A kind of preparation method of screw rotor cbn electroforming grinding wheel

Abstract

The invention discloses a preparation method for a CBN electroformed grinding wheel for a screw rotor. The preparation method comprises the steps of 1, earlier-stage processing of CBN abrasive material, wherein the CBN abrasive material is washed to be neutral through strong-base scouring agents and strong-acid scouring agents; 2, base body processing; 3, sand implanting in a base body through special equipment; 4, thickening on the special equipment after completion of sand plantation; and 5, later-stage dressing. The preparation method has the advantages that the earlier-stage processing technology of the CBN abrasive material is adopted, the surface of the CBN abrasive material undergoes the impurity removal treatment, the surface activity is improved, and coatings are firmer; in the sand implanting technology and the thickening technology, the specially-designed equipment is adopted, the base body rotates through the vibration effect generated by a vibration motor in the sand implanting process, fluid of the CBN abrasive material is uniformly implanted into the surface of the base body, the CBN abrasive material is attached to the surface of the base body more closely through the vibration effect, and the strength is far higher than that of common rotation modes; in the thickening process, the shape of the grinding wheel can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of grinding wheel manufacturing, in particular to a preparation method of a CBN grinding wheel, which is suitable for an internal core component of an air compressor, a male and female rotor, an automobile gearbox, and a wind power variable pitch yaw reducer gear. Background technique [0002] The internal core components of the air compressor, the male and female rotors, the automotive gearbox, and the gears of the wind power variable pitch yaw reducer are all made of high-strength materials, which are very difficult to process. The existing processing methods generally use different grinding wheels for processing, and the processing efficiency is low. The grinding wheel needs to be dressed in real time, and the grinding wheel is generally imported, and its preparation method is unknown. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention ...
