Problems solved by technology

[0004] Due to the strict requirements on the production process of good nylon wheels, they generally rely on imports. At present, there is no polishing wheel that can effectively replace imported nylon wheels and resin fine-grained polishing wheels with good shape retention, low price, and fast grinding speed without burning the workpiece. piece

Abstract

The invention relates to a polishing wheel piece. The polishing wheel piece comprises butadiene styrene rubber, pine tar, stearic acid, alumina, resin powder, zinc oxide, an accelerant DM and an accelerant M. Meanwhile, the invention further provides a production method of the polishing wheel piece. The method includes the steps of weighing materials, mixing the materials, conducting forming and conducting vulcanization. A polishing wheel sheet abrasive produced through the production method is under 280 meshes and used for polishing automobile connecting rods and shock absorber pipes, the surface roughness Ra can be less than or equal to 0.05, the polishing wheel piece can effectively replace a resin fine-granularity polishing grinding wheel and has the advantages of having a high shape protection property, less in the number of maintenance times, short in grinding time, low in cost and the like, and the polishing wheel piece can not burn a workpiece in the use process. The polishing wheel piece can partly replace a nylon polishing wheel imported from Japan. Cost is effectively reduced.

Description

technical field [0001] The invention relates to a formula for replacing imported polishing wheels and a production method thereof, belonging to the field of mechanical accessories. Background technique [0002] The polishing wheel is a press-fit flat wheel, which is formed by pressing several polishing wheel pieces, and the outer surface of each polishing wheel piece is evenly coated with a layer of polishing oil. No separate oiling is required during polishing. It is simple in structure and easy to use. [0003] Nylon wheel is a kind of polishing wheel, also known as (Anlong grinding wheel, non-woven wheel, fiber wheel), strong cutting force, can partially replace the traditional cloth grinding wheel, sponge cloth wheel and rubber abrasive cloth wheel, and can cover the abrasive cloth belt. The left thick lines are very effective for fine removal and continuous repair of larger burrs of castings, and the lines are fine and beautiful after grinding, which can be used for m...
