Thanks to CNC technology, it is possible to work with advanced materials, which would otherwise be virtually impossible. This allows for the manufacture of complex, strong, and durable parts without compromising costs or delivery times.
TECHNICAL MATERIALS YOU CAN MACHINE WITH A CNC MILL:
- Aeronautical aluminum.
- Titanium.
- Stainless steel.
- Engineering plastics (such as PEEK, Delrin, or PTFE).
- Composites (carbon fiber, fiberglass).
- Brass and copper.
- Special alloys (such as Inconel or Hastelloy).
Let’s review some tips on CNC milling, which you can learn more about during the training we provide along with the installation of our milling machines:
WHAT TYPES OF MILLING ENDERS ARE MOST RECOMMENDED FOR THESE MATERIALS?
- Solid carbide end mills: Ideal for high-precision and hard materials.
- TiAlN or AlTiN-coated end mills: Improve heat and wear resistance.
- Polycrystalline diamond (PCD) end mills: Perfect for composites and engineering plastics.
- End mills with chip breakers and special geometries: Improved chip evacuation in steels and difficult-to-cut alloys.
TECHNICAL RECOMMENDATIONS FOR EFFICIENT MACHINING:
- Cutting speeds (Vc): Adapt the speed according to the material (e.g., higher for aluminum, lower for titanium or Inconel).
- Feed per tooth (fz): Start with conservative values and adjust according to chip behavior and stability.
COOLING:
- With aluminum and plastics: Liquid coolant or compressed air.
- With stainless steels or titanium: Abundant cooling with emulsion or soluble oil to prevent overheating.
- With composites and PEEK: Dry machining or with minimal lubrication to prevent delamination.
DEPTH OF CUT:
- Avoid excessive loads: It is better to make several passes with a shallower depth to preserve the tool.
