On Stand 640 in Hall 20, the company will be showing the range of Kitamura machining centres, with three high-end solutions on display. These machines will appear alongside the Hanwha XD26II sliding-head lathe, the twin-spindle SMEC SL2500BLSY turning centre and the latest Hanwha series of cobot (collaborative robot) automation solutions.
The SMEC SL2500BLSY turning centre builds upon the foundation of a single-piece Meehanite casting that is heavily ribbed with a torque tube design, which in combination with box slideways, offers vibration dampening and thermal displacement characteristics. Also featured is a 10” chuck (12” optional) with a 650 mm swing-over-bed capacity that allows a maximum machining diameter of 360 mm and a maximum turning length of 520 mm. Bar capacity is 76 mm, while an 18.5 kW spindle motor supports the heavy-duty manually loaded or automatically bar-fed machining of relatively large diameter parts.
Complementing the high-speed main spindle is a sub-spindle with a 6” chuck that is driven by a 7.5 kW spindle motor capable of 6,000 rpm. The heavy-duty live turret offers 12 tooling positions, features a large diameter three-piece Curvic coupling and provides 3,545 kg of hydraulic clamping force. Each turret station accepts both milling and turning tools, with milling tools capable of reaching rotational speeds of 5,000 rpm credit to the high-torque 3.7/5.5 kW motor that drives the BMT65 configured system. The machine is driven by a FANUC CNC.
Alongside the SMEC SL2500BLSY will be the Hanwha XD26II, which at MACH will be driven by a FANUC 32i-B CNC (Siemens 828D also available). The machine also incorporates the facility to switch from guide bush to non-guide bush operation. With a 26 mm bar capacity and a 6,000 rpm, 5.5 kW spindle motor that is complemented by an 8,000 rpm, 2.2 kW sub-spindle, Dugard says that the Hanwha XD26II should suit any small-parts turning shop.
The Hanwha XD26II incorporates a multitude of tooling configurations with five OD turning tools, an additional 10 front and back-working tools, five driven cross-tool stations, and two driven and two static tooling stations for the sub-spindle – not to mention the gun-drilling station. With the configurable tool platens and positions, the Hanwha XD26II offers fast set-up times, a spacious work envelope with plentiful operator access and, most importantly, kinematics that position all tool stations close to the workpiece.
Numerous configuration options are available that vary from part and chip conveyors, through to oil and mist chillers, gripper units, powered guide-bush systems, tool and tap breakage detection systems, length measuring units, and more.
