At EMO in Hall 26, Booth D29, Hyundai WIA will show its Hi-MOLD Series of bridge type, high speed machining centers—including the Hi-MOLD65000, which will make its European debut. The Hi-MOLD6500 is a high speed bridge-type machining center particularly suited for precision machining due to the bridge design’s high rigidity and the generation of low heat, the company states. The head of the main axis moves up and down and left and right on the cross beam. The table in turn moves front to rear. In order to eliminate thermal growth during machining, all axes are driven by high precision double-nut ballscrews, which feature internal cooling as an option. The double pretension design provides outstanding positioning and repeatability with virtually no thermal growth. All ballscrews are connected directly to the servo drive motors without gears or belts, to eliminate backlash.  Rapid high speed axis movement is achieved by the use of linear motion guide ways. This reduces non-cutting time and decreases machining time for greater productivity. Rapid traverse: X/Y/Z axes, 40/40/40 m/min; Cutting speed is 24 m/min.

The main spindle is designed for high speed and high precision machining at 15,000 rpm (20,000 rpm optional) with ultra-precision class angular bearings providing high speed accel/decel for smooth machining at high rpms. The built-in spindle design delivers little noise and vibration even at the highest rotational speeds, guaranteeing extremely stable machining by minimizing thermal transmission to the main spindle. Thru the spindle coolant guarantees stable machining and increases tool life by decreasing heat generation caused by high speed machining, particularly when executing deep hole machining. Spindle taper is Big Plus 40, spindle speed is 15,000 rpm (optional 20,000 rpm), spindle output is 30 HP (25 HP continuous), spindle torque is 123 foot pounds, and spindle drive is built in.
