  Visual Vickers Hardness Tester MHVS-5V MHVS-10V MHVS-30V MHVS-50V
THE PREVIOUS

  • Product introduction
    Unlike the traditional Vickers hardness tester, this vision series Vickers hardness tester cancels the use of measuring eyepiece, projectes the Vickers indentation image to the operating screen, and can measure the indentation diagonal in the screen. The test process is faster and more intelligent to meet your requirement for efficient, convenient and accurate hardness testing.
     
    Characteristics of Control System
     
    High Precision Step Control Electric Loading Technology
     
    u Loading speed of main test force is very fast and efficiency is improved.
    u Real-time video measurement, better effect, more accurate and more stable
    u High Precision Sensor Cooperating with "Olongson" Control System
    u "Aolongxin" Unique Value Curve
    u Loading and unloading speed is faster and more accurate
    u Using Unique Embedded Vision Technology
    u Measuring operation is simple and human error is greatly reduced.
     
    u It can realize remote control and is easy to operate.
    u Extremely Fast Loading Speed: Loading Time of Test Force 2-10 seconds
    u Intelligent control of the whole process. Sectional force application, smooth speed change, high precision and high speed step control, etc.

    Visual system charactiristics
    u Objectivity: The visual system has objectivity, and the results of analysis are not affected by subjectivity.
    u High gray resolution: human eyes generally have 64 gray scales, and machine vision can reach 256 gray scales.
    u Embedded image technology replaces traditional measuring eyepiece, using camera + display mode, indentation image, direct display screen.
    u Type of Visual Chip: Industrial-grade Special High Definition Camera
    u Contrast, brightness, white balance and other adjustments are available.
    u Visual analysis model simplifies manual operation process, reduces operator fatigue, and makes measurement data more intuitive and convenient.
    u Optimizing each link greatly improves the overall performance of the hardness tester and saves 50% of the time compared with the traditional hardness tester.
     
     
    Advantages of vision system relative to eyepiece measurement
    u There is no visual error when measuring directly on the surface that needs to be measured. The traditional structure of hardness tester is measured by eyepiece. The calibration line and indentation are not on one plane. Under different angles of view, the calibration position and indentation position will produce visual difference, which leads to different angles of view and different results of personnel measurement.
    u High measurement accuracy: there is no problem of mechanical eyepiece error. The calibration resolution of mechanical eyepiece helical microstructures is about 10 m, and there is mechanical backlash, so it is necessary to define the measurement method strictly. Pixel spacing of image sensor in vision system is 7.5 m, which has high precision and good measurement consistency.
    u It can provide two-dimensional simultaneous measurements of various measurement modes, simplify the measurement process and improve the measurement speed.
    u With rectangular tangent measurement method
    u No visual fatigue, reduce the measurement of labor intensity. Aolong vision system uses 65K true color TFT LCD screen, which is comfortable to observe, not fatigued, and can be measured by many people at the same time.

    Sample requirements
    Although Vickers hardness can be used to measure both soft and hard materials, it also has its own requirements for specimens. Only by choosing the appropriate sample can the error be avoided and the accurate Vickers hardness value be obtained.
    Sample appearance requirements
    The surface of Vickers hardness specimen should be smooth and smooth, no oxide skin and impurities, no oil stain. Generally speaking, the surface roughness parameter Ra of Vickers hardness specimen is not more than 0.40 micron, that of small load Vickers hardness specimen is not more than 0.20 micron, and that of micro Vickers hardness specimen is not more than 0.10 micron. (Micron is the unit of surface roughness parameter Ra.)
    Requirements for sample preparation
    During the preparation of Vickers hardness specimens, the influence of overheating or cold hardening on surface hardness should be minimized.
    In addition, for small cross-section or irregular shape specimens, such as spherical or conical, it is necessary to mosaic the specimens or use special platforms.
