Characteristics and Use of PCD Insert
Artificial single crystal diamond was gradually developed after the 1950s. It is synthesized from graphite as raw material, added with a catalyst, and subjected to high temperature and ultra-high pressure. Artificial polycrystalline diamond (PCD) is a polycrystalline mat...Read more -
Precautions for cutting tools grinding
1.Cutting tools material Common tool materials in tool grinding include: high-speed steel, powder metallurgy high-speed steel, cemented carbide, PCD, CBN, cermet and other superhard materials. High speed steel tools are sharp and have good toughness, while carbide tools ...Read more -
Tool regrinding and recoating
Tool is one of the important parts in machining machine tools. With the development of science and technology, the tool has changed from the original alloy tool to the most commonly used coated tool. The regrinding and re-coating of cemented carbide and high-speed steel ...Read more -
Application of high-speed steel materials
HSS, High SpeedSteel, is a kind of tool material that I contact most when I enter the tool industry. Later, we learned that the high speed steel we used at that time should be called "ordinary high speed steel", and there are better properties than it, such as aluminum h...Read more -
Superhard tool material and its selection method
With the development of modern science and technology, more and more engineering materials with high hardness are used, while the traditional turning technology is not competent or can not achieve the processing of some high hardness materials at all. Coated carbide, cer...Read more -
Why are non-standard cutting tools important for cutting?
In the process of machining, it is often difficult to use standard tools for machining, so the manufacture of non-standard tools is very important for machining. The use of non-standard tools in metal cutting is often seen in milling, so this paper mainly introduces the ...Read more -
Application problems and treatment methods of double end grinding wheel
What problems will be encountered in the grinding process of the double-face grinder wheel? How should we deal with it? 1. CBN grinding wheel burns workpiece during grinding (1). The hardness of CBN grinding wheel is too high: replace the grinding wheel with appropriate ...Read more -
PCD cutting tools used in 3C industry
At present, PCD tools are widely used in the processing of the following materials: 1, Non-ferrous metals or other alloys: copper, aluminum, brass, bronze. 2, Carbide, graphite, ceramic, fiber reinforced plastics. PCD tools are widely used in aerospace and automotive industries. Because these two...Read more -
Production process of cubic boron nitride (CBN) tool
1. Purification method of raw materials Because WBN, HBN, pyrophyllite, graphite, magnesium, iron and other impurities remain in CBN powder; In addition, it and the binder powder contain adsorbed oxygen, water vapor, etc., which is unfavorable to sintering. Therefore, the purification method of r...Read more
