Sauter Hårdhedstester HN-D Leeb

HN-D målepen Leeb hårdhedstester fra Sauter. Giver avancerede funktioner, velegnede til en bred vifte af anvendelser.
Hårdhedstesteren fungerer ved at fremskynde et indvendigt prelmodul mod den testede genstand. Afhængigt af genstandens hårdhed opsuges belastningens kinetiske energi. Hastighedsnedsættelsen måles og omdannes til hårdhedsværdier.

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.
