Macro Vickers Hardness Testing Equipment

Automatic MacroVickers Hardness Tester AutoVicky ZHV-WH5010

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 10gm to 1Kgf, although "Macro" Vickers loads can range up to 50 Kg or more.

Introduction:

AutoVicky ZHV-WH Series is an automatic macro-Vickers hardness testing system with machine vision, motorized X-Y platform and computer software system, it is applied to test Vickers hardness scales of metals, ceramics, and composites. 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 macrostructures, 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.

Introduction of Vickers and Knoop Measuring Software

Software Advantages:

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.

Basic Function:

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

●​ Two 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.

●​ In 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).

●​ Three types of indentation marks are supported: "Rectangle", "Red Cross" and "Circular".

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

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

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

●​ Automatic switching of turret (switching of objective lens and indenter).

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

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

●​ The 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.

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

●​ All 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.

●​ Refer 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.

●​ When 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.

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

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

●​ Report content and format can be flexibly set, and WORD and EXCEL documents can be automatically generated.

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

●​ The 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.

Advanced Function:

●​ Automatic focusing function. Automatic focusing of indentation can be realized, and the focusing time of single indentation is 2-5 seconds. (To realize this function, the ZHV-VH1010 must be equipped with motor Z-axis and auto-focus system)

●​ Route planning function. As an extension of the distance measurement function, the accurate planning of 17 modes of the path to be measured is completed by clicking the image with the mouse.

1) Free point selection: click any position of the image to become the path to be measured.

2) Arbitrary direction: select any starting point and straight line segment in any direction.

3) Edge normal: click near the edge to automatically generate normal line segments.

4) Two point normal: select the two ends of the edge to generate the center normal line segment.

5) Angle bisector: three points construct angles to generate angle bisector segments.

6) Circular route: two-point centering / radius, generating a path in time.

7) Edge contour: click near the edge to automatically generate a path along the edge.

8) Edge equidistant: click the distance along the edge to generate equidistant line segments.

9) Sawtooth waveform: the period, tooth height and tooth symmetry can be set quantitatively.

10) Center of two point: select two points on the image to generate the midpoint as the path to be measured.

11) Line: click any starting point, straight line segment in any direction, and variable distance in the middle.

12) Multiline: multiline waypoints.

13) Zigzag: zigzag multiline.

14) Interpolation: insert a fixed number / distance of path points between two points.

15) Matrix: the path point of the rectangular array.

16) Wheel: wheel path point.

17) Ring: circular path point.

●​ Provide indenter / lens offset calibration function to eliminate the mechanical deviation between indenter and lens and correct the overall error of the system, so as to improve the accuracy of hardness test results.

●​ Edge scanning function. Through the movement of the XY automatic platform, the edge of the specified object can be scanned and the object edge contour can be drawn.

●​ Panoramic splicing function. Through the "panoramic scanning" function, you can obtain a panorama within a specified range and make any path planning on the map.

●​ Regional Mode & continuous testing function. For multiple indentations that may exist in the same field of view, the area mode can be selected, and only the indentations within the set range are considered during each measurement. When the area mode is turned on during continuous testing, the test interruption caused by multiple indentations in the same field of view can be avoided. Surface correction function.

●​ Surface correction function. It complies with table I and Table II of ASTM E384 standard, and provides test and correction requirements for curved parts such as balls and rods.

●​ Angle correction function. The angle deviation between the platform and the camera can be eliminated through the automatic correction of the angle, and the positioning accuracy of the platform can be improved.

●​ Fracture toughness function. The function of fracture toughness can be checked to measure indentation fracture toughness data.

●​ Multi sample panoramic splicing function. Panoramic splicing can be carried out for multiple samples at the same time, and then path planning can be done on these panoramas. Finally, the continuous testing was completed.
