The grinding stone is a general term for a small handle grinding tool, it has many kinds.
Ceramic grinding stone: Granular sand (usually corundum, white corundum, chrome corundum, silicon carbide) made of ceramic binder sintering, the central supplemented by metal handle. Mainly grinding all kinds of metal, for the inner diameter of the grinding, dressing the mold.
Rubber grinding stone: select the smaller size of the abrasive, the combination of rubber binder, used to polish the mold.
Abrasive cloth grinding stone: multi-piece rectangular abrasive cloth, bonding around the metal handle. Particle size is generally in the 60 # -320 #, used to polish the inner wall of the aperture.
Superhard material grinding stone: including the matrix and a number of grinding body, in which a number of grinding fluid clearance in the matrix fixed in the grinding surface of the grinding surface grinding body also set the gap, it has a high grinding performance, simple manufacturing And low cost, high quality grinding and can be applied to the characteristics of large-scale grinding.
In our mechanical hardware, molds, and related holes, groove processing, the role of small grinding stone can not do not care, in the actual grinding according to the material of the product depends on what kind of abrasive grinding stone, generally in Ordinary product grinding with corundum, silicon carbide, diamond, boron nitride abrasive mainly made. There are many shapes, such as: oval, truncated cone, 60 degree cone, elliptical cone, round cone, hemisphere, spherical and so on. Different purposes of the use of different grinding process program and its grinding head structure.
Diamond grinding stone with cutting sharp, high grinding efficiency, grinding wheel self-sharpening, processing workpiece surface roughness is low, less heat, no burns and other characteristics of the workpiece for a variety of hard alloy, ceramics, glass, jewelry, mold , Precision grinding tools.
The purpose of the diamond grinding stone:
Grinding the hole and other grinding wheel can not wear the place are indispensable it, mainly for grinding, polishing, grinding purposes.
At the same time according to the above characteristics of the diamond, according to the material can be divided into grinding for high and hard alloy, non-metallic materials. In this regard, the use of diamond grinding head compared with ordinary grinding wheel, unique, it is high hardness, high compressive strength, good wear resistance, diamond grinding head in the grinding process, a hard and brittle materials and hard quality alloy the best tool to use it to grinding the workpiece is not only efficient, high precision, and good roughness, grinding wheel less consumption, long life, but also improve working conditions. Therefore, it is widely used in ordinary grinding wheel is difficult to process the low iron content of metal and non-metallic hard and brittle materials, such as cemented carbide, agate gem, high alumina porcelain, optical glass, semiconductor materials, stone etc。
CBN abrasive as a good substitute for diamond abrasive, you can process the traditional abrasive can not be processed and difficult to process high hard and tough materials.Such as hardness of HRC65 various types of hardened steel and hardened cast iron, which can be exempted from the power consumption of annealing processing; and therefore also improve the hardness of the workpiece to extend the life of machinery and equipment; CBN grinding stone not only for high hardness materials, coarse, fine grinding, but also for milling, planing, intermittent cutting and other impact of a large processing; CBN abrasive durability than the traditional abrasive several times or even several times, reducing the number of tooling in the processing to ensure that the workpiece is small taper and high precision; can be high-speed cutting or to achieve " Cutting efficiency than traditional abrasive 3-10 times higher, to save time, electricity, machine number 30-70% or higher effect.
