Parallels, Surface Finish & Hardness Testers

Shore Hardness Tester, Analogue HB Series hardness tester with slave pointer for measuring penetration depth Shore A: rubber, elastomer, neoprene rubber, silicon rubber, vinyl, soft plastics, felt, natural leather and similar materials Shore C/0: foam, sponge Shore D: plastics, synthetic resin, resopal, epoxide, perspex etc. Max. mode for recording peak values Point mode shows stable measurement value Dimensions: L x W x H: 115 x 60 x 25 mm Weight: 160 g Tester Shore A Parallels, Surface Finish & Hardness Surface Finish Any machined component has a surface geometry which consists of three basic elements: Form or Curvature - Whether the surface has irregular bumps or dimensional changes Waviness - Whether the surface has regular repetitive ripples or patterns (e.g. milling patterns) Roughness - The shapes or irregularities that are smaller than, and form part of the waviness pattern (e.g. material micro-structure) Waviness and roughness are traditionally the most difficult elements to measure when comparing surface finish, however, they have a radical effect on the performance of the finished component. Variations will cause aesthetic appearance changes, component wear variations, oil retention variation etc. Many manufacturers therefore specify a range of roughness values which their components should be manufactured to, often expressed as: Ra, Rq (RMS), RzDIN, Ry, Sm,mm.
