A kind of preparation method of diamond roller for dressing cbn grinding wheel with high efficiency

Abstract

The invention provides a high-efficiency diamond wheel preparation method for dressing CBN grinding wheels, which includes the following steps: S1: Take diamond particles and copper-iron alloy powder and put them into a micro mixer to stir to obtain mixed powder, add lubricant to the mixed material, and continue to stir Obtain the mixed material; S2: put the mixed material into a graphite mold, press it into a metal sheet, put it into an intermediate frequency sintering machine for sintering, and obtain a diamond alloy sheet after cooling; S3: process the roller base, put the diamond alloy sheet into high-frequency heating Heat in the machine, take out the diamond alloy sheet and put it on the roller base quickly, and get the diamond roller after cooling; S4: The diamond roller obtained in S3 is polished and then dynamically balanced, cleaned and dried, sprayed with anti-rust oil and packaged for storage. In a word, the invention has the advantages of novel method, convenient operation, low cost and long product life.

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...

AI Technical Summary

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.
