一.Diamond Series product descriptions Abrasive type, and variety and diversity of specifications, Tools of the shape and size of the selection should be based on the use of machine tools and machining of workpieces abrasive demands, can be achieved excellent results. 1. Size option Granularity to size, thickness, size of the thickness directly affect the surface roughness, and the abrasive grinding efficiency loss. Choose to seize the main, for the best size, in principle, is to meet the processing requirements of the surface roughness of the conditions, possible use of coarse granularity, this can increase efficiency and reduce grinding abrasive wear and tear.

Granularity	Carbide workpiece surface roughness		Grinding processes
	Resin bonding agent	Metal bonding agent
60#－120#	－－	1.0~0.4	Coarse grinding
120#－240#	0.4~0.2	0.8~0.2	Precision Grinding half
240#－W20	0.2~0.05	0.4~0.2	Precision Grinding
W20－W1	0.05~0.012	－－	Lapping

2.Bond choice The combination of different agents have different properties, according to the different processing targets, the selection of different bonding agent.

Bonding agent	Code	Major uses	Characteristics
Resin bonding agent	B	For carbide, glass, ceramics, stone knives and non-metallic semi-Ground, Ground	Abrasives Self-sharpening, and not easily blocked, fever small, easily finishing, polishing performance and wear and heat resistance but worse, not suitable for heavy-duty grinding
Metal bonding agent	M	For carbide, glass, ceramics, gem stone and other heavy-duty cutting, coarse grinding, finishing grinding, form grinding.	Combine high strength, good wear resistance, low consumption of abrasive, able to withstand greater loads, but since the sharp poor, Improper use of fever and plug.
Ceramic bonding agent	V	For various steel and iron the dry mill, it is more suitable for long-axis grinding and Screw	Performance between resin binder and metal bonding agent between commonly used to produce high-speed CBN grinding wheel.
