目前研究将椭圆振动切削应用于光学玻璃零件钨合金模具的超精密加工。钨合金有望成为替代烧结碳化钨和CVD碳化硅等传统模具材料的新型模具材料。但由于刀具磨损快、脆断、与刀具粘连等原因，普通切削加工无法精确完成。因此，超声椭圆振动切削应用于钨合金的超精密加工。通过椭圆振动切削获得了实用的超精密模具，并成功应用于玻璃成型。
Elliptical vibration cutting is applied to ultra-precision machining of tungsten alloy molds for optical glass parts in the present research. The tungsten alloy is expected as a new mold material instead of conventional ones such as sintered tungsten carbide and CVD-silicon carbide. However, it cannot be finished precisely by ordinary cutting because of rapid tool wear, brittle fracture and adhesion to the tool. Therefore, the ultrasonic elliptical vibration cutting is applied to the ultra-precision machining of tungsten alloy. Practical ultra-precision molds are obtained by the elliptical vibration cutting, and they are applied to glass molding successfully.
