Factors affecting the wear of the circular blade
- Jan 05, 2019 -

Circular blades are usually very durable and have good cutting performance, but they will definitely wear to a certain extent after a long period of use, and this strength is related to the following key factors.


The round blade manufacturing material has good hard wear resistance, but at the same time the lower the toughness. Hardness and toughness are the opposite, and this is one aspect that needs improvement. If it is a graphite round insert, the material can be selected to have better toughness.

Surface coating

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

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