System description

Can carry out panoramic scan, edge scan.Automatic completion of continuous pressure, load protection, reading, data recording, by choosing a measurement method all measurement will be automatically and quickly completed;

Choose straight lines, zigzags, circles, arcs, random points, matrices and self-learning modes according to different needs;Improve the readability of non-clear indentation on non-smooth surface by data processing software;

The depth of hardened layer formed after continuous measurement can be displayed in table form.

It can output all kinds of data measurement data, hardness value table, hardening layer depth, maximum value, average value, minimum value.

Hardness tester control

The hardness tester can be controlled automatically: automatic turret (objective lens, pressure head, objective lens automatic switch), automatic loading, automatic measurement control

The brightness of the light source of the microhardness tester can be set

Select the conversion of the control objective lens and reflect it in the software interface to change the calculation parameters

Select or start control durometer indenter automatically to load position, load, hold, unload, and automatically turn back to measuring objective position

The load set by the hardness tester can be automatically reflected on the software interface

Z axis control

Z axis automatic movement, automatic focus

Control platform movement mode (Patten)

The software system can control the automatic loading platform for programming and moving, and can carry out:

1) Measurement mode (Random A)

Use this mode to press and read an optional point.

2) Measurement mode (Random B)

Measure and read arbitrary points.Rotates the selected coordinate position at any Angle.

3) Horizontal (X-axis direction) pressure and read

4) Longitudinal (Y-axis direction) pressure and reading

5) Measurement mode (Line Set A)

Use this mode to press and read in the direction of the surface at an Angle (zigzag movement, i.e. the broken line movement of the hardened layer depth measurement).

6) Measurement mode (Line Set B)

Use this mode to press and read at regular intervals.

7) Trajectory coordinate movement and other mobile programming methods

Above 8 lines can be set at the same time, each line can be set 999 positions

Measuring way

Automatic mode: automatic loading + automatic measurement + automatic display of measurement results

Can measure the player's movement pattern

Image acquisition/recognition methods

High quality, high resolution camera, resolution of 5 million, large size original image acquisition;A variety of image compression methods for easy use (the image and measurement results for storage format, image storage format BMP, JPG and other general file formats).

Automatic vickers indentation measurement system using pixel identification technology, through a dedicated vickers hardness indentation analysis software to analyze indentation image, the analysis software using digital image processing technology edge segmentation algorithm to test indentation edge extraction, and then by using the theory of wavelet multi-resolution analysis test indentation sampling signal, using the least squares fitting creasing edge line, In order to extract the indentation edge of micro-hardness, the indentation area of micro-organization vickers hardness test can be extracted quickly and accurately, and the value of Vickers hardness can be calculated automatically, and the readability of non-clear indentation on non-smooth surface can be improved.

Automatic measuring time

About 0.3 SEC /1 indentation

Repeatability of measurement

±1.0%  （700HV/500gf）

Minimum detectable indentation

About 5mm (automatic measurement)

Minimum unit of measurement

0.01mm

Data output format /

Editing features

Inspection report can be customized according to user requirements;

Through data processing software, the depth of hardened layer formed after continuous measurement can be displayed in table form.

It can easily output all kinds of measurement data, hardness value table, hardening layer depth, maximum value, average value, minimum value, display and output color image with hardness value;

Data such as hardness value, hardness table, hardening layer depth map and picture insertion can be flexibly edited and printed in "WORD" (optional "EXCEL"), including mathematical statistics and hardening layer depth curve test report and saved (WORD format) (optional "EXCEL"), also can print the observed sample topography and save. The indentation and background microstructure are directly reflected, and metallographic analysis and observation are made under different magnification objective lens.
