ZYS had been successfully developed Series CU Laser roughness measuring instrument in the eighties, after ten years development, it forms serialization and is widely used in the bearings industry. Features • Non-contact measurement, it can not scratch the surface and can eliminate measuring error which comes from that the measuring tip can not be brought into the bottom during high-level roughness measurement, it Particularly suitable for workpiece surface roughness measuring after superfinish process. • Because of the laser coherence, it enable the measuring system structure simple and eliminates inconvenience of the general interference light measuring instruments because of its small vision. • Reasonable structure and perfect mathematical model, which greatly reduces possible error the light source due to changes in surface reflection coefficient and the external interference of different, showing the value of stable and reliable measurement of high precision.
