High precision ceramic cutting inserts optimised for CNC machining
Product Highlights
✅ Super hardness: made of zirconia (ZrO₂) or silicon nitride (Si₃N₄) ceramic, the hardness is as high as HRA 90+, the wear resistance is far more than that of cemented carbide inserts, which is suitable for high-speed finishing.
✅ High Temperature Resistance: Ceramic inserts can maintain stability at temperatures above 1000°C, reducing coolant dependence and making them suitable for dry cutting.
✅ High Finish: Sharp cutting edge design effectively reduces burrs, suitable for high-precision turning and milling, especially for hardened steel, cast iron, high-temperature alloys and other difficult-to-machine materials.
✅ Ultra-long life: excellent anti-wear performance, insert life is 3-5 times longer than traditional carbide, reducing the frequency of tool change and improving productivity.
✅ Chemical inertness: no metal bonding phase, avoiding reaction with the workpiece material, ensuring pure and pollution-free machining surface.
Applicable machining scenarios
🔹 Hardened steel (HRC 50+): ideal for finishing high hardness materials.
🔹 Cast iron/high-temperature alloys: heat-resistant, suitable for aerospace and automotive parts machining.
🔹 High-silicon aluminium alloys: avoids tool sticking and improves surface finish.
🔹 Dry cutting/high speed machining: reduce coolant use, more environmentally friendly and efficient.

Recommendations for use
⚠ Avoid intermittent cutting: ceramic inserts are highly brittle and not suitable for strong impact conditions.
⚠ Recommend stable clamping: ensure machine rigidity and reduce the effects of vibration.
⚠ Dry cutting or light lubrication: reduces thermal shock and prolongs insert life.
