Resurfacing

If it is a small product such as a precision measuring tool, it is better to say, because the measuring tool is small in size and easy to calibrate and repair, it can be sent to the relevant laboratory for repair; and the cost of repurchasing is not high.

However, the super-large equipment (composed of precision granite components, ceramic components or precision metal components) used by some companies is not convenient to send to relevant laboratories for calibration and repair, which requires qualified suppliers to come to repair . Because the precision equipment required is more expensive, such as laser interferometers, electronic level gauges, dial indicators and other related instruments. At present, the quality and functions of Renishaw's laser interferometers in the world are at the top level in the world. The level gauges produced by Swiss wyler are widely used and reliable in quality. Instruments such as dial gauges produced by mahr and mitutoyo are also at the world's leading level. If you can not measure it, you can not make it.

According to local inspection standards, such as DIN 876 Standard, Federal Specifications GGG-P-463c, etc., each panel must pass repeatability and overall flatness tests to obtain legal certification. The allowable tolerance of the panel is defined by its size and grade.
