1. Effective selection of machinery and equipment. Rough mechanical parts production hardware machinery and equipment finishing is mainly to disconnect most of the remaining amount of mechanical equipment processing, without high-precision machine equipment parts processing, so the initial processing should have greater rights and high-precision CNC lathes to carry out full The process insists on applying a relatively high precision machinery. Unsmooth and deep processing are performed on different equipment, which can make full use of the working capacity of the machine and equipment, and can increase the service life of the precision machine.

Second, in order to ensure the machining precision of carton machine parts, the production and processing of coarse and fine machine parts are the best. Due to the large amount of drilling when the rough mechanical parts are produced and processed, the cutting speed, clamping force, heat, and surface of the mechanical parts have significant cold work hardening, and the product workpiece is under great thermal stress, if it is not smooth , After the non-smooth mechanical parts are produced and processed continuously, the precision of the parts will be quickly lost because of the heavy ground stress. Production and processing of mechanical parts for some precision machined parts. After initial processing and deep processing, the whole process of ultra-low temperature quenching should also be distributed or cold worked to remove internal in-situ stress.

Third, in the processing line of precision machinery manufacturing parts, the whole process of quenching and tempering treatment is often allocated. The addresses are allocated as follows: the whole process of quenching and tempering treatment, improving the machining characteristics of drilling and production of metal materials, such as quenching, quenching, quenching, generally allocated in the production and processing of mechanical parts. Removal of internal in-situ stress, such as cold working, adjustment and treatment, such as general construction plan, after initial machining, but in progress. In order to improve the physical properties of plastic mold components, such as nitriding heat treatment and quenching, they are generally distributed in the production and processing of mechanical parts. For example, the deformation after quenching and tempering treatment is large, but the final production process must be distributed.
