metal saw (coarse teeth) :
The cutting edge is around the outer circle and is used to cut or machine narrow grooves.

Process characteristics
The grains (carbides) in the microstructure are refined by air hammer repeated forging, so that the super red hardness and wear resistance of the metal can be improved. The super fatigue fracture resistance of high speed steel is developed at high rotational speed. Thus prolonging its service life and finally achieving the purpose of saving time and energy loss for customers.

Processing technology characteristics
The NC machine tool is used to grind the surface of the blade repeatedly, so that the surface finish can reach a high standard. At the same time, the imported micro-digital control machine tools are used to cut the blades (triangular edge and radial edge), and the products reach the same level of domestic leading level.

Heat treatment process: High speed saw blade: usually in1205～1215Salt bath quenching at °C, quenching tissue metallographic level10~11Stage, then step isothermal, hot clip, tempering4Second, the tempering process is not allowed to overheat, the final microstructure hardness64～66.5HRC.

Application of saw Blade Milling Cutte 
Mainly used for copper, iron, aluminum, alloys, and other medium hard below the narrow and deep metal material slot processing or cutting. At the same time, it can also be used for milling of non-metal materials such as plastics and wood. High nitrogen type or coated saw blade milling cutter should be used when cutting stainless steel.
