Diamond is the hardest material discovered today. The tools made of it have high hardness, wear resistance, and excellent thermal conductivity. They have been widely used in non-ferrous metal processing, non-metal processing, and other fields. Compared with ordinary abrasive grinding wheels, it has obvious wear resistance and high efficiency, high processing precision, good thermal conductivity, and long service life.
It can grind hard alloy, glass, ceramic, and other difficult-to-process materials efficiently, which is conducive to the evacuation of heat, avoids the phenomenon of workpiece burns, cracks, and block falling, improves the efficiency and quality of workpiece surface processing, and is a special tool for grinding hard alloy, glass, ceramic, gemstone, and other high-hardness and brittle materials.
It is especially widely used in the cutting of aluminum and silicon aluminum alloys such as automobile engine cylinder blocks, cylinder heads, gearboxes, and various pistons.
At present, there are many varieties of diamond turning tools, boring tools, milling cutters, etc., with different diamond mass fractions, particle sizes, binders, etc., and their use in automobile manufacturing, automated production lines, etc. has reached a high proportion.
Blue Diamond Grinding Wheel has become an irreplaceable core cutting tool, which can achieve high efficiency, high stability, and long life CNC machining of CNC machine tools. In addition, materials with hardness close to diamond hardness are usually called superhard materials. The application in tool manufacturing mainly includes two categories: diamond (PCD) and cubic boron nitride (CBN).
Blue Diamond Grinding Wheel has high hardness and good wear resistance and has high requirements for grinding quality. Generally, it cannot be sharpened by hand or ordinary tool grinder but should be sharpened by grinders, diamond grinding wheels, diamond grinding wheels, etc. specially used for sharpening superhard tools.
Blue Diamond Grinding Wheel is widely used in various sectors and fields of industry.
Types of Diamond Grinding Wheels
There are many types of diamond grinding wheels, which can be classified according to the binder, production process, appearance and shape, and grinding method.
Ceramic bond diamond is one of the most popular diamond grinding wheels due to its excellent characteristics such as strong grinding force and good heat dissipation. With the rapid development of high-speed grinding and ultra-precision grinding technology, higher requirements are put forward for grinding wheels. Metal bond grinding wheels are widely used due to their remarkable characteristics such as high bonding strength, good formability, and long service life.
Main classification and varieties of diamond grinding wheels
Metal bond diamond grinding wheels are mainly divided into three types according to different manufacturing methods: sintering, electroplating, and brazing. Among them, the process of electroplated diamond grinding wheels is relatively simple, easy to manufacture, and the speed can be as high as 250-300m/s, but the heat dissipation is poor and the working layer is easy to peel off.
The new brazing technology diamond grinding wheel realizes the chemical metallurgical bonding of diamond abrasive grains, brazing binder, and metal matrix interface, breaking the constraints of traditional grinding wheel binder on the physical packaging of abrasive grains, improving the holding strength of brazed diamond grinding wheel abrasive grains, maintaining the climbing height of brazing binder at 20-30, and the exposure of diamond grinding wheel abrasive grains is as high as 70%-80%, making the grinding wheel sharper and greatly improving the cutting performance.
The grinding force, grinding temperature, grinding power, and grinding ratio generated during the grinding process can be greatly reduced, greatly improving the processing efficiency and the life of the brazed grinding wheel.
The brazed grinding wheel has sufficient chip space and can accommodate more coolant at the same time. It is not easy to block and can effectively reduce the temperature of the grinding workpiece to avoid burns and other phenomena.
