Introduction and Analysis of Resin Grinding Wheel

Resin grinding wheel is a kind of resin abrasive product mainly made by chemical synthetic fabrics as increasing materials, which has higher tensile strength, impact resistance and flexural strength. Resin grinding wheel is often installed in electric and pneumatic polishing machine, and it can maintain all kinds of metal surface, clean up weld joint and solder joints, grind castings burr, repair surface defects and workpieces’ grooving and cutting work. Using resin grinding wheel has high efficiency and better safety, suitable for chemical industry, shipbuilding, machinery, automobile, construction and other industrial departments.

Resin grinding wheel is a kind of industrial product with strong manufacturing technique, and the mixing, molding, hardening, processing and other processes will all affect the quality of products.

A. The mixing process: The uniformity is the key, and the molding material should meet the following requirements: It should have uniform composition distribution; It can stay loose, but powder leakage is not allowable; It must make the materials evenly, with good formability.

B. The forming process: At present, what we are using most is rotating flattening institution, but due to the limitation of the rotating flattening institution, it has caused wrong operation of some operators in some manufacturing enterprises, such as uneven mixture distribution, position tolerances and bad static balance.

C. The hardening process of resin grinding wheel: This is the key production process, and problems that are easy to cause bad quality, there are two factors: One is the temperature difference of curing oven or calcining kiln is too big , and the other is improper furnace charging ways. If the temperature difference of hardening furnaces is too big, the hardening process for resin grinding wheel will not meet the specifications (hardening curve), and the hardening quality of grinding wheel will be not fully guaranteed.

D. The machining process (mostly in large diameter high thickness resin grinding wheel) : resin grinding wheel, especially for those that have large diameter and high thickness or strict requirements for size tolerance. They should carry on the processing after hardening, to ensure the geometry size and position tolerances of grinding wheel.

E. The production formula and process parameter of resin grinding wheel are applied mechanically.

In order to produce high quality grinding wheels, every manufacturer should be proficient in these manufacturing process, and some great grinding wheel manufacturers on iAbrasive.com are always pretty good in this respect. They are : EEMO Ceramic Materials Co.,Ltd., ZHEGNZHOU BOSDI ABRASIVES CO.,LTD., CIPIE(Henan)Import and Export Trade Co.,LTD. and Beijing Dongmao Glass Machinery and Tools Co., Ltd.
