Problems solved by technology

[0002] The chrome-plated coating on the inner hole of the part is often encountered in the processing process, especially the deep hole grinding of the material 1Cr17Ni2 chrome layer coating is a difficult point in the processing. During the grinding process, the chrome layer is often partially processed, Affect the surface quality of parts, while re-chrome-plating and grinding chrome will increase the labor intensity of the operator, occupy equipment, and waste resources

Abstract

The invention discloses a method for machining a part through a deep hole chromium layer. Reasonable grinding process parameters are selected, the rotating speed n is equal to 2800-3400 / min, the feeding amount fn is equal to 0.1 mm / r, the cutting depth ap is equal to 0.002 to 0.005 mm, the sanding wheel consumption ration is 0.02 / piece, and the method has the advantages that aeronautical parts areall provided with inner hole chromium plating structures, base body part materials 1Cr17Ni2 are common materials, and selecting of reasonable grinding process parameters and tools is the most effective method for quality and efficiency improving in machining. A method for grinding machining of the chromium layer of a front conical wall assembly can be more widely applied, the program passes through factory acceptance review, batched trial production is carried out, the part can meet the related standard need, and delivery after 100% qualification is achieved. The program can be expanded to use in machining of similar parts.

Description

technical field [0001] The invention relates to the field of deep hole turning processing of 1Cr17Ni2 material and inner hole chrome plating coating, and in particular relates to a method for processing parts with deep hole chrome layer. Background technique [0002] The chrome-plated coating on the inner hole of the part is often encountered in the processing process, especially the deep hole grinding of the material 1Cr17Ni2 chrome layer coating is a difficult point in the processing. During the grinding process, the chrome layer is often partially processed, It will affect the surface quality of the parts, and at the same time, re-chrome plating and grinding will increase the labor intensity of the operator, occupy equipment and waste resources. Choosing reasonable grinding process parameters and tooling is the most effective way to improve the quality and efficiency of machining. Contents of the invention [0003] The purpose of the present invention is to solve the p...
