What are the influencing factors of the wear strength of the round blade?

The round blade is usually strong and durable, with good cutting performance, but there will be some wear after a long time, and this wear strength is related to the following key factors.

　　Manufacturing materials

　　The hard material of the round blade has good wear resistance, but the lower the toughness. Hardness and toughness are opposite, which is also an aspect that needs to be improved. If it is a graphite round blade, the material with better toughness can be selected.

　　Surface coating

　　Diamond coated round blade has the advantages of high hardness, good wear resistance and low friction coefficient. It is an ideal manufacturing method at present. However, the production cost is high, and the domestic technology in this field is not mature enough. Graphite coated round blade is widely used and has strong practicability.

　　Therefore, if you want to reduce the wear strength of the round blade, you can give priority to materials and coatings.
