Can Micro Vickers Hardness Tester Carry Out Multi-point Continuous Testing?
Read：0
Many customers ask whether micro Vickers hardness tester support continuous testing of multiple indentation points. The answer depends on the configuration of the machine: manual models only support single-point testing; semi-automatic and fully automatic vision micro Vickers hardness testers can realize multi-point continuous testing.
1. Different Functions According to Machine Configuration
① Manual Micro Vickers Hardness Tester
No motorized XY test stage, no automatic positioning function. The operator needs to manually rotate the micrometer to move the sample stage, complete positioning, loading and measurement point by point. It cannot realize automatic multi-point continuous testing. Suitable for small-batch, simple sampling inspection.
② Semi-automatic Micro Vickers Hardness Tester
Equipped with motorized XY working stage and measurement software. Users can preset multiple test coordinate points in the software in advance. The stage automatically moves to each position sequentially, automatically applies load and measures indentation. It realizes unattended multi-point continuous testing, and all hardness data is automatically saved and exported.
③ Fully Automatic Programmable Micro Vickers Hardness Tester
Supports more powerful continuous testing functions:
Custom linear, rectangular array, circular multi-point test paths
Programmable sequence of test loads
Automatic focus, automatic indent recognition, automatic calculation of HV values
Automatic generation of test reports, statistical maximum, minimum, average and deviation
Ideal for batch specimen cross-section detection, coating hardness test, carburized/nitrided layer depth profile testing.
2. Typical Application Scenarios for Multi-point Continuous Testing
Hardness gradient test on cross-section: continuously test multiple points from surface to substrate for carburized layer, nitrided layer, thermal spray coating
Batch sampling inspection: multiple sampling points on the same workpiece to evaluate hardness uniformity
Quality inspection of PVD coating, electroplating layer: multiple positions verification to judge coating consistency
Metallographic specimen hardness mapping test
3. Key Advantages of Automatic Multi-point Continuous Test
Avoid manual repeated operation, greatly improve testing efficiency
Reduce human error caused by frequent manual positioning
Uniform test spacing, standardized test process, conform to ISO 6507 and GB/T 4340.1
All data traceable, convenient for export and quality archive
4. Frequently Asked Questions
Q: Can continuous multi-point test be upgraded on an existing manual micro Vickers hardness tester?
A: Generally cannot be upgraded. The continuous testing function relies on motorized XY stage and supporting control software, which need to be configured when ordering.
Q: How many points can the automatic model test continuously at one time?
A: There is no fixed upper limit. It can set dozens or even hundreds of test points according to test requirements, limited only by the travel range of the working stage.
Foosean provides multiple series of micro Vickers hardness tester. Semi-automatic and fully automatic vision types are equipped with motorized XY stage to support multi-point continuous testing, automatic data recording and report output, perfectly matching coating hardness test, surface hardened layer and mass metal material hardness inspection.
