round blades

round blade is usually durable cutting performance is better, but the use of a long time will certainly have a certain degree of wear, and this kind of wear strength with the following key factors.

Fabrication Materials

round blade material hard wear resistance is good, but at the same time the lower the toughness. Hardness and toughness are opposite, which is also an aspect that needs to be improved. If it is graphite round blade, the material can choose better toughness.

surface coating

diamond coating round blade has the advantages of high hardness, good wear resistance and low friction coefficient, which is the ideal production method at present. However, the production cost is high, and the current domestic technology in this area is not mature enough. Graphite coated round blade is widely used and practical.

Therefore, if you want to reduce the wear of the round blade, you can give priority to the material and coating.
