Problems solved by technology

[0004] Today's factories are developing towards the pursuit of production capacity and quality, high precision, labor saving, lowering the technical threshold for operators, and removing the cumbersome operations in the middle. For CBN grinding wheel dressing, the previous process single-point diamond dresser cannot be used here. , because the consistency of the dressing is poor, the angle of the dressing has to be adjusted repeatedly. Since there is usually only one diamond, it wears quickly, the consistency is poor, and it cannot meet the special requirements of high precision. It is also frequently replaced, which is laborious and has a high rate of defective products.

Abstract

The invention provides a preparation method of a diamond roller for efficiently trimming a CBN grinding wheel. The preparation method comprises the following steps that S1, diamond particles and copper-iron alloy powder are taken and put into a micro stirrer for being stirred to obtain mixed powder, a lubricant is added into a mixture, and continuing stirring is carried out to obtain a mixture; S2, the mixture is put into a graphite mold, the mixture is pressed into a metal sheet, put into a medium-frequency sintering machine for sintering, and is cooled to obtain a diamond alloy sheet; S3, aroller base body is machined, the diamond alloy sheet is put into a high-frequency heating machine to be heated, the diamond alloy sheet is taken out and rapidly sleeves the roller base body, and thediamond roller is obtained after cooling; and S4, the diamond roller obtained in the S3 is polished, dynamic balance is carried out, cleaning and drying are carried out, antirust oil is sprayed, packaging and storing are carried out. In conclusion, the preparation method of the diamond roller for efficiently trimming the CBN grinding wheel has the advantages of novelty, convenience in operation, low cost, long product service life and the like.

Description

technical field [0001] The invention belongs to the technical field of new material preparation, and in particular relates to a method for preparing a diamond roller for dressing a CBN grinding wheel with high efficiency. Background technique [0002] Diamond roller is a new generation of grinding wheel dressing tool, which has the characteristics of high precision and high forming. CNC form grinding technology is a new type of processing technology that has developed rapidly at home and abroad in recent years. Its high-efficiency and precise processing methods have extremely wide applications in mechanical engineering. This article is based on the great and wide application prospect of grinding technology, and the background that there are still some limitations in the current grinding wheel dressing technology. [0003] The working principle of the diamond roller is: by installing it on the dressing device of the grinding machine, the diamond roller trims the ordinary cer...
