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 certain elasticity, low heat resistance, good self-sharpening, easy production, and short process cycle; it is widely used for rough grinding, barren grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc.
Resin grinding wheels are grinding wheels made of resin, such as phenolic, epoxy, polyurethane, polyvinyl alcohol, etc.; resin grinding wheels have high strength and can add reinforcing fiber mesh and steel bars, such as cutting discs, grinding discs, and most of us 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. The resin grinding wheel has good grinding smoothness and the workpiece is not easy to burn. The resin grinding wheel is used in cutting Discs, double-end faces, heavy-duty grinding wheels, polishing wheels, etc. The strength of resin bond grinding wheels is lower than that of metal bond and ceramic bond.
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.
In the production process, emery wheels are used to polish the belt. Generally, the grinding wheel should be removed and cleaned after 5-7 days of operation. (There are polished rubber crumbs on it, which adhere tightly to the surface of the emery after high temperature friction, and it is difficult to clean) Now we soak in acetone for 2 hours and then clean it with imported detergent. The effect is very good, but it is not environmentally friendly and energy-saving . Cleaning requirements: 1. To be environmentally friendly, free of ketones and not halogenated hydrocarbons. 2. Don’t damage the diamond wheel
The grinding wheel must be carefully inspected and identified before installation. The steps of inspection and identification are: 1. Check whether the grade of the grinding wheel is correct and whether it meets the performance, shape and size of all selected grinding wheels. 2. Check and identify the appearance and structure of the grinding wheel. Use your eyes to observe whether the appearance of the grinding wheel is damaged (or cracked). Grinding wheels with appearance damage (or cracks) cannot be used. In addition, both ends of the grinding wheel are required to be flat without any obvious skew. 3. Check and identify the internal cracks of the grinding wheel. Hold the grinding wheel in your hand and tap the grinding wheel with a wooden hammer to listen to the sound. The grinding wheel without cracks emits a crisp sound, and the grinding wheel with cracks has a hoarse sound, which cannot be used.
