The Breakage of Tungsten Carbide Blades – Causes and Solutions

Cracks and subsequent breakages are common issues with tungsten carbide blades. This article briefly identifies the 5 causes of potential breakages and solutions to extend blade life.

1) Incorrect Choice of Blade Specifications and Grades

Often, the blade is too thin or made of material that's too hard or fragile for the job.

Solution: increase the blade thickness or install it vertically. Seek expert advice to choose a material grade that is more resistant to toughness and bending.

2) Incorrect Tool Geometry Parameters

Improper geometry parameters can affect cutting efficiency.

Solution: grinding the cutting edge or modifying the cutting angle to ensure smooth operations.

3) Poor Maintenance

Using the blade for too long without proper maintenance can cause excessive wear.

Solution: schedule regular preventive maintenance or replace the blade as needed.

4) Incorrect Blade Installation

Improper installation can lead to cutting issues.

Solution: reinstall the cutting tools correctly. Consult an expert if there are doubts about proper installation.

5) Excessive Cutting Vibration

High vibration during cutting can damage the blade.

Solution: enhance auxiliary support to improve the rigidity of the workpiece, significantly reducing cutting vibration.

By addressing these points, the occurrence of blade breakages can be significantly reduced.
