Overview

This model is equipped with Digital Variable Speed for easy change of spindle speeds.

The model has many unique features compared with most of the similar machines on the market. The quill is CNC ground to a mirror finish and chromed to fit the housing resulting in close to jig bore accuracy for quill downfeed.  Tapered gibs installed on the ways allows easy adjustment for long term usage. The feed handles are designed to spin free which eliminates the friction between the operator’s hand and the feed handle. The bottom of the saddle, instead of the top of the knee ways,  which rides on the knee is hand scraped for better oil retention and prevent dirt and chips from embedded in the knee ways.

  • 9 x 49 ins table, 12 x 36.6 in. travel
  • Digital Vari speed (DVS), speed change by turning a knob, with digital display of spindle speed
  • R-8 spindle, 3 hp , speed (60-4,500 rpm)
  • Spindle runout of no more than 0.0002 ins TIR
  • Hard chromed ways provide long wear resistance
  • Head tilt side to side, up and down
  • One shot lubrication with back flow valve
  • Tapered gibs for adjustment
  • Dual clamps on knee and saddle that locks the knee and table evenly to the column and saddle to avoid skewing. Handles on the clamp are adjustable to 12 different positions.

Improved design of Backlash Eliminator

Backlash Eliminator By Double Nut Design replaces the older design that squeezes a split nut to get rid of backlash. Sharp is the first one to use a double nut design that keeps the feed screw in contact with a pair of bronze nuts. Using a custom tool supplied with the mill, the feed nuts are adjusted to control backlash and held tight with a retaining nut and locking ring.

Patented Knuckle Head design

The New Patented Knuckled-Head Design prevents the head from slipping. The Sharp mills have a knuckle which uses 6 bolts, 3 each side, fitted into circular T-slots with matching nuts securing them from the outside. It locks the head in place for better accuracy and performance than the old design using only 3 bolts to squeeze the casting to hold the head without the T-slots. (Patent No. 5044054)

Better motor shaft support

Roller Bearing Support at the bottom of the motor shaft ensures proper loading, support and alignment of the spindle. It also prevents the distortion of the belts due to tension from long years of milling operation

Crank Handle Improvements

Thrust Bearings mounted at the end of the table and saddle pre-load the feed screw, eliminating end play for precisely controlled lateral movements.
