Conventional Knee Mills |
Bridgeport Style - Vertical Knee Mills |
| “Willis Machinery” offers five different models of vertical knee mills, both conventional and CNC. Our Bridgeport style milling machines range from the model WM3VS, “Bridgeport” style, 3 horsepower (3HP) variable speed, R-8 spindle milling machine with a 9” x 49” table, to a massive 5 horsepower (5HP), 40 taper spindle, "Bridgeport” Series II style machine with a 12” x 59” table providing 47” of x-axis travel. |

| WM3VS Knee Mill |
1050 Knee Mill |
|
|
|
Dynamically
balanced pulley with special bronze key attached with 2 screws prevents
premature breakage. |
Our
standard spring type micrometer adjusting nut provides quick and
easy movement for setting spindle depth. |
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. |
 |
 |
 |
Our design uses splined shafts which are much stronger and more rigid than the keyed shafts. |
Heavy duty knee with box
ways provide the rigidity
needed for superb support
over the full range of travels. |
1050II and 1250II tables
are capable of supporting
loads from 1,100 – 1,500lbs, respectively. |

| Willis Knee Mills Feature |
-
Willis conventional knee mill models 1050 and 1050II are dovetail and square (box) way machines respectively. These milling machines are 3 horsepower (3HP), R-8 spindle machines, with an optional 30 taper spindle. The vertical mill model 1250II is a 5 horsepower (5HP), 40 taper spindle machine, with square (box) ways.
-
Our milling machine model WM3VS has a rounded ram and column. The knee mill models 1050, 1050II, and 1250II have heavy duty square rams and columns with substantial knees and saddles. These milling machines all maintain “Meehanite” castings with hardened and ground ways as well as “Turcite” coating the adjacent surfaces.
-
Willis conventional milling machine models WM3VS through 1250II are optionally available with electronic variable speed, through a “Yaskawa” inverter, known as the “EV” (electronic variable) models. The electronic variable speed option provides these vertical knee mills with up to 5000RPM in spindle speeds. “EV” spindle speeds are infinitely adjustable through a potentiometer.
-
The vertical knee mill models WM3VS through 1250II are supplied both as conventional milling machines and CNC milling machines.
-
The 1250II head is designed for extra rigidity, with right to left tilt, but without a front to back knuckle.
|
| Optionally available on our Willis knee mills are electrical box packages (option C.) providing a low volt electrical box with transformer, 110 volt outlets, emergency stop button, flood coolant package with switch, and an electronic forward/reverse switch. |
- No more changing of worn out pulley bushings and keys
- Extremely low maintenance
- Accurate RPM readings
- Direct drive belts - no belt slippage
- Reduced energy consumption
