The automatic microhardness tester is mainly used to measure tiny, thin specimens and brittle hardware. It can be widely used in various metals (ferrous metals, non-ferrous metals, castings, alloy materials) by selecting various accessories or upgrading various structures. Etc.), metal structure, metal surface processing layer, electroplating layer, hardened layer (oxidation, various infiltration layers, coating layer), heat treatment specimens, carbonized specimens, quenched specimens, small parts of phase inclusions, glass, agate , Artificial gems, ceramics and other brittle and hard non-metallic materials. It is especially suitable for mass measurement of the hardness gradient distribution curve of the workpiece and the hardness test of the specified part.

The automatic translation stage controlled by the built-in stepping motor can be controlled by clicking the mouse. It has a variety of control modes, high positioning accuracy, good repeatability, fast moving speed, and high work efficiency;
    1 Introduction
Fully automatic micro Vickers hardness tester, integrating optical imaging, mechanical displacement, electronic control, digital imaging, image analysis, computer processing and other professional technologies, realizes the control of the Vickers hardness tester and automatic stage through the host computer , And digitally image the hardness indentation on the computer screen, and then accurately measure the microhardness, hardened layer depth, and thickness of metal and some non-metallic materials, various coatings, and coatings through automatic and manual readings. , Two-point spacing, etc. It can also photograph the topography of the metal surface and perform fixed-magnification printing. This system breaks through the traditional hardness test method and realizes a fully automatic, high-precision, and highly repeatable hardness test. It is an important equipment for material analysis.
   2. Composition
The computer host controls the action of the hardness tester and receives the corresponding information of the hardness tester through the RS232 serial port; the computer host controls the platform control box through the RS232 serial port, and controls the movement of the automatic stage and receives the corresponding information through the platform control box; Vickers hardness The optical signal of the indentation pressed by the meter is imaged on the computer monitor through a digital camera, and then the Vickers hardness value is measured through automatic and manual reading.
