Description

Technical Field

[0001] The utility model relates to the field of measurement and detection, in particular to the detection of diamond rollers and electroplated CBN grinding wheel tools. Background Art

[0002] Diamond dressing roller is a grinding wheel dressing tool for special machine tools and gear grinders used for mass-produced profile grinding. It uses a rotating tool with many small diamond particles embedded on the working surface to dress the grinding wheel. Since the tool itself is a rotating body and is independently driven to rotate at high speed during operation, it can not only dress the grinding wheel surface with high precision, but also has obvious advantages over other tools in terms of dressing efficiency, tool life and operation mode.

[0003] Electroplated CBN grinding wheel is a grinding wheel that is electroplated to fix the abrasive grains on the working surface of the grinding wheel matrix. Electroplated CBN grinding wheel has great advantages in grinding, mainly reflected in simple manufacturing process, high grinding accuracy, long life, easy application, and the matrix can be reused, saving costs, and can give full play to the characteristics of abrasive grains in high-speed and efficient grinding.

[0004] In the common sense, the surface accuracy and form tolerance inspection of diamond rollers and electroplated CBN grinding wheels is carried out through the deflection instrument. However, the deflection instrument cannot effectively meet the inspection requirements of diamond rollers, and the deflection instrument is often large in size and inconvenient to move after being placed. The product can only be fixed in a certain position for inspection, which affects the inspection efficiency to a certain extent. Therefore, it is very important to design a new and convenient instrument that can effectively meet the inspection requirements of diamond rollers and electroplated CBN grinding wheels.
