Surface roughness expresses the unevenness of the surface of a solid resulting from the due to the nature of processing and the tool used, the magnitude of which depends on the type of material and the preparation used.

Surface roughness tests – testing capabilities

Surface roughness tests we perform using the Mitutoyo Surftest SJ-301 surface roughness tester with the following parameters:

• feed unit: X axis: measuring range: 12.5 mm;
• measuring speed: 0.25 + 0.5 mm/s;
• detector range: 350 µm;
• measurement method: contact;
• pressing force: 0.75 mN;
• measuring tip: diamond (60⁰/2 µmR);
• parameters: 
  
  • Ra, 
  • Ry, 
  • Rz.
