How Do You Maintain A Precision Measuring Tool?
• Be sure that the work pieces have stopped. Measuring work pieces on lathes should be carried out only after the work pieces have stopped; otherwise, the accuracy of the tool may be negatively impaired due to wear of the measuring faces and accidents may occur. • Wipe the measuring faces of a precision measuring tool and the to-be-measured surface of the work piece so as to prevent the measuring accuracy from being negatively affected by dirt or dust. It is not advisable to use such precision measuring tools as vernier caliper, micrometer and dial indicators to measure those forged roughcasts or abrasive-bearing pieces (like carborundum), because the measuring faces will be abraded and accuracy will fall. • Never put precision measuring tools together with hand tools, such as cutting tools, files, hammers and drills for the fear of bumping the precision measuring tools. Never put them on lathes either to prevent them from dropping from lathes and breaking down due to vibration of lath
