CU9505B

　　 Our corporation had been successfully developed Series CU roughness Laser measuring instrument in the eighties, after ten years development, it form serialization and be widely used in the bearings industry. It had got national science and technology prize third grade and ministry of machine-building industry science and technology advancement prize, second grade. the product had achieved national patent is the company successfully developed the eighties, and perfect, and is a new type of roughness measuring instrument, one of the recipients of third-country Machine-Building Industry Award and second prize of scientific and technological progress.
　　 This series used most innovative measuring principle of laser reflex facula theory that reflex facula core / band energy ratio is the function of the workpiece surface roughness , the correlation curve is obtained by theoretical calculate and analyse with a large number of experiments, contrast with other measuring methods, it has more obvious advantages.

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.
