The use of coolants or lubricants during aluminum CNC routing is beneficial but not always mandatory. However, its use can significantly improve machining performance and tool life. Coolant serves several important purposes in the machining process:

  • Heat Dissipation: Aluminum is a material that conducts heat efficiently. The heat generated during the CNC routing process will cause the tool temperature to increase, which will hurt tool life and machining accuracy. Coolant helps dissipate heat, preventing excessive tool wear and maintaining consistent cutting performance.
  • Chip Removal: Aluminum machining will produce fine chips. Effective chip removal helps prevent chip accumulation, which will affect cutting quality and tool life. Coolant helps wash away chips from the cutting area, ensuring a clean, smooth process.
  • Surface Finish: Proper cooling helps achieve a better surface finish on machined aluminum parts. It prevents the material from overheating, which can cause problems such as melting or smearing, resulting in poor surface quality.
  • Tool Lubrication: Coolant lubrication reduces friction between the cutting tool and the aluminum material, minimizing tool wear and ensuring smoother cutting operations.
  • Reduce Workpiece Distortion: Cooling the workpiece during machining helps minimize thermal expansion and contraction, thereby reducing the possibility of workpiece distortion.

While coolant can be beneficial, some CNC routers utilize high-speed machining techniques or specific tool coatings to reduce the need for coolant. In some cases, coolant-free dry machining may be possible, where cutting parameters, tooling, and machine settings are optimized for aluminum machining.
The decision to use coolant when CNC routing aluminum depends on a variety of factors, including the capabilities of the machine, cutting parameters, tooling, material thickness, and desired surface finish. Trying different cutting strategies and consulting with a machining expert can help determine if the coolant meets your specific aluminum machining requirements.
