Resin bond is an organic bond. The grinding wheel manufactured by this bond has high strength, certain elasticity, low heat resistance, good self-sharpening, simple production and short process cycle. It can manufacture grinding wheels with working speed higher than 50 m/s and very thin grinding wheels. Its application range is second only to the ceramic bond, and it is widely used in rough grinding, barren grinding, cutting and free grinding, such as grinding steel ingots and burring castings. It can manufacture high-speed, high-finish grinding wheels, heavy-duty, cut-off and various special requirements.
At the same time, resin-bonded grinding wheels are a tool that is in greater demand. It is a tool made by gluing diamond or cubic boron nitride (CBN) abrasives and inorganic fillers using benzoic acid and polyamide or other resins as binders. This tool is being effectively used in various grinding operations, such as surface grinding, centerless grinding, slotting, and internal grinding. It is an ideal grinding tool for super heat-resistant stainless steel, cermet, ceramic products, glass products, limonite, high speed steel, alloy tools and many other new superhard materials. <BR> There are many kinds of special resin bonded diamond grinding wheels for rapid cold cutting. These grinding wheels are particularly suitable for grinding carbide tools (such as saws, cutting machines, drilling tools, end mills, etc.). In addition, these tools can also be used for precision grinding of cemented carbide molds, rollers and carbide wear parts. Resin bonded grinding wheels are the first choice for precision machining of ceramic products and for grinding tungsten carbide and thermal spray coatings on ceramic products. Resin bonded grinding wheels can also be used in combination with CBN to grind high-speed steel, tool and die steel, and super heat-resistant alloys above FtRC50. Resin grinding wheels are generally divided into ordinary resin grinding wheels and super hard resin grinding wheels according to abrasives. Ordinary resin grinding wheel is a grinding wheel with ordinary abrasives such as white corundum, brown corundum, silicon carbide as the main grinding component, and superhard resin grinding wheel is a grinding wheel with diamond or CBN as the main grinding component.
The most commonly used ordinary resin grinding wheels in the market are ordinary resin cutting discs and ordinary resin grinding discs. Common diameters are 100, 180, 230, 300, 350, 400, 500.
The super hard resin grinding wheel market mainly includes super hard resin cutting discs and super hard resin grinding discs. The diameter of common cutting discs is 100,125,150,200. The diameter of common grinding discs is 150, 200, 250, 300, 400.
