Machining

Separate intermittent tool changes and clamping from blow-off and continuous uses. Describe the short peaks that an average meter reading can hide.

Before you buy

  • Which machine tools, fixtures and auxiliary devices use compressed air?
  • Which uses are tool changing, clamping, blow-off or continuous process air?
  • What air volume or flow does the maker specify per cycle, with cycle rate and flow basis?
  • Which events overlap, how long do peaks last and what sustained demand remains?
  • What minimum pressure is required at the most distant machine and at critical clamps?
Further points to confirm
  • What pressure dew point, filtration and oil limits are required by the machine maker?
  • What existing receiver volume, pipe dimensions, observed pressure changes and backup are documented?
  • A cycle-average flow is not the instantaneous flow during a tool change or blow-off.
  • A local pressure problem is not proof that the whole plant needs a larger compressor.
