| Description | Tester TypeSurface Comparator Product Details 30 Piece Specimen Comparator This has reference plates manufactured from electro-formed solid nickel, which give improved wear characteristics and definition of surface finish. It is invaluable for tactile and visual inspection of machined component finish. Metric Ra and imperial AA samples are included. Supplied in a PVC wallet (165 x 85 x 10 closed). Production is as standardised in ANSI B46.1 - 1978 military standard 45662. RS, Professionally Approved Products, gives you professional quality parts across all product categories. Our range has been testified by engineers as giving comparable quality to that of the leading brands without paying a premium price. Key Characteristics Machining method finish Flat lapping 2, 4, 8μ, AA Reaming 16, 32, 63μ, AA Grinding 2, 4, 8, 16, 32, 63μ, AA Horitzontal milling 16, 32, 63, 125, 250, 500μ, AA Vertical milling 16, 32, 63, 125, 250, 500μ, AA Turning 16, 32, 63, 125, 250, 500μ, AA 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 changesWaviness - 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. |
