Suggested grinding feed rates for tct saw blades:

Feed ratio of hook angle surface to back relief angle is 1: 3

Saw blades need to be properly ground to ensure normal service life. Improper grinding, such as grinding only the hook surface or only the back relief angle, will reduce the number of grinding operations, thereby reducing the service life of the saw blade. In addition, it is necessary to ensure that the entire wear area is covered. Due to the different accuracy of the equipment, we do not recommend manual grinding of the saw blade. Automatic grinding equipment can ensure the accuracy and consistency of the two side angle. The simultaneous grinding of the two side can ensure the sharpness and stable service life of the carbide tooth. When the thickness of the tooth is less than 1mm, it is not recommended to re-grind for safety production considerations.
