The characteristics of the grinding disc meet the requirements of ordinary users.
An grinding disc is a resin abrasive made of a special fiber fabric as a reinforcing material. It has high tensile strength, impact resistance and bending strength. It is a tool for grinding, grinding and polishing. Most of the abrasive tools are artificial abrasives made of abrasive plus binder, and natural abrasives directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of food processing, paper industry and non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood.

Angle grinding sheet production process: The modern production angle grinding sheet is basically a fully automatic production line, ensuring the stability of the product in a constant temperature and humidity production environment. Angle grinding sheet material selection: angle grinding sheet We pay great attention to the selection of materials, our preferred resin, high-quality abrasive and high-strength mesh, to ensure the cutting performance and safety of the product. Angle Grinding Product Features: We have been building the best products to meet the general cutting requirements of ordinary users.
The general principle for selecting the hardness of the grinding disc is to prevent the abrasive from falling off prematurely when processing the soft metal. When the hard metal is processed, new abrasive grains with sharp edges and corners are exposed, and the grinding disc is a soft grinding wheel. The working abrasive wear of the grinding wheel is very slow, the latter is because the working abrasive grains of the grinding wheel wear faster when grinding hard materials. In the case of fine grinding, in order to ensure the grinding accuracy and roughness, a slightly harder wheel should be used. When the workpiece material has poor thermal conductivity and is prone to burns and cracks (such as grinding hard alloys), the selected grinding wheel should be softer.

Because the grinding disc requires high-speed operation, it must be visually inspected before installation, and there should be no cracks. When installing the grinding disc on the grinding machine, pay special attention to it because the rotation speed of the angle grinding piece is very high, and if it is improperly installed, there is a danger of accident due to cracking. Before installing the grinding disc, first check the selected grinding disc for cracks. This can be observed or tapped with a wooden stick. For example, a person who makes a crisp sound is a cracker, and a cracked corner grinder should be absolutely prohibited. When installing the angle grinding piece, do not overtighten between the inner hole of the angle grinding piece and the outer corner of the grinding disc shaft or the flange, otherwise it will be thermally expanded during grinding, which will easily cause the angle grinding piece to burst: it should not be too loose, otherwise It is easy to eccentric, lose balance, and even vibrate. Generally, the clearance is 0.1-0.8 mm, and the clearance of the high-speed angle is smaller.
