using vacuum brazing or atmosphere-protected brazing.
PCD has good fracture toughness and good thermal stability, and is used in making geological drill bits.
Polycrystalline Diamond (PCD): They are normally made by sintering many micro-size single diamond crystals at high temperature and high pressure.This tool usually has the features of good chemical stability, small elastic deformation, but high brittleness, etc. Ceramic-bonded diamond tools: The tools' bonding material is usually glass and ceramic powder.They can usually be made to good processing precision. Plated diamond tools: These tools are made by fixing the diamonds onto the tool's base via electroplating method or via CVD (Chemical Vapor Deposition) method.
An example of this kind of tool is the resin-bonded diamond polishing pads used in the construction industry.
High wear resistance: Diamond grinding tools' change in dimension is small.This can decrease or avoid burns and cracks on the surface of the workpiece, and decrease the equipment's wear and energy consumption. High grinding efficiency, Low grinding force: Less heat will be generated by the hole in the grinding process.So when used as an abrasive, it has many obvious advantages over many other common abrasives.Īdvantages of diamond grinding tools ĭiamond can be used to make grinding tools, which have the following advantages: Diamond also has high strength, good wear resistance, and a low friction coefficient. These are much sought after by engravers of gems and are inserted by them into iron tools because they make hollows in the hardest materials without difficulty." Advantages ĭiamond is one of the hardest natural materials on earth much harder than corundum and silicon carbide. In Natural History, Pliny wrote "When an adamas is successfully broken it disintegrates into splinters so small as to be scarcely visible. 2.1 Advantages of diamond grinding tools.
