For shaft parts, CNC turning is suitable for those parts with the following characteristics: complex structure or shape, difficult general processing operation, long working hours and low processing efficiency. Machining precision consistency requirements of higher parts. Changing cutting conditions of parts, such as parts due to the shape characteristics of the need to cut grooves, holes, car threads, etc., processing to change the cutting parameters. Small batch, but each batch variety and a certain degree of complexity of the parts.

For worm shaft parts with keyway, radial hole (including screw hole), end face distributed holes (including screw hole), such as shaft with flange, shaft with keyway or square head, can also be processed in the turning center, in addition to ordinary NC turning, all kinds of slots, holes (including screw holes), surfaces and other machining surfaces on the parts can also be processed. The process is highly concentrated, its processing efficiency is higher than ordinary NC turning, processing accuracy is more stable and reliable.
