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 over-sized 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° 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
