Carbide Gear Cutter Made In China---114*19.69*15.24
Coating single-layer or multi-layer carbides, nitrides, oxides and other intolerant cemented carbide compounds on the surface of cemented carbide by physical, chemical, plasma vapor deposition and other methods can greatly improve the performance and performance of cemented carbide tools. service life. Coated cemented carbide has a series of advantages such as high room temperature and high temperature hardness, good oxidation resistance, crater wear resistance, small friction coefficient, low surface roughness of the workpiece, and long tool life. Therefore, the development of this type of alloy is extremely rapid, the variety and output of alloys are increasing, and the scope of application is expanding.
Coated cemented carbide has the following advantages:
The coating has high hardness (TiC-2800HV30, TiN-2100HV30) and good wear resistance, which can reduce the crater wear and flank wear on the rake face of the tool, and improve the tool durability.
The cutting speed of the coated insert is 25%-30% higher than that of the non-coated insert, and the insert life can be extended by 1-3 times at the same cutting speed.
It can reduce the phenomenon of knife sticking, and it is not easy to generate built-up edge.
The friction coefficient between the insert and the workpiece is small, which can reduce the cutting force by 10%-15%.
The same coated insert can be used for both finishing and semi-finishing and can replace two different grades of uncoated inserts.
