Application Examples
Alumina (Al₂O₃), zirconia (ZrO₂) and silicon nitride (Si₃N₄) ceramic cutting tools are suitable for different processing scenarios due to their different physical and chemical properties. The following are their application examples.
- Alumina ceramic cutting tools: Finish turning of brake discs (cast iron).
- Zirconia ceramic cutting tools: Intermittent turning of stainless steel exhaust pipes.
- Silicon nitride ceramic cutting tools: High-speed milling of engine blocks (cast iron).

High-quality Service for You
Jinghui’s ceramic cutting tools are of excellent quality and can improve the dimensional accuracy of your products to 0.001 mm. With strict quality control, global delivery and professional technical support, we can optimize your industrial processing efficiency. Work with us to get tools that exceed your expected performance.
Ceramic tools offer higher hardness, heat resistance, and longer lifespan, reducing downtime and tool replacement costs in high-speed machining.
Cast iron, high temperature alloys (nickel-based/titanium alloys), hardened steel, composite materials and non-metals such as graphite and ceramics. Soft metals such as aluminum and copper (easy to stick to the cutting tool) are not recommended.
The main reason is vibration or excessive feed.
Suggestions:
1. Improve the rigidity of the machine tool.
2. Reduce the radius of the tool tip.
3. Avoid sudden changes in axial force during intermittent cutting.
