WF 650 FK

Highlights

The WF 650 FK is a state-of-the art high-performance universal milling machine for precision single and variable batch production with a perfectly accessible working area.

The WF 650 stands out with a spacious working area while having compact overall dimensions and a maximum height of no more than 2.30 m
– an ideal solution for low workspaces.

The FK version of the WF 650 is equipped with a manually pivotable milling head and quill.

The special KUNZMANN features:

  • elaborate cast iron column design with high stability and inherent rigidity
  • vertical milling head, pivotable -5/+95°, with extending quill
  • vertical milling head with integrated Z axis collision absorber
  • high-torque main drive
  • standard 38-pocket tool changer
  • clearance-free profile roller guideways
  • distance-coded linear encoders
  • circulation lubrication for milling head
  • ergonomically convenient machine with spacious front and side door
    and thus perfect workroom accessibility

Slat band chip conveyor

  • for long chips, steel chips or wool chips
  • chips are separated by material
  • for high-chip volume manufacturing

Conveyor height: approx. 1,250 mm
Conveyor width: approx. 350 mm

Digital B axis display

The swiveling angle of the milling head is digitally indicated on the control display.

Probe systems

In combination with the control probing cycles, switching 3D probe systems simplify set-up, measurement and control functions during processing.

Tool measurement

The following tool data is precisely determined via the control cycles:

  • tool length
  • tool radius
  • tool wear

CNC dividing head

By including a CNC dividing unit, you can process your workpieces from various sides.
Programming is done via the 4th axis of the control.
The dividing unit can be fastened vertically or horizontally on the angular table.

Center height: 160 mm

Heidenhain TNC 620 contouring control

The Heidenhain TNC 620 is a compact and versatile contouring control with 3 closed-loop axes and the option to add a 4th axis (B axis, e.g.) by CNC dividing head.

Workshop-oriented programming with Heidenhain conversational programming language or DIN-ISO-Code
