The machine requires the compressed air for the following tasks:

  • For the opening and closing of the collet chuck during tool changes.
  • For the spindle sealing air which prevents foreign bodies from entering the spindle.
  • For the sealing air in the working chamber that keeps machining debris away from sensitive machine parts.

The machine is connected to the external air supply via a compressed air regulator. You can use this regulator to monitor and regulate the pressure of the incoming air.

The compressed air regulator is supplied with the machine and needs to be mounted on the side of the machine housing when installing the machine. The regulator has the following connections:

  • 1/8” internal thread, fitted with male compressed air connector to connect the external compressed air supply
  • 6 mm push-in fitting to connect the machine.
NOTICE

Failure of the water separator caused by a wrong alignment of the compressed air regulator.

The compressed air regulator must always be mounted in an upright position because otherwise the water separator will not work.

  • Mount the compressed air regulator in an upright position.

On the left side of the machine are two bores which you can use to mount the compressed air regulator on the machine.

  • Mount the compressed air regulator in an upright position, using the oval-head screws provided in the bores.
