Type of surface roughness comparison model the machined surface (outside the car park outside the park, planing, grinding, milling, boring hole, flat milling, end milling, grinding), wire cutting, EDM, polishing, casting sand, steel shot blasting, sandblasting surface and polishing surface etc.. It is through the visual and tactile, use the comparative method to check the workpiece to calibrate the surface roughness, and provide guidance for the design of specific processing methods and the degree of roughness and the intuitive feeling and appearance characteristics can also be used as visual aids in mechanical professional colleges. Its characteristic parameter is the arithmetic mean deviation Ra of the surface profile. It fully conforms to the national standards GB-6060-2, 3, 4, 5 and the
national verification regulations JJG102 technical requirements.
Main features:
The surface roughness comparison template, the material is nickel alloy, adopts the precision electroforming replication process, advanced technology, stable quality, the most complete specifications. The product has the advantages of high hardness, good wear resistance, and no rust, and is especially suitable for the production site.
