Cutting wheels are widely used in machinery, automobiles, ships, metallurgy, chemical and other industries, and can also be used in modern residential and factory iron decoration and equipment repair. Glass fiber and resin reinforced bond material, with high tensile, impact and bending strength, widely used in the production of ordinary steel, stainless steel metal and non-metal blanking, excellent materials, exquisite technology to ensure the high cutting efficiency of different materials and the best economic effect.
Small size cutting wheel can be installed in the electric Angle grinder, large size cutting sheet can be installed in the profile cutting machine. The invention relates to a cutting plate type thickened explosion-proof resin grinding wheel, which is not easy to crack and explode in use and has high strength. It can be used for grinding and polishing various workpieces and cutting workpieces or materials. The grinding wheel body is composed of 3 ~ 10 elastic layers in thickness, each layer is 5 ~ 6mm thick, and the abrasive layer is distributed along the radial axis. The outer diameter of the wheel body is Φ200 ~ Φ400mm, the thickness is 15 ~ 60mm, and the inner aperture is Φ25 ~ 32mm. The elastic layer is glass fiber or nylon fiber filament-like sheet, the overall stability and strength are improved, the noise is reduced, the dust is reduced, the sense of security is enhanced, the wear resistance is greatly improved, the cost is low, the structure is simple, so it has a wide range of application prospects.
Cutting wheels are made of high-strength resin and preferred special abrasive, they allow large linear speed, more than 50 m/s, not easy to crack; The cutting is sharp, the cutting heat is minimal, and the sample heat affected layer is shallow, thus minimizing interference.
The grinding temperature of the ultra-hard cutting wheel is low, which can greatly improve the surface quality of the workpiece to be machined, and avoid the defects of the parts such as cracks, burns and tissue changes. It also greatly improves the stress condition of the machined surface of the parts, is conducive to the extension of the service life of the parts, and improves the comprehensive economic indicators. The ultra-hard cutting sheet has less wear, long service cycle, high grinding ratio, and good economic results can be obtained under the conditions of reasonable use, especially for materials that are difficult to process with ordinary abrasives.
In fact, the hardness of the cutting wheel is the main characteristic that determines the performance of the abrasive. Superhard abrasives themselves have extremely high hardness, so they can process a variety of high-hardness materials, especially materials that are difficult to process with ordinary abrasives. For example, the use of diamond abrasives to process cemented carbide and ceramics, agate, optical glass, semiconductor materials, stone, concrete and other non-metallic materials and non-ferrous metals; With cubic boron nitride grinding tools processing tool steel, die steel, stainless steel, heat-resistant alloy, especially the processing of high vanadium high-speed steel and other ferrous metals, can obtain satisfactory processing results
