torque. Used in conjunction with Surfcam's TrueMill software (www.surfware.com), the 16-flute, unequal pitch Max-Flute end mills maintain a constant angle of engagement, making the radial cuts more consistent throughout the cutter path, increasing material removal rates and decreasing cycle times, while extending tool life. "The current approach to high-speed machining involves taking very light cuts," said Dan Cooper, CYCLO CUT product manager for MAG Regional Services. "The Max-Flute/TrueMill approach enables the machine to make heavier cuts at high speeds, and by using the maximum flute density available, maximum feed rates are achievable." MAG also exhibited a breakthrough in cryogenic machining, demonstrating a new US Navy-sponsored development that utilises a unique through-spindle, through-tool cooling system employing liquid nitrogen. "We are still in development, but have achieved 60 per cent speed increases in milling CGI with carbide, and up to four times using PCD (polycrystalline diamond) tooling. With the addition of MQL, we tripled speeds with carbide, but showed no further benefit to the fourfold increase with PCD," said MAG vice president of engineering Doug Watts. "These tests focused on metal removal increases, while keeping tool life equal to what would be achieved with conventional coolants. Early results indicate this technology could dramatically improve the lifecycle cost model for machining in a 'hard-metal' environment by reducing the required number of machines and associated plant infrastructure, or possibly increasing tool life beyond anything thought possible today. "We are actively seeking partners to participate in further development, and hope to commercialise the technology next year," Mr Watts concluded. (See box item for other MAG product announcements in brief.) WHAT A BLAST Associated with coolant, but a little less exotic and more immediately available is Kennametal's Beyond BLAST, an extension to its Beyond insert range. By channelling coolant through the insert, at the interface of the cutter and insert, Beyond BLAST delivers coolant directly where the tool cuts the material, ensuring efficient coolant delivery, heat transfer, and lubrication. "In tests involving titanium turning, Beyond BLAST inserts at 100 psi were showing 75 per cent improvement in tool life over the same inserts with flood coolant at 100 psi," says senior product manager Osny Fabricio. "In a different test to evaluate the influence of coolant pressure, tool life for Beyond BLAST at 100 psi was nearly that of identical insert geometries at 1,000 psi – higher cutting conditions or longer tool life at significantly lower cost." In milling tests involving titanium (TiAl6V4), the results are even more spectacular, with tool life increases of 250 to 300 per cent, depending on the insert geometry and cutting conditions. "With Beyond BLAST, the result gives Kennametal a new and improved turning and milling product portfolio and it's very easy for metalworking companies to upgrade their manufacturing processes," says Mr Fabricio. "It's a plug and play solution." Image: By channelling coolant through the insert, at the interface of the cutter and insert, Beyond BLAST delivers coolant directly where the tool cuts the material Staying with tooling and MAPAL (01788 574700) had a number of innovations. These included new drills for cost-effective machining of work pieces of lightweight construction materials such as CFRP, aluminium, titanium or composite metal materials. These are the new spiral WDrill for all, the HPC-Drill (for titanium), and the UD- and MD-Composite Drill. Another drill, the MAPAL MEGA-Drill-180° is a solid carbide drill for bores with flat bottoms. Additionally, the company has developed a new application-specific solid carbide milling cutter product range. Under the designation OptiMill, the standard program includes universal end milling cutters and milling cutter types designed specifically for special applications for machining steel, cast iron, aluminium and stainless steel, as well as for hard milling. Finally, the MAPAL Tritan-Drill is a three-bladed drill for maximum centring precision. Tool presetter expert Zoller (Fenn Tool, 01376 347566) introduced its POM technology – process-oriented-measuring – specifically targeted at the tool manufacturing industry, as well as grinding and sharpening companies. The machines are equipped with special functionalities required for the production of milling cutters or drills and can be used directly next to the CNC machine. Developed for sample inspection and quick tool checks, POM machines are deliberately built small and compact and can thus easily fit in any production environment. Image: Zoller POM machines are deliberately built small and compact Another development is Zoller's Smile EDM, which not only measures cutting tools but also electrodes. The company's CAZ software enables the set-up of measuring sequences, based on a 3D drawing of a tool. NEW PRECISION BENCHMARK Hardinge (0116 286 9900) launched a turning machine that, it says, sets a new benchmark in high precision, the T-42 turning centre. The 42 mm bar capacity unit offers axis repeatability within 0.76 micron, a roundness value of 0.25 micron, overall accuracies within 3 microns and a low-micro surface finish within 0.15 micro-metres (see Machinery, September 2010, page 00). In addition, the company, in co-operation with the TRUEMill Division of CADCAM company Surfware, demonstrated "unsurpassed material removal rates", machining 4140 alloy steel on the new Bridgeport GX-1000 OSP-P200M vertical machining centre, which is fitted with Okuma THINC-OSP control. Using a ½ inch diameter end mill cutting at 1 inch depth at a feed of 475 inches per minute (12 m/min), a peak material removal rate of 18.6 in3/min (305 cm3/min). Mori Seiki and DMG shared a stand, with Mori Seiki launching 10 new models, including the NHX4000 horizontal machining centre, NLX2500/700 lathe and NVX5000 vertical machining centre. The NLX2500/700 demonstrates the continuous improvement of Mori Seiki's established lathe series at an unprecedented value, for example (see box item 2, below for more detail). Kitamura Machinery (Leader CNC, 024 7635 3874) revealed its Mycenter-HX400iSII space-saving horizontal machining centre with 4th axis. It comes with a 13 kW, 20,000 rpm spindle and can tackle parts of 630 by 740 mm and weighing 350 kg. Up to 290 tools and 21 pallets can be installed in field to increase production capabilities as needs change. A 5th axis retrofit is available as is optional 5-axis capability. Hermle (Geo Kingsbury, 023 9258 0371) was highlighting new MT (Mill/Turn) concept to be available on the C 42 U, C 50 U and C 60 U universal machining centres by means of a video presentation. The MT series offers rotational speeds of 800, 500 and 400 rpm in the C 42 U, C 50 U and C 60 U series, respectively. Image: Hermle's new mill-turn concept made its debut at IMTS GF AgieCharmilles (024 7653 8666) partnered with EOS (01926 62310) and demonstrated a nearly automatic process chain for creating injection and blow mould tooling having conformal cooling channels. The breakthrough manufacturing process chain is one that runs virtually unbroken from design to finished product. During the demonstration, an EOSINT M 270 direct metal laser-sintering (DMLS) system created a steel mould for a plastic, blow-moulded golf ball, complete with conformal cooling channels and the fixturing needed for all successive stages of machining. This was then moved through a secondary process chain that included a GF AgieCharmilles HSM 400U LP high speed milling machine, an FO 350MS die sinking EDM, and a Cut20P wire EDM. The wire EDM cut off the fixturing, the HSM 400ULP cut the parting lines for a flash-free (no leakage) surface, leaving the mould ready for production use. The two new versatile entry-level Sodick (Sodi-Tech, 024 7651 1677) wire machines, the VZ300L and VZ500L, incorporate many of Sodick's key features including linear motor drives with linear scales - the ideal drive mechanism to maintain high speed and high response, whilst retaining initial positioning accuracy for years. The compact VZ300L offers new EDM users excellent machine reliability and performance, enhanced by the many functions fitted as standard, including Heart-NC on board programming, advanced corner control, automatic float control, new power supply with perfect active control discharge technology, and more. The VZ500L is a medium-sized machine of a similar configuration, ideally suited to tool shops machining components of different sizes, from part machining to mould making. HONING TECHNOLOGY Sunnen's (01442 393939) new patented multi-feed honing technology gives offers a revolutionary choice of tool feed modes to achieve the shortest cycle times, lowest part cost, and longest abrasive life. Multi-feed combines Sunnen's new controlled force tool feed with its controlled rate feed system. The two different tool feed modes allow the user to select the better option to suit the workpiece geometry, material and tool type/size. Multi-feed technology is available as an option on new machines in Sunnen's SV-1000 and SV-500 Series, as well as a retrofit for existing machines in these series. Controlled force honing works like cruise control to ensure the optimum cutting load on the honing abrasive throughout a cycle, irrespective of the incoming part's hardness, geometry or size variation. Depending on the application, controlled-force honing cuts cycle times by as much as 50 per cent, lengthens abrasive life for lower consumable cost, and allows finer control of surface finish parameters than ever before possible. Controlled-force honing works with Sunnen's MMT, PH and new KRQ tools. Controlled force honing is an enhancement of Sunnen's controlled-rate system for tool wear compensation, which is already capable of adjusting tool size in increments as fine as 0.1 µm. Controlled-rate tool feeding is typically used with plated-diamond CGT honing tools, which use a sleeve of abrasive for full contact with the bore surface. Image: Controlled force honing is an enhancement of Sunnen's controlled-rate system for tool wear compensation CGT tools are frequently used on cast iron and powder metal workpieces, segmented bores, or parts with multiple lands, ports, keyways or crossholes in the bore. Sunnen's machine control provides up to five feed expansion profiles that can be used during a cycle for rapid part touch, cutting, sizing, finishing and spark-out. And Sunnen's new KRQ honing tool marries the precision performance of expensive custom tools with the low cost and quick-change flexibility needed for mid-volume production runs. Mazak Optonics Corporation (UK, Yamazaki Mazak, 01905 755755) introduced its SuperTurbo-X Mark III RTC 2D laser cutting system. This cuts thin to thick sheets, cubic components, taps and even chamfers, enabling firms to cut a wide range of laser cut parts. A rotary table is standard equipment for cutting round pipe up to a maximum diameter of 375 m, and square tubes up to 150 mm. This 2.5 or 4 kW laser machine includes an integrated tapping capability for a range of thread sizes. It accepts sheet sizes up to 1,500 by 3,000 mm and can delivered with a large range of automated material handling systems. The STX Mark III RTC uses features developed for Mazak's Hyper Series machines. They include intelligent set-up functions for automated nozzle spatter removal, a three-station nozzle changer and focal point measurement and adjustment capability. These features are components of Mazak's Opti-Pod, which helps to minimise system set-up time, improve extended unattended operation and maintain optimised machining conditions. A new servo focus torch significantly reduces piercing time and increases productivity. Image: The STX Mark III RTC uses features developed for Mazak's Hyper Series machines Additional new technology includes a high accuracy auto centring lens and nozzle design that further reduces set-up and increases productivity, as well as pierce, plasma and burn sensing to assure consistent performance over a wide range of materials. Omax Corporation (01244 409199) introduced its 120X JetMachining Center, which has been designed for manufacturers with large scale abrasive water jet requirements. Four models of are available, with lengths of 4, 6, 8, 10, 11.5, and 13.4 m. Each of the models is 3 m in wide. It also introduced the new A-Jet, a short for articulated jet that cuts accurate bevelled edges at angles over a range of 0° to 60°, determined by the machine operator or part program. It can be used to easily produce bevelled edges when cutting countersunk holes, and it can also cut parts with complex geometries. The accessory features a fixed focal point design, where the XYZ axes need not be moved as the head tilts. MORE EFFCIENT MACHINING A first look at Mastercam X5 was offered (4D Engineering, 01285 650111). The new revision boasts new dynamic milling techniques that constantly adjust the toolpath to ensure the most efficient cut possible, allowing use of the entire tool flute length, often eliminating the need for multiple depth cuts. New dynamic milling techniques include Dynamic Rest Mill and Dynamic Contour. Mastercam's multiaxis suite has new machining techniques and a new, easy, workflow-oriented interface. The new 3D surface high speed OptiRough toolpath is a new technique designed to remove large amounts of material quickly, using dynamic milling motion. Large, aggressive cuts are followed by fast, smaller up-cuts, safely delivering a fully roughed part fast. Hybrid finishing intelligently blends two efficient cutting techniques in a single toolpath. This new toolpath evaluates the model shape and smoothly switches between Constant Z cutting and Constant Scallop machining. The result is a dramatically finer finish with less work. Gibbs and Associates, a Cimatron company and developer of GibbsCAM software for programming CNC machine tools (UK, Tech CADCAM, 01284 754781), demonstrated forthcoming features of GibbsCAM MTM (multi-task machining). Image: GibbsCAM - hybrid finishing intelligently blends two efficient cutting techniques in a single toolpath MTM has been redesigned to reduce the time and effort required to develop post-processors, generate CNC programs and simulate machine motion. With its redesign, the software will program more complex machines and give users greater control of post-processor creation. Users interact through a new Machine Manager module to readily create definition files for multi-axis machines of various configurations; define assembly files for machine simulation; specify kinematics of machine configurations (axes, part stations, tool groups, etc.); specify machining preferences, such as work envelope, cycles and most frequently used options; and define interoperational events (tool or tool group changes, spindle changes, parking locations, etc.). There's also extended Swiss-style machine support. This sees improves and extends support for thread whirling. Machine Manager will replace the current MDD (machine definition) Editor to support programming and synchronisation for machines with more than three flows. Machine simulation is also improved. In addition to this, there are other new features. Auto Wizard within Hole Manager will allow storing default settings for reuse at any time, and the Auto Wizard button will allow invoking the Hole Wizard multiple times, quickly. Using the streamlined Hole Manager options, users will be able to take a part with hundreds of holes and, in just three mouse clicks, auto-recognise and program them all. Attribute Manager & Feature Manager offer new tagging capability that opens the door to querying, creation, modification, sorting and filtering of elements and element sets by user-defined and system metadata tags, called attributes. When importing models, GibbsCAM users will be able to control whether and how to import attributes and geometry. Users can define features of any kind, by grouping feature geometry or grouping elements that share a specified attribute. Entities defined as features, or otherwise tagged with attributes, can be visually identified and isolated for manipulation, copying or machining. When a part contains user-defined features, or when any of its elements are tagged with a colour attribute, users will be able to switch among colour modes using Colour Manager. New Hole Capabilities allow selecting, recognising and drilling holes. Several new variable peck cycles and various options for user defined custom drill cycles will be available, and a new check box will enable reverse-order drilling. Hole features will be selectable by face (or set of faces), or by co-ordinate system to which the hole Feature is aligned. Also, a hole feature will be selectable by picking any of the hole's interior faces. Automatic Feature Recognition will automatically recognise entities that resemble holes, when a user specifies a face (or set of faces) or co-ordinate system. Imported Feature and Colour Recognition/Preservation sees GibbsCAM read CAD model attributes, then recognise and preserve them as attributes in the GibbsCAM part file. Hole features in the model will be interpreted as hole features recognisable and usable by Hole Manager and its Auto Wizard. Sescoi (0844 561 7014) previewed its WorkNC V21 CADCAM system. Ten fold speed improvements in the processing and calculation times in WorkNC V21 CAM software have been achieved through the implementation of 64-bit and multi-core processing algorithms, which take advantage of the latest advances in computer hardware. And for electrode manufacture, the new WorkNC Electrode Module uses the capabilities of WorkNC-CAD Hybrid Modelling to make it easy to extract 3D electrode geometry directly from the CAD model. From making things to measuring them and Carl Zeiss (01788 821770) unveiled a new bridg-type, multi-sensor CMM, the ACCURA. A configurable unit that can be used on the shopfloor, special software, such as GEAR PRO for gears and HOLOS NT for freeform surface measurements, is integrated along with CALYPSO measuring software. Available at "a very economical price for this performance class", if requirements change, different sensors and software can be added. ACCURA can make use of MASS technology, which, combined with an RDS articulating probe holder, permits the fast, measuring program-guided change between contact sensors and the ViScan and LineScan optical sensors, during a CNC run. VAST family contact measuring sensors and the DT single-point sensor can also be used. Note: Note: The above technology is not necessarily available in the UK. Recent technology already launched in the UK has not been included. Box item 1 Other MAG developments • A new automatically changed grinding attachment adds surface finishing to the one-stop processing capabilities of MAG's vertical turning centres, allowing finishing of ID, OD and plane surfaces on parts up to 4,700 mm diameter. • The comanies new modular HMC 1250/1600 horizontal machining centre has a new 6000 rpm/46-kW, 180,000-position A-axis tilt-spindle for 5-axis horizontal machining on large aerospace and energy parts. • The SPECHT 500/630 horizontal machining centre takes modularity to a new level, offering linear motor or ballscrew drives, CAT-40 through HSK-100 tool interfaces, six spindle options, four control options and three 5-axis configurations. The US-built machine is engineered around a box-in-box, moving-table design for low-inertia responsiveness and delivers accuracies up to 4 microns at 260 Nm full-torque cuts. Designed to the highest green standards, the SPECHT has an industry-leading 1.8 m wide footprint and conserves energy with no warm-up, multi-step sleep mode, regenerative drives, half the normal coolant requirements and only one-third the air-extraction needs. Its maintenance-friendly design shows SPECHT's automotive industry lineage, with front or rear spindle removal and one-cabinet fluid management centre for grease, pneumatics, coolant and hydraulics. • MAG's new vertical turning centres with of 5, 6, 7 and 8 m tables and with fixed and adjustable rails have high end specifications, like 2,500 mm ram travel and 1,500 mm minimum height under the rail. • The company's new VDF 800 DUS Big Bore CNC lathe has a 365 mm spindle diameter, 820 mm swing over the bed, 8,000 kg part capacity, and 20 kN Z-axis cutting force. Ideal for drill string parts, drive shafts and pipes, the machine has a main drive rated at 37 kW (continuous), 55 kW) maximum, with 7,200 Nm maximum torque. A 900 rpm top speed – nearly twice as fast as comparable lathes – gives flexibility to handle a wide range of smaller diameter parts by maintaining the tool surface speeds needed to produce required finishes. • And, finally, a new CNC retrofit program is offered for MAG legacy brands, including Giddings & Lewis, Cincinnati Milacron and Fadal. At IMTS, a Fadal 3016FX milling machine was shown retrofitted with a Fagor 8070 control and digital Sercos drives. A retrofit of this type saves about 50 to 75 per cent of the cost of a new machine, it is claimed. Box item 2 Mori Seiki and DMG in detail DMG/Mori Seiki USA exhibited 38 Mori Seiki and DMG machines, with the stand organised seven technology centres, including: automatic and universal lathes; turn mill machines; 5-axis machining centres; horizontal and vertical machining centres; Dura eco machines; and advanced technology (ultrasonic and lasertec solutions). The alliance between DMG and Mori Seiki has significantly increased the range of products available, say the companies, with single-source service and support. Ten newly developed models were shown for the first time, including Mori Seiki NHX4000, NLX2500/700 and NVX5000 machines, while DMG highlights included the Ultrasonic 10, a broad selection of automatic lathes, the DMF 260 linear travelling column machine and the DMU 50 eco machine. [] Mori Seiki's X-class saw its debut, with the NTX1000 integrated mill-turn available to order at the show. The NTX1000 is said to be an ideal choice for machining small precision parts for medical equipment and measuring instruments that have complex shapes, but need high precision and high efficiency machining. The machine features original technologies, high operability, space saving design, thermal displacement measures, MAPPS IV control with integrated ESPRIT CADCAM, and a wide variety of models. Original technologies - the NTX1000, with 370 mm turning diameter and 424 mm turning length, uses Mori Seiki's original DDM (Direct Drive Motor), ORC (Octagonal Ram Construction) and BMT (Built-in Motor Turret) technologies, offering high precision complete machining of small precision parts. (DDM, ORC and BMT are trademarks or registered trademarks of Mori Seiki Co.) High operability – it uses a rounded cover design, which is commonly used by the X-class machines. Additionally, it offers improved operability by using a slanted keyboard. Space saving -the installation area has been reduced by approximately 40 per cent, compared to Mori Seiki's conventional models. Thermal displacement - as one of measures against thermal displacement, the NTX1000's spindle 1 is designed to always maintain its centre in the same position, and its headstock structure is symmetrical in the X and Y-axis directions from an anterior view. In addition, the slideways of the ORC are located diagonally opposite each other, so that their distortion in response to heat is symmetrical. Since thermal displacement in the slideways is offset, the machine can maintain the centre of the moving parts in the same position, achieving high precision machining. MAPPS IV + ESPRIT - the NTX1000 uses the MAPPS IV high performance operating system for its operation panel. The combination of automatic programming software (standard) and ESPRIT CAM software (standard) allows the machine to handle complex machining programming and to flexibly meet customer needs. In addition, the 3D interference checking function (standard) checks interference between spindles, workpieces, soft jaws, tools, holders, and turrets in 3D. If interference is detected, the machine stops, in both automatic and manual modes. This offers the "world's best protection against interference". Variety of models - eight models for different machining needs are available. Although they are general-purpose machines, each of them flexibly handles machining that is usually performed on special machines. [] The NHX Series of horizontal machining centres (NHX4000 [400 mm pallet], NHX5000/40 [500 mm pallet]) offers improved cost performance by drastically reducing the number of parts, and is designed to reflect current market needs and 3,000 feedback comments from customers. Features include: high speed; high rigidity; high accuracy; energy saving; MAPPS IV + ESPRIT; compliance with safety standards; and variations. High speed - The NHX4000 and NHX5000 have a rapid traverse rate of 60 m/min. The NHX4000's pallet indexing time is 1.0 second (1° indexing specification), and the NHX5000's is 1.49° (90° indexing specifications). Both models offer dramatically increased productivity by reducing non-cutting time. High rigidity – the NHX Series achieves high rigidity and stable machining by using a thick, high rigidity bed with the X and Z-axis linear guides placed in a high position; the spindle has a large diameter bearing, and table and pallets clamped securely. High accuracy -the NHX Series offers improved positioning accuracy by reducing weight of moving parts including a column. Additionally, it uses direct scale feedback as standard to ensure high accuracy. Energy saving - the NHX Series is designed to reduce environmental burden and running costs. While a hydraulic unit pump used in the conventional model rotates all the time to maintain pressure, the pump used in the NHX Series can be stopped during standby, because an accumulator is attached to the hydraulic unit. In addition, the number of motors has been reduced. The NHX Series has achieved an approximately 40 per cent reduction in total power consumption compared to the conventional model. MAPPSIV + ESPRIT - the NHX Series uses the MAPPS IV high-performance operating system for its operation panel. In addition to automatic programming software (standard), ESPRIT CAM software is available as an option. The combination of MAPPS IV and ESPRIT allows the machine to handle complex machining programming and flexibly meet customer needs. Compliance with safety standards - the NHX Series conforms to safety standards all over the world, including CE Standards, UL Standards and ANSI. Variation - since a wide range of variations, including ATC without arms and configurations without APC, is available, the NHX Series can also be used as special machines for the automobile industry. [] The NVX5000 Series of vertical machining centres (NVX5060, NVX5080, NVX5100) has evolved from the NV5000 Series as a result of a full model change. The NVX5000 Series is designed to reflect current market needs and has taken on board feedback from 1,000 customers. The machine features: high rigidity; thermal growth countermeasures; energy saving; MAPPS IV plus ESPRIT; and compliance with safety standards. High rigidity - by using slideways for all axes, the NVX Series offers improved vibration damping performance and dynamic rigidity. It also offers longer tool life and capabilities for heavy-duty cutting. Additionally, it achieves a rapid traverse rate of 30 m/min in all axes. Thermal displacement countermeasures - the NVX Series uses a spindle in which air and cooling oil pipes are arranged symmetrically relative to the centre of the spindle. The heat symmetrical structure minimizes thermal displacement in the spindle by dispersing heat evenly. In addition, coolant circulation inside castings (a bed and column), which is available as an option, allows the machine to achieve active control over thermal displacement caused by cutting heat and changes in the ambient temperature. Variation - three variations, for different workpiece sizes, are available for the NVX5000 Series: the NVX5060 (X-axis stroke, 600 mm), NVX5080 (800 mm) and NVX5100 (1,050 mm). There are also 40 and 50 taper spindles Energy saving - the NVX Series is designed to reduce the environmental burden and running costs. It saves power consumption by stopping the spindle motor, servo motors, and fans inside the control panel during standby, as well as by using LED lighting. The total power consumption has been reduced by approximately 35 per cent, compared to the conventional NV5000 Series. MAPPS IV plus ESPRIT - the NVX Series uses the MAPPS IV high performance operating system for its operation panel. In addition to automatic programming software (standard), ESPRIT CAM software is available as an option. The combination of MAPPS IV and ESPRIT allows the machine to handle complex machining programming and offers flexibility. Compliance with safety standards - the NVX Series conforms to safety standards all over the world, including CE Standards, UL Standards and ANSI. First published in Machinery, October 2010
