Milling copper electrodes and aluminium materials without clogging

Copper electrodes

Due to the thermal sensitivity of copper materials, using the cutting tools incorrectly can cause warping and built-up edges on the tool. To avoid this, milling cutters with a specially adapted geometry are needed. Sharp cutting edges also ensure controlled chip formation and thus optimum results.

Challenge during machining:

• Milling of complex and filigree contours
  
• Small radii and deep cross pieces
• Precision and surface quality at the highest level

Aluminium materials

Depending on the requirements, different aluminium alloys are needed. When machining soft aluminium alloys, a number of points must be taken into account in order to obtain optimum results.

Challenge during machining:

• Different aluminium alloys are suitable to different extents for machining.
• Soft aluminium alloys tend to stick together and form built-up edges
• Ensure sufficient cooling during machining

Aluminium materials – Special requirements for cutting tools

• More
  Nano polished cutting edges increase the service life at highest feed rates. Close
• More
  Unequal chip pitches reduce vibrations. Close
• More
  The special symmetrical front shape allows the highest feed rates with the best process reliability at the helix during ramping and drilling. Close
• More
  Optimal chip transport due to large, finely ground chip spaces for HPC milling, grooving, roughing and finishing Close
