What is Resin Grinding Wheel?

    Resin grinding wheel is a grinding wheel made of resin with high strength. It is used in cutting discs, double end faces, heavy duty grinding wheels, polishing wheels and so on. It has the characteristics of certain elasticity, low heat resistance, good self-sharpening, simple production and short process cycle; it is widely used in rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc.

    Resin grinding wheel is a grinding wheel made of resin, such as phenolic, epoxy, polyurethane, polyvinyl alcohol, etc.; resin grinding wheel has high strength, and can add reinforcing fiber mesh and steel bars to the grinding wheel, such as cutting discs, grinding discs, most of our The resin grinding wheel is not waterproof and cannot be ground with grinding fluid. Of course, there are also some resin grinding wheels that need to be ground with grinding fluid, such as epoxy resin. The grinding smoothness of the resin grinding wheel is good, and the workpiece is not easy to burn. The resin grinding wheel is used in cutting Disc, double face, heavy duty grinding wheel, polishing wheel, etc., the strength of resin bond grinding wheel is lower than that of metal bond and vitrified bond.

    Resin bond is an organic bond. The grinding wheel produced by this bond has high strength, certain elasticity, low heat resistance, good self-sharpening, simple production and short process cycle. Grinding wheels with working speeds higher than 50 m/s and very thin wheels can be manufactured. Its application range is second only to vitrified bond, and is widely used in rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc. It can manufacture high-speed, high-finish grinding wheels, heavy-duty, cutting and various special-required grinding wheels.

    At the same time, the resin-bonded grinding wheel is a tool that is in great demand. It is a tool made by bonding diamond or cubic boron nitride (CBN) abrasives with 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, external centerless grinding, grooving and internal grinding. It is an ideal grinding tool for superheat-resistant stainless steel, cermet, ceramics, glass, limonite, high-speed steel, alloy tools and many other new superhard materials. There are many types of special resin-bonded diamond grinding wheels for rapid cold cutting. These grinding wheels are particularly suitable for the grinding of carbide tools such as saws, cutters, drills, end mills, etc.

    In addition, these tools can be used for precision grinding of carbide dies, 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 for grinding high-speed steel, tool and die steel, and superalloys above FtRC50.

The cleaning method:

    In the production process, the emery wheel is used for grinding on the belt. Generally, the grinding wheel should be removed and cleaned after 5-7 days of operation. (There are polished rubber scraps on it, which are tightly attached to the emery surface after high temperature friction, so it is difficult to clean) Now we soak it in acetone for 2 hours, and then clean it with imported cleaning agent, the effect is very good, but it is not environmentally friendly and does not save energy .

Cleaning requirements:

    1. To be environmentally friendly, free of ketones, not halogenated hydrocarbons.

    2. Can not damage the diamond wheel.

Installation Instructions:

    Grinding wheels must be carefully checked and identified before installation. The steps to check and identify are:

    1. Check that the grinding wheel is the correct grade and that it matches the performance, shape and size of all selected grinding wheels.

    2. Check and identify the appearance and structure of the grinding wheel. Visually inspect the wheel for damage (or cracks). Grinding wheels that are visually damaged (or cracked) cannot be used. In addition, it is also required that both ends of the grinding wheel are flat, and there must be no obvious skew.

    3. Check and identify internal cracks in the grinding wheel. Hold the grinding wheel by hand, tap the grinding wheel with a wooden hammer to listen to the sound, the grinding wheel without cracks makes a crisp sound, and the grinding wheel with cracks makes a hoarse sound, which cannot be used.

    Resin grinding wheels are generally divided into ordinary resin grinding wheels and superhard resin grinding wheels according to the abrasive. Ordinary resin grinding wheel is a grinding wheel with white corundum, brown corundum, silicon carbide and other common abrasives 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 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 diameters of common cutting discs are 100, 125, 150, 200,. The diameters of common grinding discs are 150, 200, 250, 300, 400.
