The efficient and practical method of precision spare parts processing

If the precision spare parts processing method is not correct, the processed products will also be substandard, so what is the efficient and practical method of precision spare parts processing? Let's go with the following introduction to understand it.
 
Precision spare parts processing efficient and practical methods
 
(1) to reasonably select the equipment. Rough machining of mechanical parts is mainly cut off most of the machining margin, do not need high precision machining of mechanical parts, so rough machining should be greater power and high precision machine tools, to complete the process adhere to the use of a relatively high precision machine. Roughing and finishing on a different machine, you can give full play to the capacity of the equipment, can extend its life precision machine tools.
 
(2) In order to ensure precision parts processing accuracy, rough and fine mechanical parts processing from the best respectively. Because when the coarse mechanical parts machining, cutting volume, the workpiece cutting force, clamping force, heat, mechanical parts machining surface has obvious processing hardening phenomenon, the workpiece in the larger internal stress, if rough, rough mechanical parts machining is completed continuously, the parts precision will soon lose due to stress redistribution. For some high precision parts of mechanical parts processing. After roughing and finishing, should also be arranged or aging treatment low-temperature annealing process to eliminate internal stresses.
 
(3) in the precision parts processing process route, often arrange the heat treatment process. Location arrangements are as follows: heat treatment process to improve the cutting performance of the metal, such as annealing, normalizing, tempering, generally arranged in the mechanical parts processing. Internal stress relief, such as aging treatment, conditioning treatment, such as the general layout, after rough machining, but in the finish. In order to improve the mechanical properties of the parts, such as carburizing quenching and tempering, generally arranged in the machining of mechanical parts. If the deformation after heat treatment is large, but also to arrange the final machining process.
 
In summary, "precision parts processing efficient and practical methods" is introduced to this, precision parts processing work to achieve perfection, you must use the correct and scientific method to put into the precision parts processing work, in order to adapt to the needs of the continuous development of enterprises.
