Method for using forming rollers high-efficiency process bearing channel cutting tool

Abstract

The invention provides a method which processes a bearing channelling cutter with high efficiency by adopting forming grinding, comprising (1) the cutter is designed according to the requirement of a bearing channel and structure and dimension of an electrode used for trimming a grinding wheel is also designed; (2) after the electrode is designed and manufactured, the electrode which is taken as a cathode and the grinding wheel which is taken as an anode are respectively arranged on an ELID trimming system; grinding liquid with electrolysis capability passes through the clearance between the external spherical surface of the grinding wheel and the electrode; under the action of a power supply and the anode solution effect of the electrolysis process, a metal basic body on the surface of the grinding wheel is removed by electrolysis; a metal binder of the grinding wheel which is taken as the anode generates the anode solution effect and is gradually removed and grinding grains which are not affected by the electrolysis are exposed on the surface of the grinding wheel, thus implementing online trimming of the grinding wheel; (3) the profile of the grinding wheel which is trimmed is taken as the anode which is trimmed by the ELID and a corresponding cutter is grinded on the ELID trimming system by taking the hard alloy as the cathode.

Description

Technical field [0001] The invention relates to an ultra-precision grinding technology, in particular to a high-efficiency, high-precision grinding technology for hard alloy material cutters. Background technique [0002] The bearing groove is the key working surface of the rolling bearing, and its surface quality directly affects the performance of the entire rolling bearing. Among them, the surface roughness of the inner and outer grooves is the main reason that affects the vibration of the bearing, so the requirements for the cutting tools for processing the bearing grooves are put forward. [0003] At present, the overall technology of bearing ultra-precision equipment in my country is still immature, and many companies are still using rolling rod soil equipment and the most primitive manual polishing process. The surface roughness, waviness, and vibration value of the processed bearing groove cannot reach the industry level Standard, low pass rate, low product precision...
