4. Performance description andTechnical Specifications

4.1 Performance Description

* GermanyKBcompanyThe new generation hardness testing machine produced is convincing with its precision and reproducibility. The KB250MHSR-FA hardness tester can be used to test the hardness of materials and can achieve automatic measurement. It is used for hardness testing with a test load of 0.2-250kgf, and complies with various international standards (such as DIN EN, ISO, and ASTM standards). The standard hardness measurements are Vickers, Brinell, Rockwell, and Knoop measurements; KB Company has obtained the qualification of DKD calibration laboratory supervised by the German National Calibration Agency, and issues DKD certificates to precision testing instruments and accessories that meet international standards after calibration and calibration. In addition, KB company has a German national laboratory certified by ISO/IEC 17025 standard, and has the technical capability to carry out calibration/testing in accordance with relevant international standards.

* Fully automatic electronic control closed-loop sensor loading system:Wide testing force range, high precision, suitable for calibration, flexible control, and no overload; Automatic loading, unloading, and intermediate load changes;

* LED照明光源：LED cold light source lighting is low-cost and has a long lifespan (over 10 years), achieving automatic control of lighting brightness;

* 6Automatic transfer of workstation to towerThe objective lens and indenter positions of the 6-station can be freely equipped, suitable for switching between various hardness measurement scales to avoid the need for adjustment programs caused by indenter swapping, and improve work efficiency;

* USBHD camera:A high-resolution 5-megapixel camera equipped with a USB interface can capture high-quality images, greatly improving the accuracy of automatic measurement, and has a 3.5-fold digital zoom to increase the measurement range of the same magnification objective lens;

* X-YAutomatic loading platform(Standard itinerary)180×160mm）：By using a stepper motor for direct transmission, various positioning errors caused by intermediate links can be eliminated, resulting in high positioning accuracy (the repeatability of this matching automatic table is less than 4 microns), simple structure, smooth movement, low noise, low friction and wear of moving parts, and long service life;

* probeZDual guide rail control for axis movement:The upward and downward movement of the probe in the Z-axis direction adopts a dual guide rail design. The rapid and large-scale movement of the probe in the Z-axis direction and the focusing of the probe on the sample surface are completed on their respective guide rails. The Z-axis movement of the probe is controlled by software to ensure both rapid and efficient movement of the probe and accurate positioning accuracy during sample surface focusing (positioning accuracy of 5 microns);

* Mathematical and statistical functions:Test data editing, minimum value, maximum value, average value, chart display, standard deviation cp、cpk、 Histogram;

* automaticMeasurement process:The surface indentation of the sample is quickly focused by a CCD camera embedded in an optical objective lens, and a clear indentation image is obtained on the LCD interface. The indentation measurement is carried out by manually adjusting the measurement line in the software interface to ensure the accuracy and reliability of the test data.

* Auto focus:Very fast automatic focusing, easy to manually capture images for image improvement;

* automaticlight sourcebrightnessadjustcontrol：Automatically adjust LED lighting before measuring each indentationSouth HoodLight control effect, meeting automatic measurement and automatic focusing of different surfaces, improving measurement repeatability;

* Software interface operation functions:The following functions can be set and operated on the software interface, and logical operations are more convenient to use (the VNet 0SR-FA fully automatic hardness measurement system does not require a digital panel to complete the test in the automatic measurement software interface). The video images captured by the built-in camera are converted into digital images and displayed on the LCD screen

Multiple languages to choose from, including German, English, French, Italian, etc;

* Measurement interface operation:It adopts a very convenient human-machine dialogue method, and the indentation image on the LCD screen is very clear. The sharpness and contrast of the indentation image are high, and the magnification distortion is very small;

* Hierarchical user management:Can control the authorization level of operators.

* Optical zoom function(Optional): Comes with an optical multiplier (10 levels, 1:7 magnification). This optical zoom is achieved through optical magnification rather than digital magnification, making it possible to obtain high-quality images through large-scale magnification. The application of KB's optical zoom mechanism enables the hardness machine to only require one objective lens instead of multiple objectives, which inevitably reduces the cost for users. KB's optical zoom allows testing to meet a wide range of test load standards, abandoning the method of changing the magnification by changing the objective lens. By using optical zoom images, they can also be recognized under the premise of meeting the standards;

* Panoramic scanning modeOptional：By using a low magnification objective lens, the shape of the sample can be scanned and memorized at high speed to create an image as a reference for the position of the test program or to indicate the hardness measurement position. The area or contour can be scanned; Satisfy the scanning and testing of samples with non parallel surfaces, and equip the scanning process with automatic focusing, light control system, and X-Y automatic stage to quickly complete the scanning of the sample surface;

* Vickers testing program for welded parts(Optional): It can meet the requirements of all welding component testing standards. The tested parameters and individual indentation can be marked on the scanned welding specimen image;
