SCHUNK recommends that the user install a high-flow pneumatic pressure regulator and a high-flow valve to properly supply a stable air supply to the spindle motor (...
  • Page 22 13)). The compliance force, air supply pressure regulator should have a (FDB 150: 1.4 - 4.2 bar / FDB 300-1040: 0-4.1 bar) range. When testing for the proper contact force, start with a very low pressure and increase slowly until the desired cut is achieved.
