Machining process for stainless steel part of power-driven equipment

Abstract

The invention provides a machining process for a stainless steel part of power-driven equipment, which comprises the following steps of: 1, casting and forming: casting and forming through a mold, and reserving 3-5mm allowance on a single side of an inner cavity; the second step of grinding and scrap removing, wherein the clamping face of the semi-finished product is ground manually through a grinding machine; 3, numerical control machining is conducted, specifically, the part is machined through numerical control, machining is conducted three times, and the three times of machining are rough machining, semi-finish machining and finish machining respectively; and the margins of 0.7 mm, 0.15 mm and 0.05 mm are reserved in the three times of processing. 4, process chamfering is conducted, specifically, bevel angles not larger than 0.1 mm are chamfered at the edges of the inner cavity of the component; 5, grinding and polishing: grinding and polishing the surface of the metal shell of the motor by using a grinding machine; sixthly, surface treatment is conducted, specifically, surface blackening operation is conducted on the outer side of the component; the parts are machined in a numerical control machining mode, the accuracy of the internal size can be guaranteed to the maximum degree, meanwhile, secondary machining is conducted on the curved surface connecting position, and an inner cavity can be smoother.

Description

technical field [0001] The invention mainly relates to the field of production and processing, in particular to a processing technology for stainless steel parts of power drive equipment. Background technique [0002] With the development of the times and technology, the requirements for power-driven equipment have become small and powerful. At the same time, the small size will make the internal parts of the equipment more compact, the gap between the shell and the internal working unit will become smaller, and the requirements for the inner cavity of the shell will be increased. Existing equipment shells are generally directly formed by cold rolling or casting, and the size requirements are difficult to meet the standard; and the cost of high-precision molds is extremely high. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned defects of the prior art, the present invention provides a processing technology for stainless steel parts of power drive equipment...
