The grain size of diamond grinding wheel should be one point coarser than that of the dressing grinding wheel, and the size of diamond particles should be close to the same, and the shape of diamond particles is approximately spherical. The commonly used particle size is 36# ~100#.

Peripheral Diamond Grinding wheels are used for indexable inserts grinding. Peripheral Diamond Grinding wheels for indexable inserts, must be of a high level of geometrical accuracy, with ability of significant material removal.
Grinding wheel size: D400*W12*X6, W20
Grinding inserts：CBN, SNGA two-edge
Equipment: HI-powerful Peripheral grinding machine HP400 PLUS

iamond powder is mainly used for grinding and polishing, the control of particle size is particularly important. As long as there are oversized coarse particles will cause workpiece scratches so that preceding operation come to naught. So the quality inspection of powder is an important link to ensure the quality of powder products.

Tool steel refers to a variety of carbon steel and alloy steel that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures.

Grain sizes for grinding tool steel are generally in the range 24-100 mesh.

Coarse grain izes are used for rapid rate of remo val, when grinding large workpieces, grinding softer materials or when the contact surface of the grinding whee is large. Fine grain sizes are used to oroduce high surface finish, when grinding hard materials or when the contact surface of the grinding whee is small. The surface smoothness of the ground part depends not only on the grain size of the grinding wheel. The sharpness of the wheel, the bonding material used and the hardness of th wheel also play a considerable part ir determining the surface finish produced.

1. Linear velocity of grinding wheel

The circumferential velocity of grinding wheel and parts can directly affect the grinding efficiency.

The grinding wheel linear velocity is generally between 30-40 m/s when grinding the surface of the outer circle coating.

When grinding the surface internal grinding, the grinding wheel linear velocity is generally between 18-28 m/s.

The linear speed of the workpiece is based on the size of its diameter, generally chosen between 25-40 RPM.

Different components:

1. CBN insert: Artificial cubic boron nitride cutting tool, at high temperature can also maintain the characteristics of high hardness, mainly for processing iron parts.

2. Ceramic insert: Metals or nonmetals combined with oxygen (O), nitrogen (N), carbon (C), and other elements are called ceramics. After sintering, it can be used as a cutting tool.
