laser roughness measuring instrument PerformanceZYS had been successfully developed Series CU Laser roughness measuring instrument in the eighties,Website:://.zys-bearing.com, 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.• Advanced circuit design, automated data collection, automatic analysis and calculation, digital direct display Ra, Ry and ball grade value, measuring efficiency, human error.• Adjust apparatus is simple, easy to operate, less demanding work environment, in particular, apply to the workshop, processes or checkpoints, are enterprise processes an important means of quality control. CU0008, CU0013 raceway roughness laser measuring instrument used to measure the outer/inner ring raceway surface roughness for single row radial ball bearing.
