  • Device of machined parts blow-off. This option includes a special gun with polyvinyl pipe through which air is supplied under pressure from extranet. Air supply is realized onto the block installed on the machine bed and further on onto the gun located on the front surface of the bed in the zone of operator’s location. The operator can make blow-off of removed from the table or electromagnetic chuck machined parts with compressed air by pressing the lever of the gun.

  • Unit for coolant feed and its treatment.

  • Plant for aerosol exhausting from machining zone.
