The manufacturing process of PCD tools mainly includes two stages: ① Manufacturing of PCD composite sheet: PCD composite sheet is made of natural or synthetic diamond powder and binder (including cobalt, nickel and other metals) in a certain proportion at high temperature (1000~2000C), sintered under high pressure (50,000 to 100,000 atmospheres). During the sintering process, due to the addition o...

The word “diamond” in diamond tooling is not a metaphor. Actual diamonds are built into the surface of the tooling as an abrasive. It is considered as a super-hard material and has many advantages compared to many other abrasive. Diamond are used for very specific reasons: Hardness. As most of us learned in science class, diamonds are the hardest natural substance on Earth. This means that diamond...

Resin bond diamond tools use a resin bond to hold the diamonds to the tooling. The  resin of resin diamond tools is a plastic called phenol-formaldehyde resin or phenolic resin. This plastic resin is familiar to many people as the hard plastic used to make billiard balls and quartz countertops. Tools with resin diamond abrasives are made by combining powdered phenolic resin with industrial di...

Metal bond diamond tools use a metal bond to hold the diamonds to the tooling. The metal is typically a mix of powdered metals that may include iron, cobalt, nickel, bronze, copper, tin, silver, or tungsten. A metal bond is formed by sintering (heating and compressing) a mixture of diamonds and metal powder. Metal bond diamond tools have different properties depending on the mixture of metals sint...

The coating material of PCD tools must have high hardness and high wear resistance, as well as stable chemical properties. It is generally difficult for a single PCD tool coating material to have the necessary performance. Therefore, coating materials of hard PCD tool have moved from a single TiC and TiN to a new stage of developing multiple coatings. The newly developed PCD tool coating not only ...

       When you think of floors, terrazzo may not be the first option that comes to mind. For years, hardwood and tile have dominated the commercial flooring industry. Terrazzo is not the most common flooring system today but has become one of the most valuable flooring systems. Terrazzo is a kind of floor decoration, and it is widely used in our house. It is often us...

Diamond tools have the characteristics of high hardness, high compressive strength, good gain and wear resistance,etc. which can obtain high machining accuracy and machining efficiency in high-speed cutting. The characteristics of diamond tools are determined by the state of diamond crystals. In the crystal, the four valence electrons of carbon atoms form bonds according to the tetrahedral structu...

Environmental Friendly The problem of indoor environmental pollution should be more recognized, and the choice of floor materials should be non-toxic, harmless, and pollution-free as the basic bottom line. Among the floor materials, The formaldehyde pollution of artificial floors and harmful substances such as paint volatile organic compounds pose a great threat to human health. The radioactive co...
