Horizontal milling and boring machine HCW 1 – HCW 4

HCW 1, HCW 2, HCW 3, HCW 4 – fully hydrostatic horizontal boring machine, which allows to achieve excellent results during the machining process when removing huge chips, as well as during very precise finishing of the workpiece.

Operation of the machine

  • Main operator’s panel is placed outside the working area on the operator’s platform, where the operator is protected against influences of the machining process (flying chips, broken parts of tools and workpiece, cooling liquid, etc.) by means of cabin with moveable front part.
  • With one lockable switch the operator can select following modes of machine’s operation
