1250II CNC Vertical Knee Mill

Maintaining all of the standard features accompanied with the Willis conventional knee mills, Willis CNC knee mills also posses ACU-RITE CNC controls with 2 (two) or 3 (three) axis capabilities.

Willis Machinery offers either the "ACU-RITE" MillPWR G2 CNC control on four of its conventional mill machines including the WM3VS, 1050, 1050II, and the 1250II.

  • Willis CNC knee mills all possess precision ball-screws and nuts on all CNC axes

  • These CNC vertical mill machines are offered with 2, 3, 3½, or 4-axis controls

  • A disengageable quill is available on 3 (three) axis CNC knee mill models for manual drilling and tapping

  • Willis, 2 (two) axis, CNC knee mills are equipped standard with a third axis quill scale digital readout display

  • Willis CNC Knee Mills offer semi-automatic operations of full 2 (two) or 3 (three) axis CNC operations.

  • Powerful A/C brushless servo motors provide these CNC mill machines with smooth and accurate positioning

  • An automatic, metered, lubrication system with low level alarm is standard on Willis CNC knee mills

  • Optional Servo or Align power knee feed is also available on Willis CNC mill machines


Special Features


One piece construction is superior to our competitor's 2 piece.


Our design uses a splined pinion shaft which is much stronger and more rigid than the keyed shaft.


Our standard spring type micrometer adjusting nut provides quick and easy movement for setting spindle depth.


Gaskets are used to prevent grease and oil leakage.


One pieces quill housing ensures precise alignment, eliminates vibration, and prevents premature bearing failure.


Dynamically balanced pulley with special bronze key attached with 2 screws prevents premature breakage.


Our special power down feed parts are so strong, they can be used over 3,000 RPM spindle speeds. Our 1 piece cluster gear is superior to the much used 3 piece design.


The splined shaft is much stronger and provides greater safety than the keyed shaft.
