Salient Features

Use of seasoned and stress-relieved castings. The rigid base provides vibration-dampening properties. The auto lubrication system maintains the floating action of the saddle. The hydraulic-driven saddle enables vibration-free travel.

The bearing shells of the grinding spindle are multi-surface, adjustable by means of tapered sleeves.

Wheel Head needs no maintenance apart from occasional oil changes resulting in high-pressure stability, chatter-free grinding, avoidance of swimming tendencies of the pure hydrostatic system, and wear & vibration-free running. Less adjustment time due to the rotating cam feature of the Cambering System. The Wheel Head Saddle base is hinged to enable the precise forward and backward movement of the wheel for concave and convex grinding.
