Point
Machining of brass workpiece (artificial tooth with abutment) was performed with a φ22 small and high-speed spindle on a CNC automatic lathe (STAR MICRONICS CO., LTD. / SR-20R IV type E).
Mounting a compact / high-speed spindle enhances the speed of the CNC automatic lathes, enabling fine precision machining.
