The 6 ball Centerline Chuck system was invented and designed by Kwik-Way in the 1920s This design is what set Kwik-Way apart from all other models of valve grinders. It was and still is a game-changer in the world of valve refacing. Unlike any other chuck on the market, the Kwik-Way Centerline chuck ensures precise centering of valves for a flawless re-face. With its unique design, it firmly grips the valve stem at two points, 2.5 inches apart, precisely aligning the valve face with the stem guide. This means that when you’re done re-facing, your valve face will be concentric with the stem guide and perfectly aligned with the valve stem guides themselves.
What sets this chuck apart is its versatility. It’s not just a single chuck, but a compound chuck that combines two chucks into one. It’s a universal chuck, capable of centering any size valve stem used in automobiles. Plus, it’s a compensating chuck that can handle valves with imperfect circumferences or uneven sizes along their length. No other chuck in the world can achieve this level of precision and flexibility.
Operating the air-assisted chuck is a breeze. Two taper collars press down on three sets of balls, gripping the valve stem tightly. The chuck shaft and collars are made from chrome nickel steel, hardened and ground to extreme accuracy with a clearance of just one ten-thousandth of an inch. The balls themselves are also guaranteed to an accuracy of one ten-thousandth of an inch, ensuring an unrivaled level of precision.
In fact, our Kwik-Way Valve Refacer Chuck is so precise that we confidently guarantee it can center a hardened and ground arbor to within two-thousandths of an inch of perfection using our high-performance chuck. No other chuck on the market can offer such accuracy when it comes to valve re-facing.
If you’re tired of settling for subpar results when re-facing valves, it’s time to upgrade to the Kwik-Way SVSIID valve grinder. With the High Performance chuck, you will experience unmatched precision and reliability that can transform your valve re-facing process. Don’t settle for anything less than perfection.
