coated abrasive  molding method according to the needs of different commonly used are the following : 1. Hydroforming
Hydraulic molding equipment hydraulic machines and hydraulic press , because oil has the proper viscosity, not prone to back and stable, so abrasive molding is generally used hydraulic machine ( Figure 1 ) without water presses, such as the use of appropriate structural hydraulic machine can have ease of lift . Allows ease of lifting the molding compound at the time of pressing the abrasive gases sufficient time to escape from the mold compound, and the material layer can have time to get up and down and reduce the wheel traverse uneven density , and reduced after moving the elastic effect, increasing the pressure to maintain a predetermined time to obtain better results ; this operation , but the lift is too slow , reducing productivity. Using high pressure into the rough can get a higher density . In the 1970s the country has a ring automatic molding machine, but it only applies to a single large production specifications , the SMEs do not apply. In recent years, domestic research on automatic molding machine has made significant progress in Figure 6 is the factory producing ceramic abrasive 18- station automatic molding machine.

In order to meet the requirements of different grinding the  coated abrasive  divided into three categories, namely, grinding wheel, grinding, Whetstone.
 Wheel with a flat, double bevel, single bevel, concave-sided, double-sided concave, convex-sided, cylindrical, cup, bowl, dish, etc. shape. There are cylindrical grinding, elliptical cone, round cone, spherical, hemispherical and mounted points and so on.
There are square Whetstone Whetstone, Whetstone rectangular, triangular stone, knife-shaped stone, cylindrical Whetstone, semicircle Whetstone. Abrasives may determine the shape of the above, the choice of what kind of wheels, mainly determined by the requirements of grinder models, the grinding wheel drive models and products. The selection of the wheel, that is what made abrasive abrasive, the effect is directly related to the use of the wheel.
