The Lapmaster Wolters LBVS has been developed to produce very accurate spherical surfaces on a variety of Ball Valves. A scratch free, matt high-quality surfaces is obtained on the Ball Valve and Seat. The machine match laps two Seats to the valve, achieving a perfect mechanical seal for any pressure requirement.
Dec 11, 2015· Next, the internal diameter was precision honed and measured for pinpoint locating. Finally, a CNC spherical grinding operation was performed to create a perfectly spherical outside diameter with a tight sphericity tolerance of 0.0001” and an 8Ra micro finish. Fulfilling the Most Extreme Grinding Tolerances
