Thin carbide inserts have extremely high wear resistance. Correct use can better improve the cutting effect and extend the service life of the insert. Otherwise, it can easily 

cause the insert to break. Operators should pay attention to the following matters when using carbide thin inserts.

  Determine the accuracy level of the equipment to match the carbide thin insert. Check the accuracy level of your own equipment.

  Because cemented carbide is a superhard material second only to diamond in hardness. Carbide thin cutting tools have high hardness and high wear resistance, but at the 

same time they have poor toughness. It is easy to be brittle if it is improperly stressed or collided during operation, so the accuracy of the equipment must be carefully 

checked before use. In particular, the four parts directly related to the hard thin insert: the insert mounting flange, the paper support, the grinding wheel equipment 

(including bearings), and the insert lubrication device (part of the equipment) should be strictly checked to see if there is any looseness or Jumping phenomenon. Otherwise, 

it must be replaced or repaired before installing the insert.

 Install the insert

1. Check whether the tool holder has axial and radial runout; whether the tool holder bearing is damaged; whether the clamping surface is flat. (The knife installation surface 

should not be high on the inside and low on the outside) Otherwise, it should be repaired before installing the knife.

2. Check whether there is any foreign matter on the cutter disc, and wipe it clean before installing the insert.

3. When installing the insert, the inner hole of the insert and the axis should not be too tight. The insert must be clamped in place and tightly attached to the flange. 

Otherwise, the insert will be easily broken when the flange cover is tightened with screws. When tightening the insert bolt, it should be tightened at the angle, the force 

should be even, and the tightness should be appropriate.

4. Some thin insert machines (slitting and creasing machines) are equipped with a lubrication system. The insert must be placed in the center of the lubrication groove. 

The insert should be away from the lubrication center. There should be gaps on both sides of the insert and the lubrication groove. It is strictly forbidden to use the insert.
