NEW 12" x 58" SHARP MODEL V-1 VERTICAL KNEE MILL

These vertical knee mills are equipped with vari-speed drive, available with optional digital vari-speed. The dove tail ways chromed, and the box ways are hardened and ground.

Head
The 5 HP motor is equipped with Digital Variable Speed drive that allows the change of spindle speed by simply turning a knob.
The motor shaft and Vari Drive pulleys are dynamically balanced, then hard-chromed this allow a vibration free milling even at high speed.
An oversized 4-1/8” diameter quill is used for heavy duty milling along with the #40 taper spindle.
A matched pair of super-precision ABEC-7 angular contact bearings supports the spindle. The quill is CNC-ground to a mirror finish, and then chromed to fit the housing. Together, they insure spindle run out of no more than 0.00002” TIR
Beside swiveling 90 degree side to side, the head can also swivel up and down by virtue of a knuckle joint design. The new design developed by Sharp uses 6 bolts, 3 each side, that fitted into a circular T-slot milled at the inside of the over arm and secured by nuts from the outside. It secured the head tightly and offered high accuracy in milling operations.
Column, Table and Knee
Hardened and ground box ways on column and saddle are used for extra rigidity.
Power Feed Table and Saddle are installed standard
Certified MEEHANITE castings with high tensile strength are fully ribbed for better dampening of vibrations.
Manual movement of the table is controlled by a hand wheel installed at the front of the table for easy operation.
Table and saddle backlash is controlled by a double-nut design that keeps the feed screw in contact with a pair of bronze nut at all times. A unique SHARP feature. "Bridgeport-style" vertical knee mill
The saddle is built with extra width to fully support the entire travel of the table.
Knee elevation is powered by a single 1-1/2 HP motor for rapid positioning of heavy work piece.
Table and saddle movement is powered by individual control with rapid traverse function.
