CNC milling tool wear: Causes and repairs
As a leading five-axis CNC machining service provider, we understand the importance of keeping the best tool wear to ensure high-quality products and an efficient production process. CNC milling tools are worn due to various factors, which can lead to reduced performance, reduced life and increased downtime. In this article, we will explore common causes of wear of CNC milling tools and provide solutions to help mechanics and manufacturers overcome these challenges.
Causes of wear of CNC milling tools
- Inadequate cooling: Inadequate cooling during processing can cause tool overheating, resulting in accelerated wear. This is especially true for cutting tools made of thermally sensitive materials such as titanium or high-speed steel.
Solution: Improve the cooling system or using cutting fluid can effectively remove heat and debris from the cutting zone.
- Incorrect tool geometry: Using tools with incorrect geometry can lead to increased wear due to poor alignment, vibration or excessive cutting forces.
Solution: Check and adjust tool geometry to ensure proper alignment during machining and minimize vibration.
- Inadequate tool strength: Failure to select the right tool material or design may result in premature wear due to excessive cutting force or thermal stress.
Solution: Choose tool materials and designs that can withstand cutting forces and typical thermal stresses for machining operations.
- Poor tool maintenance: Ignoring regular tool maintenance can cause wear on the tool.
Solution: Check and maintain tools regularly to prevent wear and extend their lifespan.
- Material properties: Processing materials with high hardness, toughness or strength can cause excessive wear of the cutting tool.
Solution: Choose tools with enhanced functionality, such as coating or tilt tools, to improve wear resistance.
- Vibration and distortion: Vibration and distortion in the machine or workpiece can cause excessive wear of the cutting tool.
Solution: Implement measures to reduce vibrations, such as absorbing sound materials, and ensure proper machine alignment and maintenance.
