・New 5-Face Machining Software(M-VB25-5F)

5-face machining software automatically performs the spindle end coordinate shift, name change of shifted coordinate axes, and other troublesome work necessitated by replacement and indexing of the dummy plate or attachment. The program can easily prepare side face machining code, using the same methods as ordinary programs ? that is, by taking each face as a plane defined by X and Y coordinates. Not only on 90 degree sides but also on inclined faces in 1 degree increments. This software includes custom macro functions and 3-dimensional coordinate rotation function, so no additional special equipment is required.

  • For machining of all faces, the program treats the tool axis direction as the Z axis, the horizontal as the X axis, and the vertical as the Y axis.
  • Tool length must be taken into account when preparing programs.  (Tool compensation function can be used.)

Easy Maintenance

  • All maintenance related equipment is concentrated in one location for operators or maintenance personnel to access easily.

  • Coolant enclosure without top (US standard)
