Motorized XY Working Table Stage Vickers Durometer Hardness Test

 

Basic Structure:

1) Touch Screen Digital Micro Vickers Hardness Tester with Auto Turret

2) Auto Control, Measurement & Data Image Processing System

 

The Vickers hardness test can be used for all metals and has one of the widest scales among hardness tests. The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with a pressure, which also has units of pascals. The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not a pressure.

 

Working Principle

After a test, the indenter will make a indentation on the surface of workpiece. Measuring the two diagonals’ length of indentation , then input the length value into machine, the hardness will show on the screen.

 

Main Applications:

DVS-1XY is mainly used for testing the Micro Vickers hardness of various kinds of ferrous or some of non-ferrous materials, spare parts (machining parts, forging parts, casting parts, steel casting parts), heat-treated parts, as well as effective hardened layer depth, coating or welding parts’ hardness of heat-effected location. It can also be used for observation of metal parts internal metallographic structure, collection, display and output print o f images.

It is especially for measuring the hardness gradient distribution curve of work-pieces.

 

Main Functions:

1. The turret with 10X and 40X objectives can realize large area specimen profile scan by low magnification and accurate hardness measurement by rotating to high magnification as per requirement.

2. The system can be used individually or as a whole, with flexibility.

3. Through automatic displacement stage controlled by built-in stepper motor and mouse clicking to have multiple control mode and realize high position accuracy, high repetition, rapid speed of movement and high work efficiency.

4. The software can control the operation of hardness tester’s hardware and realize two-way communication.

5. Double side movement of automatic displacement stage, equipped with safety device to effectively avoid the damage to the instrument by false operation.

6. The image collecting device is with rapid speed of feedback, high accuracy of automatic measurement, high repetition to improve the efficiency and accuracy of hardness measurement.

1 pixel thin testing line, with high accuracy by manual measurement.
