What are grinding wheels, cutting discs, and grinding discs? What is the difference between them?

Grinding wheel is a very common abrasive tool in the grinding process. It is usually made by adding a bonding agent to the abrasive, and then forming a compact, drying and roasting. Its characteristic parameters mainly include abrasive, viscosity, shape, hardness, and bonding. Agent, size, etc.

Because of the difference in abrasives, bonding agents and manufacturing processes, the final grinding wheel discs are also quite different. Therefore, abrasives, bonding agents and manufacturing processes have an extremely important impact on the quality and productivity of grinding.

According to the abrasive, the grinding wheel can be divided into ordinary abrasive (corundum and silicon carbide, etc.), natural abrasive super-hard abrasive and (diamond and cubic boron nitride, etc.) grinding wheels; according to the shape, the grinding wheel can be divided into flat Grinding wheels, cup-shaped grinding wheels, cylindrical grinding wheels, bevel grinding wheels, dish-shaped grinding wheels, etc.; according to the binder, the grinding wheel can be divided into metal grinding wheels, rubber grinding wheels, resin grinding wheels, ceramic grinding wheels, etc.

Cutting disc

Cutting disc refers to a thin sheet made of abrasives and binder resin for cutting ordinary steel, stainless steel metal and non-metallic materials. It mainly uses glass fiber and resin as a reinforcing bonding material, which has high tensile, impact and resistance. The characteristics of bending strength, so it is widely used in the production of ordinary steel, stainless steel and non-metallic materials.

According to the material, the cutting blades are mainly divided into fiber resin cutting blades and diamond cutting blades. Among them, the former uses resin as a bonding agent to combine glass fiber mesh with a variety of materials, which can realize the cutting of alloy steel, stainless steel and other hard materials. The performance is very significant, and the stability of the cutting accuracy is guaranteed, which can greatly improve the cutting efficiency. Save production costs. Its cutting methods are dry and wet. Diamond cutting discs are mainly used for cutting hard and brittle materials such as stone, new and old roads, precast slabs, concrete, and ceramics. It mainly includes two parts: the base body and the cutter head. The matrix is the main supporting part of the bonded cutter head, and the cutter head is the main tool for cutting. Because the cutter head contains diamond, as the hardest substance at present, diamond can effectively cut the processed object. The cutter head will be worn during use, but the matrix will not.

Polishing sheet

The grinding disc is to plant fine abrasive particles (alumina or silicon carbide) on the high-strength polyester film with the help of high-voltage electrostatic field force, so that all the sand particles are pointed out and the cutting is sharp, which can provide higher grinding efficiency and Bright and meticulous polishing effect, and then processed by backing and cutting.

The abrasive particles of the polishing pad are oriented and arranged, and the surface of the product is sharp, ensuring the best grinding performance of the abrasive belt; the surface of the product is evenly distributed, combined with a special binder, to prevent deep lines and irregular lines, and good chip removal ability , Not easy to block.

Disc sand is a kind of polishing pad. Disc sand is a round sanding sheet processed with sandpaper, which can be divided into two types: quilt and double-sided tape. It is used to polish hardware parts, plastics, and auto parts. It can be used faster than ordinary sandpaper. The grain number is divided into 60# 80# 100# 120# 150# 180# 220# 240# 320# 400#. The sanding sheet is used for sanding faster than ordinary sandpaper.
