Central to the Ellesco stand (6-370) will be a selection of machines from Timesavers, which offers a range of deburring and wide-belt grinding machines that deliver deburring, precision grinding and edge rounding on sheet metal and plate components, large and small.
Making its UK exhibition debut will be the Timesavers 42 series 1350 HWRB machine equipped with the Hammer Head heavy slag removal system, which will be combined on the show machine with edge deburring and radiussing heads. This specification is suitable for the processing of heavily-drossed flame- or plasma-cut parts up to 1,350 mm wide (1,600 mm option). The machine also has the ability to process a range of laser and punched materials, including stainless steel, aluminium, carbon steel, zinc coated and laser-film products.
Another Timesavers machine on show is set to be the mid-range 32 series, which will be demonstrating the ability to deburr laser-cut components. Suitable for deburring, edge rounding and/or finishing different materials, the 32 series is equipped with Timesavers’ rotary brush technology. The use of a vacuum table as standard means that very small, lightweight parts can be processed, with the whole cycle being monitored from the angled control panel and the large window. Other standard features include a 1,100 mm working width, LED beam on the infeed side that indicates machine status, frequency-controlled motors for process control, and ease of changing the brushes, which can be specified to suit a range of materials and duties. Completing the operation is an automatically adjustable table height of between 0 and 100 mm, and conveyor speeds variable from 0.2 to 8 m/min.
Concluding the Timesavers line-up at MACH will be the 12 series, the baby of the range. Available in 225 and 600 mm working widths, the 12 series has been purpose-designed for deburring and finishing sheet-metal parts. The machine can be equipped with an abrasive belt, cylinder brush or rotating disc, or a combination, with the grinding belt removing vertical burrs and subsequent roller brush or disc operations eliminating side burrs, while producing edge breaking at the same time. The 12 series can automatically adjust the table height between 1 and 75 mm, while frequency-controlled drives maintain workpiece flow at anywhere from 3 to 9 m/min.
A completely different approach to deburring will be demonstrated by the WMS Engineering robot concept appearing on the stand for the first time. This system is designed for the precision deburring of parts by taking the component to the tool, the tool to the part, or a combination dependant on the application. Tools include high-speed (9,000 rpm) mills, drills, brushes, stones and abrasive wheels.
WMS Engineering’s modular approach to system build means that it can produce complete turnkey solutions to customer requirements. The versatility of the WMS system is that it is equally at home processing internally and externally machined components, as well as automatically monitoring the results of its work, with the robot manipulator able to precisely position the edge to be deburred.
For those seeking solutions to their weld-dressing processes, the fully automated robot cell from Autopulit provides the answer. The robot cell on display at MACH 2020 will highlight the ability of Autopulit to deliver belt grinding for weld dressing, finishing and paint preparation tailored to individual customer requirements. This capability is achieved by utilising robots to position work around single or multiple abrasive/polishing stations, or manipulating consumables around a component.
An almost limitless combination of axes, consumables and handling set-ups streamlines workflow. Quality is maintained via sensors that detect and compensate for any geometrical deviations in the workpiece caused by the welding process. The key advantages of the Autopulit system are its ability to efficiently manage short or repetitive batches, while reducing cycle times compared with a manual process. Furthermore, the system allows for a variety of parts to be processed in-line, without any need for set-up changes as different tools can be selected by the system according to process requirements.
