AHVST-1000ZXY Automatic micro Vickers hardness tester

materials

introduce

Pressure control

When the test force of the hardness tester is converted, the system senses the change of the test force and displays it in the system in real time.

Turret control

The software controls the hardness tester to switch between the objective lens and the indenter without manual control of the hardness tester.

Load control

The software controls the hardness tester to load, without manual control of the hardness tester.

Measurement control

The software controls the hardness tester turret, loads and directly reads the Vickers hardness value

Software control hardness tester Z axis rising and falling

Z axis control

The software controls the Z axis of the hardness tester to rise and fall.

Auto focus control

The software controls the Z axis of the hardness tester to automatically focus to find the clearest point on the surface of the product.

Light source brightness control

Set the brightness of the light source

Image Acquisition

Real-time display of hardness images, images can be stored, printed, and printed at fixed times.

Manual/automatic measurement

Manual: pull diagonal measurement, two-point card line measurement, four-point measurement, automatic: automatically find the four vertices of the indentation, fast speed, accurate data. Continuously hit and measure, hit and measure immediately, and suppress by designated coordinates.

Hardness conversion

According to Chinese standards, automatic conversion of Brinell-Rockwell-Vickers-Knoop hardness values, real-time display, and conversion to various international standards

Graphic report

Automatically record the measurement data, automatically generate the hardness-depth curve, save or print the hardness-depth curve and all indentation measurement values; save or print the indentation image and the current indentation hardness value;

The inspection report can be customized according to user requirements; through the data processing software, the hardened layer depth value formed after continuous measurement of the sample can be displayed in the form of a table; various measurement data, D1, D2, hardness value table, hardened layer depth, Maximum value, average value, minimum value, display and output each indentation picture. Data such as hardness value, hardness table, hardened layer depth map and picture insertion can be flexibly edited and printed in WORD or EXCEL to print out a test report containing mathematical statistics and hardened layer depth curve and saved in WORD format or EXCEL, and the observed samples can also be printed The topography map is saved and directly reflects the microstructure of the indentation and background,

Knoop measurement

Replaceable Knoop indenter for automatic Knoop hardness measurement

Auto Z axis

Auto-focusing step (μm): The moving step of the Z-axis during auto-focusing, the default is 1.25μm.

Z axis key step distance (μm): keyboard or interface direction key button Z movement distance, the default is 1.25μm

Z axis rising and falling: Low speed (mm/s): Default 0.0625mm/s. High speed (mm/s): Default 1.0mm/s. Speed is adjustable.

Automatic loading table

The point can be automatically selected by clicking any point in the interface with the mouse, and the start position of the straight line can be set and the random moving position can be set. The automatic XY stage stage can be controlled by the mouse to move arbitrarily in 8 directions, and the speed can be adjusted. It can be reset automatically, and the coordinates can be cleared at will;

The software system can be programmed to control the movement of the automatic stage, and the system provides 14 modes:

1) Along the line; 2) With an angle along the line; 3) Free click;

4) Along the horizontal line; 5) Along the vertical line; 6) Multiple lines along the curve;

7) Matrix along the curve; 8) Arc; 9) Tooth center;

10) Tooth tops are parallel; 11) Automatically along the edge with angle; 12) Automatically along the edge matrix;

13) Center of circle; 14) Parallel to multiple tooth tops along the curve.
