The invention discloses a device and method for ultra-precision forming and grinding of bearing rails, and belongs to the technical field of ultra-precision machining. The device mainly comprises a grinding wheel spindle module, a rotary workbench module, a grinding wheel electric discharge machining in-place shaping module, a diamond rolling wheel in-place shaping module, an ELID precision grinding module, a cooling and filtering module, an on-site detection module, an automatic feeding and discharging module and a control system module. The device and the method have the advantages that an ELID precision grinding technology is combined with the structural design of a multi-spindle rotary table type grinding machine, a modular design concept is adopted, semi-finish machining and finish machining of the high-precision bearing rails and on-line shaping and on-line dressing of a grinding wheel can be realized in the clamping process at a time, machined workpieces are subjected to on-sitedetection, and therefore the machining precision, the machining efficiency and the machining consistency of parts can be guaranteed.
Description
technical field [0001] The invention relates to an ultra-precision forming grinding processing device and method for bearing rails, belonging to the technical field of precision ultra-precision machining. Background technique [0002] At present, most of the bearing track processing technology mainly uses resin bond grinding wheel grinding and oil stone grinding as the main processing methods. There are fatal problems of large size changes and serious wear and tear of the grinding tools (resin bond grinding wheel and oil stone) during processing. Defects, which make it difficult to guarantee the machining accuracy and surface quality consistency. It directly affects the performance and service life of parts, becomes a bottleneck in the development of my country's bearing manufacturing industry, and seriously affects the competitiveness of my country's bearing products in the international industry. [0003] The ultra-precision mirror grinding technology of on-line electroly...
