The basic parts of machines or parts are boxes, which can assemble parts into a whole, such as shafts, sleeves, gears and other parts, and can ensure that all parts are in the correct position, coordinate work to transmit power, so the processing quality of the box body will directly affect the accuracy, performance and service life of the machine or components. Common box parts include: Machine tool spindle box, machine tool feed box, gear box, gear box body, engine block and base, etc. According to the different structural forms of box parts, it can be divided into two categories: integral box and separated box. The former is integral casting and integral processing, which is difficult to process but has high Assembly precision; The latter can be manufactured separately, which is convenient for processing and assembly, but increases the assembly workload. Although the structural forms of the box are various, they still have the same main characteristics: complex shape, thin and uneven wall, cavity shape inside, many processing parts and great processing difficulty, there are not only holes and planes with higher precision requirements, but also many fastening holes with lower precision requirements. Therefore, the amount of mechanical processing Labor for box parts in general medium-sized machine tool manufacturers accounts for about 15% of the total product processing amount-20%.
