What is the quantity of precision machinery factory? How to use it?

There are many measuring tools in precision machinery factory. If it is a big factory, there must be a testing laboratory, including physics and chemistry, mechanics, geometry and so on.

Physical and chemical experiments need spectrometer to analyze elements;

Mechanical experiments need tensile testing machine, impact testing machine, hardness tester, etc.

If you do experiments with geometric quantities, you need more. Profiler, roughness meter, length measuring instrument, laser interferometer, white light interferometer, etc.

The profilometer and roughness measure the contour size and roughness of the product through contact scanning, and the accuracy is in the micron level.

SJ57 18 profiler

The length measuring machine is mainly used for internal calibration of various measuring tools, such as gauges, measuring blocks, calipers, feelers, inspection rods, indicating meters, etc.

SJ5 100 Length Measuring Instrument

Laser interferometer is mainly used to calibrate the accuracy of various machining machines.

SJ6000 laser interferometer

The surface micro-morphology after ultra-precision machining is measured by white light interferometer, and the accuracy is between sub-nanometer and nanometer.
