7. Optimize each step, greatly improve overall performance compared to traditional hardness testers, and save time50%

The advantages of visual system over eyepiece measurement

1. Measure directly on the surface that needs to be measured without visual error. Traditional hardness testers use eyepieces for measurement, and the scale line and indentation are not on the same plane. Under different viewing angles, there will be visual differences between the scale position and indentation position, resulting in differences in measurement results from different viewing angles and personnel

2. High measurement accuracy: There is no problem of mechanical eyepiece backlash. The resolution of the mechanical eyepiece spiral micrometer scale isAbout 10 μ m, and there is mechanical hysteresis, so the measurement method needs to be strictly defined. The pixel spacing of the image sensor in the visual system is 7.5 μ m, with relatively high accuracy and good measurement consistency

3. Multiple measurement methods can be provided for simultaneous two-dimensional measurement, simplifying the measurement process and improving measurement speed

4. Equipped with rectangular tangent measurement method

5. No visual fatigue, reducing measurement labor intensity. The Aolong visual system adopts65K true color TFT LCD screen, comfortable to observe without fatigue, and can be measured by multiple people at the same time

Technical Parameter

sample requirements

Although Vickers hardness can measure both softer and harder materials, it also has its own requirements for the sample. Only by selecting appropriate samples can we avoid the errors caused by this and obtain accurate Vickers hardness values.

Appearance requirements for the sample

The surface of the Vickers hardness test sample should be smooth and flat, without oxide scale or impurities, and without oil stains. Generally, the surface roughness parameter of Vickers hardness test specimensRa is not greater than 0.40 μ m, small load Vickers hardness specimens are not greater than 0.20 μ m, and micro Vickers hardness specimens are not greater than 0.10 μ m. (μ m is the unit of surface roughness parameter Ra.). ）

Requirements for sample preparation

During the preparation process of Vickers hardness specimens, the influence of factors such as overheating or cold work hardening on surface hardness should be minimized as much as possible.

In addition, for samples with small cross-sections or irregular shapes, such as spherical or conical shapes, it is necessary to embed the samples or use specialized platforms.
