Automatic MicroVickers Hardness Tester AutoVicky ZHV-VH2005

AutoVicky ZHV-VH2005 is an automatic micro-Vickers hardness testing system with machine vision, motorized X-Y platform, optional auto-focus system and computer software system ATS-300, it has auto-measurement about the indentation of Vickers, eliminates human operation error, largely improves working efficiency, makes hardness testing measurement more accurate and uncomplicated.

Vickers method is based on an optical measurement system, it specifies a range of light loads using a diamond indenter to make an indentation which is measured and converted to a hardness value. It is very useful for testing on a wide type of materials, but test samples must be polished to enable measuring the size of the impressions. A square base pyramid shaped diamond is used for testing in the Vickers scale. Typically loads are very light, ranging from 5gf to 2Kgf, although "Macro" Vickers loads can range up to 50 Kg or more.

Micro Vickers hardness methods are used to test on metals, ceramics, and composites - almost any type of material. Since the test indentation is very small in a Vickers test, it is useful for a variety of applications: testing very thin materials like foils or measuring the surface of a part, small parts or small areas, measuring individual microstructures, or measuring the depth of case hardening by sectioning a part and making a series of indentations to describe a profile of the change in hardness.

1. It can realize panoramic scanning, scan the overall graphics of the product to the computer, select any position, and the product will automatically move to the required position

2. It can support 17 Ways of path planning, set any number, such as 30-point coordinates, click start, and the machine will automatically complete 30 point measurement without manual operation, automatic loading, automatic focusing and automatic measurement.

3. Equipped with optional Z-axis motor and auto-focus system, there is no need to manually find the focal length, and the machine automatically focuses. All the steps are completed by software to avoid manual measurement errors. 

ØThe automatic recognition ability of indentation image is leading, and the detection efficiency, stability and accuracy of detection results are high.

ØTwo kinds of calibration: optical calibration, (manual / automatic) hardness block calibration. The hardness block supports multiple averaging, arbitrary multiple standard blocks and segmented calibration and preferred measurement.

ØIn addition to automatic measurement, there are three manual measurement options: four side measurement, diagonal measurement and four-point measurement (the order of four vertex selection can be arbitrary).

ØThree types of indentation marks are supported: "Rectangle", "Red Cross" and "Circular".

ØDuring manual measurement, it has the function of magnifying glass, which is convenient to find the indentation vertex position;

ØThe unique keyboard shortcut function can quickly move the selected vertex to make the measurement operation more efficient.

ØProvide pixel distance and physical distance of indentation diagonal, and calculate HV / HK value under current load in real time.

ØAutomatic switching of turret (switching of objective lens and indenter).

Ø5 million digital cameras to display indentation video on the computer. It can capture and store images.

ØReal time display and update the status of current hardness tester: current indenter / objective lens, load holding time, loading force, etc.

ØThe distance between two points can be measured manually; Multiple groups of distances can also be displayed on the video or image at the same time.

ØIn case of different resolutions, different objective lenses and different loads, the software will automatically select the best calibration coefficient.

ØAll test point information can be identified and marked separately or according to customer requirements. The test point identification information will be displayed in the test value sequence table and indentation diagram for easy query. This function is very important for subsequent analysis and processing.

ØRefer to GB, DIN, ISO, ASTM and other Hardness Conversion standards to realize: Vickers HV, Knoop HK; Rockwell: HRC, HRA, HRB, HRD, HRE, HRF, HRG, HRK; Surface Rockwell: HR15N, HR30N, HR45N, HR15T, HR30T, HR45T; realize mutual conversion between hardness values such as Brinell HBS and Brinell HBW.

ØWhen measuring the hardened layer path sequence, there are multiple flexible initializations setting modes, which automatically save and import the previous path sequence; The measurement path can also be saved as desired for reloading.

ØThe path sequence measurement results automatically generate the corresponding hardened layer depth value and hardness change curve.

ØMultiple analysis modes can be selected for measurement data; All results can be set into graphic report.

ØReport content and format can be flexibly set, and WORD and EXCEL documents can be automatically generated.

ØPassword and management authority can be set: ordinary operators can only measure hardness according to the set settings.

ØThe built-in standard hardness value conversion tool can automatically convert the measured hardness value according to the table and list it in the result table.
