  • To remove excessive chip accumulation use an air blast.
  • Cutting conditions are limited by machine power and material
  • When chips stick to the cutting edges (aluminium machining), rigidity. When the cutting width or depth is large, set Vc and fz

use a water soluble cutting fl uid. below the recommended values and check the machine vibration and spindle load.
