Surface Roughness Testers

Surface Roughness Tester is the tester that measures the surface of smoothness and roughness. The instruction for processing surface can be evaluated by using this tester. 

Surface Roughness Tester can express roughness in numbers which cannot be judged by appearance. For manufacturer, surface roughness is one of the most important index for quality control. It can keep the quality longer if it matches exactly to the index.

Our Geared Coreless DC Motor with Tacho Generator is applied for detecting part to move forward and measure the roughness. It requires smooth and very low speed revolution.
