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.
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.
Supplied both as conventional mill machines and CNC mill machines.
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.
