Abstract International specifications regarding quarts solenoids have recently changed. This study describes the grinding of a precision thread along the quartz bobbin of such a solenoid. Fused quartz being a grinding resistant material, the optimal grinding conditions were clarified. A closed-loop compensation system was applied in which a magnetic scale was used to measure the table feed of ...
