KWIK-WAY SVSII Valve Refacer

Consistent Accuracy:

The main advantage that others have failed to duplicate is Kwik-Way’s exclusive six-ball centerlining chuck. The two sets of balls (three in each set), automatically find the existing valve stem centerline. 

This chuck handles any valve stem from 4mm to 14.3mm.  
Other machines can require as many as nine separate collets to achieve the same range. Collet and "so-called centerless grinders"  transfer wear from the valve stem directly to the valve face during grinding. Historically, these designs are only capable of achieving their advertised accuracy on NEW valves.
The Kwik-Way Six-Ball, Centerlining Chuck design triangulates (or centers in) the wear area of the valve stem in order to grind the face concentric to the actual stem centerline.  Because the two sets of centering balls act independently, 
taper on the valve stem will not affect accuracy (even on new valves).  
This feature is available EXCLUSIVELY with the SIX-BALL CENTERLINING CHUCK - a standard feature on all KWIK-WAY SVS II DELUXE Valve Refacers.
The Kwik-Way design features dovetail ways which remain adjustable for long-term accuracy. The valve position swivel plate is indexed in 1º increments to ensure accuracy of grinding angles from 13º to 62º.
