The processing principle of mechanical processing

by:Xavier      2020-07-12

high requirement of machining is a very rigorous process, to the quality requirement of the operating personnel is also very high, because to ensure the high precision and high precision quasi processing, then the principle of machining process should pay attention to what? To introduce you to the following:

the first point: to separate coarse and fine parts, because of roughing and fine machining on the cutting force, clamping force and calorific value are not the same, relative to the amount of fine processing, rough machining of cutting, cutting force, calorific value significantly more than the fine processing, and processing are more prone to surface hardening phenomenon, its internal stress is bigger also. So in order to assure the precision of machining, must separate roughing and fine machining. For some high accuracy requirement of parts before put them in fine machining after rough machining, as well as cooperate with low temperature annealing to eliminate internal stress, so as to ensure its high precision.

the second point: for the choice of equipment is reasonably accurate, for rough machining should be chosen on the power of the machine tool, because of its main aim is to cut off most of the machining allowance, less to the requirement of accuracy is high, but for fine machining are asked to choose high precision machine tool for processing, reasonable choice can not only guarantee machining accuracy of machine tool, can prolong the service life of machine tool.

the third point: the processing sequence of reasonable arrangement of machining is very important, such as heat treatment process should be arranged in front of the mechanical processing; To eliminate internal stress failure treatment, conditioning treatment process should be arranged before finishing after the rough machining; In order to improve the mechanical properties of the parts of carburizing, quenching and tempering after general arrangement in the mechanical processing.

in v. machining is a very rigorous process, operators need to be carried out in accordance with the principles of management of accurate.
