Claims
- 1. A method for grinding and lapping sealing surfaces in slide valves and the like, said method comprising:
- releasably positioning a rotatable tool plate adjacent a said surface to be ground and lapped for rotation about an axis which is generally perpendicular to said surface;
- urging said tool plate against said surface in a direction generally parallel to said axis while rotating said plate to thereby grind said surface;
- measuring the resistance to movement of said plate toward the surface during said grinding;
- checking the planeness of the ground surface; and thereafter
- repositioning the plate and adjusting the force urging the tool plate against said surface as required using the measured resistance as a guide to thereby condition the plate for grinding said surface to the desired planeness.
- 2. A method as set forth in claim 1, wherein said measuring step is performed using a strain gauge.
