Supercut Solid Carbide Mills
Tip #3: Ball nose
When using a Ball nose End-Mills, the most critical
area of the cutting edge is the tool center. At that
point the cutting speed is close to zero which is not
recommended for the tool cutting.
Therefore, tilting the spindle or the workpiece
by 10⁰ to 15⁰ is recommended, which moves the
cutting zone away from the tool center.
This provides:
• Better chip evacuation
• Better surface finish
• Improved tool life
