1250II Knee Mill

Description

Willis Knee Mills Features:
- Our 5000VS model has 5HP variable speed 60-3600 RMP, 40 taper spindle. It has a hardened ground table surface with built in tool trays on either side, with a chrome plated precision ground quill, full 4-1/8" diameter.
- Willis conventional knee mill models 1050 and 1050II are dovetail and square (box) way machines respectively. These mill 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 mill 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 mill machines all maintain “Meehanite” castings with hardened and ground ways as well as “Turcite” coating the adjacent surfaces.
- Willis conventional mill 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 mill machines and CNC mill machines.
- The 1250II head is designed for extra rigidity, with right to left tilt, but without a front to back knuckle.
