Abstract

The invention discloses a precision ultra-precision machining method for forming grinding. Through the method, the precision progressive type grinding machining technology mode, including in-place shape correcting, in-place trimming, online electrolytic sharpening and online detection, of a metal-bonded grinding wheel is achieved. The method is characterized in that graphite wheel precision turning forming is achieved in place; deionized water serves as a medium, and grinding wheel electric spark precision forming and shape correcting are achieved; through a diamond roller opposite-grinding trimming method, in-place trimming of the grinding wheel is achieved, and a hard layer is removed; online electrolytic sharpening is conducted, and it is achieved that the good sharpness of the grinding wheel is kept all the time in the grinding and removing processes; online detection is conducted, and dimensional precision detection of a machined part is achieved; and according to the grinding wheel particle size, the concentration and progressive magnitude between different procedures, precision progressive type precision forming grinding machining is achieved. Through the precision ultra-precision machining method, the problems that a traditional machining mode is poor in offline shape correcting, trimming, sharpening, detection and machined surface quality, and the machining quality consistency is difficult to ensure are solved, and precision ultra-precision forming grinding machining can be achieved under the batch production conduction.

Description

technical field

[0001] The invention relates to a precision ultra-precision machining method for forming grinding, which belongs to the field of precision ultra-precision machining. Background technique

[0002] Forming abrasives in traditional processing have complicated and complicated processing procedures, and each process will accumulate processing and installation errors. In addition, due to fatal defects such as large size changes and serious wear and tear of the abrasives themselves, the processing efficiency is low, the surface quality is poor, and the processing quality is low. Consistency is difficult to guarantee. Surface quality and processing quality consistency will directly affect the performance and service life of parts. The metal bond grinding wheel has the advantages of high hardness, large grinding ratio, good shape retention, and not easy to wear.

[0003] At present, the traditional dressing method is difficult for its dressing process. Most of the m...
