What Are Common Problems with Carbide Cutting Tools?

The following problems often occur during the manufacturing and use of carbide cutting tools:

1. The cross-section texture of the workpiece is large: This may be caused by large machine tool vibration, unreasonable tool installation, uneven reference plane, uneven feeding force, excessive tool runout tolerance, etc.

2. The workpiece is burnt: This may be caused by factors such as too slow pushing speed, excessive tool intake that does not match the machine tool speed, severe blunting of the tool, unreasonable tool selection, and a mismatch between the tool angle and the processing material.

3. The tool fit is not tight and there is a gap: This may be caused by the fact that the tool is not adjusted properly, the gasket is not added properly, the tool selection is not matching, the tool installation is unreasonable, the design size of the tool is inconsistent with the actual manufacturing size, etc.

4. Mixing: In the semi-finished product stage, matrix powders of other brands are mixed in due to various reasons. This situation will affect the product quality.

5. Burrs: Burrs usually appear in the molding stage. Because there are gaps between the mold bodies, there will be similar protrusions at the edge of the blade during the production process.

6. Cracks: Cracks usually occur when the press grabs the alloy tool during the production process due to excessive force, which causes cracks to form around the clamping hole and create gaps.

7. Sticky boat (sticky material): This situation may be caused by residue or damage on the mold body during extrusion molding, resulting in the extruded batch of finished products having the same size pits or raised residues in the same part.

8. Dust: This situation usually occurs in CVD chemical coatings. If debris falls onto the surface of the alloy tool, it will affect the quality of the product.

9. Coating peeling: This situation may occur in PVD physical coatings and is often caused by the blade being too small or the target material.

10. Color difference: Color difference usually occurs after the alloy tool is coated, and it can be caused by various reasons.

The above problems will affect the performance and quality of carbide cutting tools, so they need to be strictly controlled and avoided during manufacturing and use. If you encounter the above problems, it is recommended to seek professional help and advice in time.
