Cutting fluid (metalworking fluid) is one of the most critical factors directly affecting tool life. When selected and used correctly, it reduces tool wear, controls heat, and stabilizes the cutting zone.
1. Reduces Wear by Decreasing Friction
- Cutting fluid forms a thin film between the tool and the workpiece
- Reduces direct metal-to-metal contact
- Delays abrasive wear
Result: the tool remains sharp for longer
2. Prevents Thermal Wear by Controlling Heat
- Dissipates high heat generated during cutting
- Prevents tool overheating
- Reduces the risk of hardness loss and micro-cracks
Especially critical for high-speed machining
3. Prevents Chip Adhesion (Built-up Edge)
- Lubricating effect reduces chip adhesion to the cutter
- Provides cleaner cuts
- Preserves the cutting edge geometry
4. Improves Surface Quality
- Achieves a smoother surface
- Reduces vibration and friction
- Prevents irregular tool loading
More stable cutting = longer tool life
5. Prevents Corrosion and Oxidation
- Forms a protective film on the tool surface
- Reduces rust and oxidation
- Especially important in water-based systems
6. Correct Oil Selection Determines Tool Life
- Oil-based cutting oils: high lubrication → longer tool life
- Water-based cutting fluids: high cooling → advantage in high speed
Incorrect selection can severely shorten tool life
7. Effect of Maintenance and Concentration
- Low concentration → insufficient lubrication → rapid wear
- Dirty fluid → abrasive effect → tool damage
- Regular filtration → more stable performance
