CNC centering lathes are generally used to process small parts from bars, and the batches are large, many of which are formed at one time. As long as it involves bar processing, the diameter should not exceed 20mm. The advantage of the center lathe with the feeder is great (because the center lathe must be equipped with a feeder for processing), so it is a small independent production line. It is processing speed, labor cost, and he has advantages.
