88 MoldMaking Technology July 2015 Pg. 5 Machining High-Speed Machining Center Built for Mold and Die Work GF Machining Solutions' Mikron HSM 500 MoldMaster (MM) high-speed milling machine is designed as an all-in-one production system, enabling shops to build a range of mold- and die-related components, from 58 Rc steel mold cores to hot pressing dies and sinker-EDM electrodes for intricate mold cavities. The machine is equipped with a 42,000-rpm HSK spindle that uses ceramic hybrid ball bearings with oil-air minimal lubrication, as well as liquid-cooled stator jacket and bearings. This vector-controlled motor spindle ensures fast acceleration to full speed as well as high torque at low speeds. As a comple- ment to the high-speed spindle, the machine cuts at feed rates as fast as 784.4 ipm (20 m/min.) and rapid traverses as fast as 1,574.8 ipm (42 m/min.). GF Machining Solutions / 847-913-5300 / gfms.com/us Three-Axis Machine Equipped with Motion Control Hurco's three-axis VMX42HSi milling center is equipped with the company's UltiMotion motion control system designed for longevity and rigidity, featuring larger linear rails that are wedge-locked to the frame to reduce vibration. The control uses software algorithms for motion planning instead of conventional hardware, optimizing look-ahead by as much as 10,000 blocks, and is said to reduce cycle time by 30 percent, while improving part surface finish. The high-speed machine features Yaskawa direct drive servos, an 18,000- rpm integral spindle with ABEC-7 ceramic hybrid bearings, linear thermal compensation and X-Y-Z travels of 42" x 24" x 24". An air-over-oil spindle lubrication system continuously distributes oil evenly to ensure long bearing life for the high-speed spindle. Hurco Companies Inc. / 317-293-5309 / hurco.com Modular Workholding Cuts Setup Time Single Source Technologies' FCS Modular Clamping System (Breyl) is designed to provide unrestricted access to five surfaces of the work- piece, enabling operators to spend less time on setups and more time on machining. According to the company, this increased production time translates into higher machine utilization and lower costs. During the CAD/CAM stage of part production, a grid is projected on the workpiece and the system calculates the best way to attach the part for machining and chip evacuation. After checking for possible interferences with other holes, it automatically arranges the fixing seats based on the dimensions of the workpiece and combination of pallets and clamping available. Permanent reference points enable easy removal and reas- sembly of the workpiece on the pallet or base gages to keep the zero reference point locked in.

The VMC features a rigid and accurate double-column structure that sup- ports a +90/-120-degree trunnion table. The center of gravity of the trunnion table and therefore the workpiece is low, enabling both heavy-duty cutting and high-speed finishing. The table also enables accurate positioning for simultaneous five-axis cutting. The machine also comes equipped with the company's Super-NURBS, enabling high feed rates with ultrafine finishes, reducing the need to hand-polish molds and therefore increasing productivity.
