HVS -- AXYZF Automatic Vickers hardness measurement and control system
Automatic loading platform Automatic focusing Automatic measuring indentation HVS-AXYZF Automatic (micro) Vickers hardness automatic control and
measurement system is a computer automatic measurement and control
system independently developed by our Company (software
registration certificate No. : 2016SR176822), and various types of
Vickers hardness tester (including micro Vickers) seamless
connection, forming a perfect set of automatic vickers hardness
tester measurement system. The automatic system composed of the system and hardness tester,
without human intervention, can achieve multi-sample, multi-point
hardness automatic measurement. X and Y move automatically; Panoromic scanning Automatic edge Z-axis automatic focusing; Automatic indentation measurement Generate inspection report automatically The automatic hardness measurement is mainly used for vickers
hardness measurement of various metals and some non-metallic
materials, and can be used for hardness measurement of various
metal parts and parts after thermal treatment.It is also suitable
for the determination of effective hardening depth, coating and
heat affected parts of welding parts.It can also be used to observe
the metallographic structure of various metal parts and collect,
display and print the image. The system is especially suitable for measuring the surface
hardness, hardness gradient distribution curve and effective
hardening depth of heat-treated workpiece. - Technical parameters
- 5-megapixel camera provides sharp images.
- Lenovo or Dell, operating system: Windows 10
- High precision automatic X-Y loading platform
