Automatic Precision Micro Hardness Tester JMHVS-1-XYZ

Description

Mitech JMHVS-1-XYZ automatic precision micro hardness tester,based on the mechanical principle of the positive quadrilateral pyramid diamond indenter into the sample surface to produce indentation.By measuring the diagonal length of the indentation to achieve the hardness of the material.It is designed for small specimens,thick workpiece, heat treatment of the workpiece surface (infiltration coating) Vickers hardness test.With high automation degree,accurate measurement, integrated electromechanical integration in one,and the use of photoelectric sensor system to high magnification optical measurement,it is equipped with automatic turret device,high sensitivity touch screen operation interface to achieve automatic loading and unloading,automatic indentation marks,micro-auto focus measurement indentation diameter,GB/ASTM hardness automatic conversion, automatic test report and other functions.With the function of easy to operate and high efficiency,it is widely used in metal processing,electronics industry,mold parts,watches and clocks manufacturing,engineering quality inspection,and other fields,scientific research institutions etc.and it is the ideal hardness test equipment for sophisticated manufacturing and quality inspection departments to test materials.

Working Principle
The testing principle of Micro Vickers (or Knoop) hardness is the using of regular four-pyramid diamond pressure head, the selected fixed experimental force (load) is pressed into the specimen surface and maintained for a certain length of time (Paula), and then the experimental force (unloading) is removed.A positive pyramid or Knup indentation with a square on the surface of the specimen remains.The length of the diagonal is measured by the micrometer (0.020~1.400mm) to obtain the area of the indentation and to obtain the corresponding Vickers (or Knoop) hardness value.

Usually Vickers hardness values can be converted according to the following formula:
HV = constant × test force / indentation surface area ≈0.1891 F / d2;
Note: HV: Vickers hardness symbol; F: test force (N); d: the arithmetic mean of indentation two diagonal d1, d2

Working Conditions

• Operating temperature: 18℃~28℃;
  
• Relative Humidity: ≤65%;
