Electroplated diamond tools, grinding wheels improvements

Electroplated diamond tool holding force exists insufficient particle shedding and other issues, has seriously affected the tool life and efficiency. This paper reviews the recent development of domestic and step pads  electroplated diamond tool performance improvement methods , grouped into the following three categories: one , improving coating matrix material properties, improve the coating and bonding of the diamond supporting role ; 2 , by increasing the diamond and the the contact area of ​​the carcass , to eliminate the gap between the diamond and the coating ; 3 , the diamond particle surface treatment , the coating is formed between the diamond and the chemical bonding . The text of the various methods are described in detail , there is potential for some methods are recommended to readers of electroplated diamond tools, improved methods have a comprehensive understanding of the system  Because diamond has a high hardness, high strength, high wear resistance and low coefficient of linear expansion and a series of excellent physical and chemical characteristics, are used to produce diamond tools for machining hard and brittle materials difficult to machine . Electroplating diamond tools prepared by  wall saw blades electrodeposition of metal , the consolidation of loose diamond particles in the plating layer, and the diamond particles have a cutting ability . Electroplated diamond tool manufacturers prepared low temperature to avoid heat loss of the diamond , and the production process is simple , less investment in equipment , the manufacturing cycle is short, convenient shape and can repair. Therefore, electroplated diamond products have a variety of grinding wheel, grinding , needle files , dig riving knife , trim wheel , geological drill bits, reaming, and external circular cutting disc , reamers, wire saws and other special tools, machinery, electronics, construction, drilling , optical glass processing and other industries widely used [ ] .
At present, prepared at home and abroad with electroplated diamond tools , the main problem is that the coating matrix metal and the binding force between the diamond particles is low, the use of diamond  wet granite pads particles by force , it is easy to fall off , resulting in short life. The main reason for these phenomena is prepared by electroplating diamond tool manufacturing low temperature, resulting in the surface of the diamond particles are difficult for the general metal infiltration, instead of getting a strong chemical bond , and often a gap . In addition, by the impact of the plating process , an optional type coating metal diamond tools limited ( only nickel, chromium and other small metals and their alloys ) , unlike the hot-pressing tool type of metal used as widely .
To solve the above problem, people used a variety of measures to address the diamond and the coating metal binding force . This article describes the comprehensive recent development at home and abroad electroplated diamond tool performance improvement methods , and they were categorized , I hope to give people a detailed and clear understanding.
