When machining parts on CNC lathe, the working procedure should be divided according to the principle of process concentration, and most or all surface processing should be completed as much as possible under one clamping. According to the different structure shapes, the outer circle, end face, inner hole and end face are usually selected for clamping, and the design basis, process reference and programming origin are unified. In batch production, the following methods are commonly used to divid

The standard of precision parts processing industry is very strict. There are different processes such as feeding and discharging. The size will also be different according to the specific requirements of the products, and the requirements of the processing accuracy will be different. Generally speaking, the requirements of precision machining accuracy are very high, sometimes even to the number of micrometers under 1 mm. If the size difference is very big, the product will become waste and need
