Mechanics use disc masters, or master setting discs, to calibrate measuring instruments and set up standards for gauging. Though people use them for calibrating other gauges, they are never used to make any tools or sensors. They originally designed them in various tolerance grades and for both English as well as metric dimensions. You can find them made of different materials like steel, chrome, or even granite, the most popular being chrome disc masters.
Calibrating gauges is vital in the manufacturing processes where a little deviation from standards could end up in disastrous results in quality control. In the worst case scenario, inaccurate gauges are responsible for producing a machine with non-conforming components. Calibration can also be done in-house, if the gauge users have enough ability to create their own laboratory.
You can use disc masters to calibrate gauges that measure external diameter. They incorporate plastic handles, one on each side. They are essentially bigger plug gauges with a diameter of more than 8 inches. They have a ring like structure and their internal area reduces to decrease weight and for managing the disc master better. Master discs, pins, rings and the other types of setting gauges provide calibration for gauges that you use in the production function, for assessing both go and no-go tolerances. Feeler gauge coils can also be used coupled with chrome disc masters sometimes. Feeler gauge coils are the same as the traditional feeler gauges and you use them to measure the gap's dimension, the only difference being that the traditional ones use blades, while these use coiled tapes for the measurement.
One thing you need to take care of while using master discs is that they should never be rotated while in the gauge. When using with air rings, most people do this, since this is an easy way to find out-of-round situations. But don't do this, because this causes the master to erode and thus cause a disparity in measurements, however small that is. This results in gauge bias. The best way to evade this is by instructing the technicians not to rotate masters while in the gauge.
There are also other types of master gauges like block masters which offer calibration for gauges measuring length or thickness. Disc masters are essentially used to calibrate gauges measuring diameter. If handled well and taken care of, then these master gauges can offer calibration without any discrepancies for a long time. If you are looking for strong master gauges for diameter calibration, then your best choice is chrome disc masters.
When searching for automotive tools and equipment it is best to check online to find the best gauging supplies. Such items like feeler gauges, chrome disc masters, cutting dies, and precision thread plugs are available with several different companies. Just be sure you research the company to make sure you are getting the best custom gauges for your needs.
