Application and introduction of cutting blade

Cutting discs are widely used in machinery, automobiles, ships, metallurgy, chemical industry and other industries, and can also be used in iron decoration and equipment repair of modern houses and workshops. Using glass fiber and resin as reinforced bonding material, it has high tensile, impact and bending strength, and is widely used in the production and blanking of ordinary steel, stainless steel and non-metallic materials. High cutting efficiency of workpieces and optimum economical results.

Small size cutting blades can be installed on electric angle grinders, and large size cutting blades can be installed in profile cutting machines. A cutting-piece thickened explosion-proof resin grinding wheel, which is not easy to crack and explode when used, and has high strength. It can not only be used for grinding and polishing various workpieces, but also can be used for cutting workpieces or materials. It is composed of 3-10 layers of elastic layers, each layer is 5-6mm thick, and the layers are abrasive layers with reinforcing ribs distributed along the radial direction. The outer diameter of the wheel is Φ200-Φ400mm, the thickness is 15-60mm, and the inner diameter is Φ25~32mm; the elastic layer is glass fiber or nylon fiber filamentary sheet, the overall stability and strength are improved, the noise and dust are reduced, the sense of security is enhanced, the wear resistance is greatly improved, the cost is low, and the structure is simple, so It has broad application prospects.

The cutting discs are all made of high-strength resin and specially-made abrasives, which allow a large linear speed, more than 50 m/s, and are not easy to be brittle; the cutting is sharp, the cutting heat is extremely small, and the sample heat-affected layer is shallow, so as to minimize the interference.

The grinding temperature of the super-hard cutting blade is low, which can greatly improve the surface quality of the workpiece to be processed, avoid cracks, burns, and tissue changes in the parts; extended, so that the comprehensive economic indicators can be improved. The superhard cutting blade has less wear, long service life and high grinding ratio. Under the condition of reasonable use, good economic effect can be obtained, especially for materials that are difficult to process with ordinary abrasives, the economic effect is better.

In fact, the hardness of the cutting disc is the main characteristic that determines the performance of the abrasive. Superabrasives have extremely high hardness, so they can process various high-hardness materials, especially materials that are difficult to process with ordinary abrasives. For example, diamond abrasives are used to process cemented carbide, ceramics, agate, optical glass, semiconductor materials, stone, concrete and other non-metallic materials and non-ferrous metals; cubic boron nitride abrasives are used to process tool steel, die steel, stainless steel, heat-resistant Alloys, etc., especially when processing ferrous metals such as high vanadium high-speed steel, can achieve satisfactory processing results.
