Abstract
PURPOSE: To precisely grind valve rod and valve seat sheet sections with a single grinder by using an inner cylindrical spindle which is fixed at the center of the main body as the valve stem section and the guide cylinder of the guide rod.
CONSTITUTION: When the valve rod sheet section is grinded, the valve rod stem section 2A is inserted into the spindle 1B through the sleeve 1E. By contacting the rotating whetstone 1D with a convex cross section with the valve rod sheet section 2, the sheet section is grinded precisely, concentrically with the valve rod stem section 2A. When the valve seat sheet section 4A is grinded, the lower rod 3C of the guide rod 3 is inserted into the valve guide section 4 and the upper rod 3B is inserted into the spindle 1B through the sleeve 1E. By contacting the rotating whetstone 1G with cross section with the valve seat sheet section 4A, the valve seat sheet section is grinded. In this case, the inner cylindrical spindle 1B is fit and slides up and down through the sleeve E centering the fixed guide rod 3. Also, since the outer cylinder 1C for the axis of whetstone rotation and the inner cylindrical spindle 1B are concentric, no deflection occurs.
