Coated abrasives are designed according to specific applications, and the backing, abrasive grains, adhesive, coating and special production process all depend on different applications.

How to select suitable coated abrasives products? After communicating with some coated abrasives suppliers (including ZHEGNZHOU BOSDI ABRASIVES CO.,LTD., Zhengzhou Feilaike Abrasive Materials Co., Ltd., Luoyang Xiwei Abrasives Co., Ltd., Zhengzhou Yayun Abrasives Co., Ltd., etc.), we should consider the following factors:

A. The material of the grinded workpieces:

There are many kinds of grinding materials, such as stainless steel, tool steel, construction steel, castings, forgings, aluminum, titanium, aviation material, glass, ceramics, wood material, organic glass, etc., but they have different grinding conditions respectively. In addition to their properties themselves, the selection for physical properties of abrasive grains is also important, such as the hardness, toughness, microstructure, heat treatment conditions and types, etc.

B. The use of pressure:

The grinding pressure can be divided into three types: high, medium and low. To understand the required pressure will contribute to the selection of abrasive grains.

C. The requirements for surface roughness:

The Ra or Rt value on the surface of workpieces is very important. On the applications about surface polishing and surface wiredrawing, people can make surface treatment such as polishing according to customer's requirements.

D. The requirements for product's shape and tolerance:

The conditions on the surface of workpieces and the shapes are particularly important for the selections of abrasive products, and the workpiece tolerance control is also one of the factors to consider.

E. The grinding speed and machine speed:

The grinding speed depends on the speed of machine spindle operation. The RPM and grinding speed both need for conversion.

F. The cooling conditions:

The selection for grinding coolant depends on the requirements of grinding workpieces.

G. The machine power:

The running power of machines can effectively control the grinding amount of workpieces. Selecting the optimization of MRR - material removal rate, speed, grinding depth and feeding will be helpful to choose more suitable coated abrasives, and at the same time, it also needs to consider the power requirements of machines.

H. Supports, fixture, pressure sleeve and contact wheel:

Supports, fixture, pressure sleeve and contact wheel are also different according to the types of materials. For example, fixture and contact wheel can effectively improve grinding pressure and the efficiency.
