A kind of preparation method of grooved cbn electroforming grinding wheel

Abstract

The invention discloses a preparation method for a grooved CBN electroformed grinding wheel. The method comprises the following steps that 1, early-period treatment of a CBN grinding material is conducted, specifically, strong alkali washing agents and strong acid washing agents for the CBN grinding material are added, and the CBN grinding material is washed till being neutral; 2, a substrate is machined; 3, abrasive grains are dispensed on the substrate through specific equipment; 4, the substrate obtained after abrasive grain dispensing is thickened on the specific equipment; and 5, later-period trimming is conducted. The preparation method has the advantages that the early-period treatment process for the CBN grinding material is adopted, the surface of the CBN grinding material is subjected to impurity removal treatment, the surface activity is increased, and a cladding layer is firmer; in the abrasive grain dispensing and thickening processes, the specific equipment is adopted; in the abrasive grain dispensing process, the vibration effect generated by a vibration motor makes the substrate rotate, the effect that the CBN grinding material flow is evenly implanted in the surface of the substrate, the CBN grinding material tightly adheres to the surface of the substrate due to the vibration effect, and the intensity is much larger than that of an ordinary rotary mode; and in the thickening process, the shape of the grinding wheel can be ensured.

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, especially when slotting. The existing processing The method generally uses different grinding wheels for processing, the processing efficiency is low, and the grinding wheels need to be dressed in real time, and the grinding wheels are generally imported, and the preparation method is unknown. Contents of the invention [0003] In order to solve the above-mentioned technical prob...
