Hyundai WIA’s VMC Series Specifically Designed for Moldmaking

January 30, 2012 By Motion Control Tips Editor Leave a Comment

Hyundai WIA (www.hyundai-wiamachine.com) has introduced a new Hi-Mold Series vertical machine centers which are specifically designed for machining precision molds. The Hi-Mold Series boasts a bridge design that delivers low-heat and high rigidity characteristics for a high-precision moldmaking.

The axis’ main head moves left to right and up and down on the cross beam to make the table turn front to rear. All of the axes are driven by double-nut ball screws of high precision to stop thermal increase while machining. Offering an outstanding repeatability and positioning, the double pretension design also provides practically no thermal increase. Reducing any backlash, all ball screws are directly linked to the servo drive motors avoiding the need for belts or gears.

The linear motion guideways help achieve fast axis movement trimming on machining time and non-cutting time. The spindle traverse for the A/C axes is 70/150 rpm while for the X/Y/Z axes is 50/50/50 m/min.

Hi-Mold VMC’s main spindle is engineered for precision machining delivering 24,000 rpm, geared with precision-class angular bearings offering fast acceleration or deceleration. Even at the greatest rotation levels, the spindle maintains low vibration, reducing thermal transmission to the main spindle and therefore, promoting stability.

An optional 40,000-rpm main spindle is offered for high-quality machining of mold cavities and bases. To ensure that oil temperature remains constant and to reduce the growth in the spindle caused by heat distortion, it also gets a spindle oil chiller that can control the spindle temperature.
