Setting of platform movement mode

You can click any point in the interface automatically select the point, you can set the starting position of the straight line and the location of the random movement, through the mouse click on the automatic X-Y displacement platform carrier stage for 8 directions of arbitrary movement control, speed can be adjusted, can automatically reset, can be arbitrarily reset coordinate zero

System description

Automatically complete continuous pressure, load keeping, reading, data recording, by choosing a measurement method all measurement will be automatically completed quickly;

Select straight lines, zigzag lines, circles, arcs, random points, matrices and self-learning modes according to different needs; Data processing software is used to improve the readability of non-clear indentation on non-smooth surface;

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

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

Hardness Tester control

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

You can set the brightness of the micro hardness tester's light source

Select the control objective for conversion and reflect in the software interface to calculate parameter changes

Select or start to control the durometer indenters automatically into the load position, load, hold, unload and automatically back to the measurement objective position

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

Control object platform movement mode (Patten)

The software system can control the automatic loading platform for programming and moving, which can be:

1) Measurement mode (Random A)

Use this mode to suppress and read an optional point.

2) Measurement Mode (Random B)

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

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

4) Longitudinal (Y axis direction) pressure and read

5) Measurement Mode (Line Set A)

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

6) Measurement Mode (Line Set B)

Use this mode for regular intervals of pressure and read.

7) Mobile programming methods such as trajectory coordinate movement

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

Measurement method

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

Optional manual mode measurement

Image Acquisition/recognition method

Adopt high-quality and high-resolution cameras with a resolution of 12 million and large-size original image acquisition; A variety of image compression methods are convenient to use (adopted images and measurement results for storage format, image storage format BMP, JPG and other common file formats).

Automatic Vickers indentation measurement system adopts pixel recognition technology, and analyzes indentation image through special Vickers hardness indentation analysis software, and the analysis software adopts digital image processing technology edge segmentation algorithm to extract experimental indentation edge, and then the method of extracting micro hardness indentation edge is to analyze the sampling signal of the test indentation with the wavelet multi-resolution theory, and to fit the indentation edge line with the least square method, it can quickly and accurately extract and automatically calculate the Vickers hardness value from the indentation area of the Vickers hardness test of the microstructure, and improve the readability of the non-clear indentation on the non-smooth surface.

Automatic measurement time

About 0.3sec/1 Indentation

Measuring repetitive indentation

±1.0%  (700HV/500gf)

The minimum indentation can be measured

About 5mm (automatic measurement)

Minimum unit of measurement

0.01mm

English

Data output format/

Edit function

Inspection report can be customized according to user requirements;

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

Can easily output a variety of measurement data, hardness value table, hardened layer depth, maximum, average, minimum, display and output color images with hardness value;

Hardness value, hardness table, hardened layer depth chart, image insertion and other data can be flexibly edited and printed in "WORD" (optional "EXCEL") test report containing mathematical statistics and hardened layer depth curve and saved (WORD format) (optional "EXCEL"), also can print the observed sample topography and save. The microstructure of indentation and background was directly reflected, and metallographic analysis was made under different magnification objective lens.
