What are the advantages of CNC lathes and ordinary machine tools?

Ordinary lathe is driven by gears and ordinary screw nuts. Because of the gap between motion pairs and the inaccuracy of manual operation, the repetition accuracy is low. Ordinary lathe measurement needs manual measurement after shutdown, which has large measurement error and low efficiency. Suitable for parts with small batch, low precision and odd jobs. Its investment is lower than that of numerical control, but it requires higher operating skills of workers, so the salary level is high. The scrap rate and productivity of junior workers will give you a headache.

CNC lathes rely on stepping motors to drive ball screws. Because the ball screw can have interference and transmission without clearance, the accuracy is mainly guaranteed by the machine itself and procedures. It can be automatically measured in the process of machining, and can automatically compensate the errors caused by tool wear and other reasons. Therefore, the machining quality is good and the precision is stable. You can also use programming methods to turn parts with complex shapes that are difficult to be machined by ordinary lathes. Suitable for parts with high precision, large batch and complex shape. But small batch production is also very useful. Its maintenance cost is higher than that of ordinary lathe.
