Gauge maintenance and care

The gauge is a length measuring tool that judges whether the measured length is acceptable or not based on the fit gap with the device to be tested, the degree of light transmission, or whether it can pass the device to be tested. It is understood that the commonly used gauges are gauge blocks, angular gauge blocks, multi-faceted prisms, sine gauges, rulers, flat feet, flat plates, feeler gauges, flat crystals and limit gauges.

(1) Do not touch the working surface of the gauge by hand to avoid rust.

(2) Whether it is a gauge that is frequently used or a gauge that is not frequently used, it is necessary to perform an external inspection periodically to see if there is any damage, rust or deformation. If it is found that the gauge starts to rust, it should be put into the gasoline for a period of time, then carefully removed and cleaned with anti-rust oil.

(3) During use, the gauge should be placed in an appropriate place, such as the table top of the tool cabinet or the wooden pad on the fixed part of the machine tool, not on the machine tool holder or on the machine guide rail to avoid damage.

(4) Do not keep the working surfaces of the two gauges together (such as the plug gauge and the ring gauge), otherwise the two working surfaces will be glued to each other, and the external force will be unnecessarily damaged when separated.

(5) After the gauge is used, it should be cleaned with clean cotton or soft cloth, placed in a special wooden box, and then stored in the tool cabinet; the sheet gauge can also be hung in the tool cabinet. If the weather is wet or can be used after a while, wipe it clean and apply a layer of acid-free Vaseline or anti-rust oil. The place where the gauges are kept must be dry.

(6) The gauge should be inspected regularly. The general inspection period is 6-12 months.
