Resin film with ceramic grinding wheel cutting a small wheel, super oil stone, plating wheel, resin grinding (grinding superhard and P) products, for investment in business, marketing is not difficult, most can be said cottage, investment small, employing less, covers an area of ​​small, simple process, which produce high quality products with stable quality, a certain degree of difficulty, only often visit customers, invest in research and development of new products, learn a lot of advanced technology, in order to become a real business workshop .

  Characteristics of the grinding wheel performance impact:

(1) Abrasive material:

Commonly used abrasive cutting wheels cut with brown jade (A), corundum (wA), black corundum (BA), black silicon carbide (c), etc. The most commonly used is corundum, because corundum have high hardness, toughness, grain Fengrui, applicability, and the price is lower than other abrasive characteristics. Corundum smelting reduction of their adequacy in the sub-level sand and two sand, mainly in the chemical composition: a sand content of Al2O3 ¡Ý 94.5; two sand Al2O3 content <94.5%; generally 85% so, and Fe2O3 content of 4 to 5%;

(2) abrasive grain size:

Common size is: 22 # -80 #, when cutting small size and low efficiency.

(3) Wheel Hardness:

Common hardness: P, Q, R; N, S; general use hard wheel to reduce wheel wear. The hardness number by the binding agent, forming density, firing temperature and firing time and other factors controlled.

(4) binder:

 Commonly used resin binders are: phenolic resin powder, liquid phenolic resin. Powdered phenolic resin technology is good, abrasive molding density of smaller, slightly larger number of organizations, the price is higher than the liquid phenolic resin; liquid phenolic resin prices are low, but easy caking materials and mixed material is not easy to spread evenly, easily lead to abrasive local hard.

(5) Organization:

Cutting wheel should be slightly larger number of organizations to improve cutting efficiency: too much will affect the strength, number of organizations have used 3 to 7.

Forming firing (also known as hardening) process on the cutting performance:
