Micro Vickers Hardness Tester For Case Depth Testing Complete Equipment Configuration
Micro Vickers Hardness Tester For Case Depth Testing: Complete Equipment Configuration
A Micro Vickers hardness tester for case depth testing is used to measure hardness changes from the surface to the core of carburized, nitrided, induction-hardened, carbonitrided, coated, and surface-treated metal parts. A complete configuration should include low-load testing capability, optical measurement, XY stage, profile software, sample preparation equipment, calibration blocks, fixtures, and report export functions.
Low-Load Testing
Micro HV loads help measure thin hardened layers and small surface-to-core profiles.
XY Stage
Precise point spacing is important for case depth curves and repeatable profile testing.
Sample Preparation
Cutting, mounting, grinding, and polishing directly affect indentation clarity.
Profile Report
Software can export hardness profile curves, images, values, and case depth results.
Why Case Depth Testing Needs A Micro Vickers Solution
Case depth testing is used to verify whether the hardened layer of a metal part reaches the required depth and hardness gradient. It is commonly required for carburized gears, nitrided shafts, induction-hardened tracks, carbonitrided fasteners, tool steel parts, bearing components, molds, pins, rollers, and surface-treated precision parts.
Surface hardness alone cannot prove that a heat treatment process is correct. A part may show a good surface HRC value but still fail if the hardened layer is too shallow, too deep, uneven, or not properly connected to the core hardness. This is why Micro Vickers hardness testing is widely used for surface-to-core hardness profile measurement.
A complete Micro Vickers case depth testing solution is not only one machine. Buyers should also confirm sample preparation equipment, low-load range, microscope quality, XY stage, software curve function, calibration blocks, fixtures, and report export before ordering.
1. Micro Vickers Tester With Suitable Load Range
The core equipment is the Micro Vickers hardness tester. For case depth testing, the tester must support suitable low-load Micro HV testing. The required load depends on the layer thickness, material hardness, test standard, indentation size, and distance between test points.
If the load is too high, the indentation may be too large and may not reflect the thin hardened layer accurately. If the load is too low, the indentation may become difficult to measure, especially if the sample surface is not polished well. Buyers should confirm the required Micro HV load range before quotation.
| Application | Testing Purpose | Configuration Checkpoint |
|---|---|---|
| Carburized gears | Measure effective case depth from tooth surface to core | Micro HV load range, profile software, precise XY stage |
| Nitrided shafts | Inspect thin nitrided layer and hardness gradient | Low-load capability and clear optical measurement |
| Induction-hardened parts | Check hardened zone depth and transition to core | Cross-section preparation and test path control |
| Coated or surface-treated parts | Measure thin layer hardness with reduced substrate influence | Low load, edge retention, polishing quality, image measurement |
2. Optical System And Vision Measurement Software
Micro Vickers case depth testing depends on measuring small diamond-shaped indentations. The optical system and vision software must be able to capture clear indentation images and calculate hardness values consistently. Poor image quality can cause unstable results even when the mechanical loading system is correct.
For factories that need customer reports, automatic or semi-automatic vision measurement software is strongly recommended. It can save indentation images, calculate values, record test points, generate hardness profile curves, and export PDF or Excel reports.
Vision software should support:
Indentation image capture.
Automatic or assisted diagonal measurement.
Micro HV value calculation.
Test point coordinate recording.
Surface-to-core hardness profile curve.
Effective case depth calculation when required.
Image storage for customer review.
PDF and Excel report export.
Sample ID, batch number, operator, and inspection date records.
3. Manual Or Motorized XY Stage For Test Point Control
Case depth testing requires multiple indentation points from the surface toward the core. The distance between points should be controlled carefully. A high-quality XY stage helps the operator position test points accurately and repeat the same test path across multiple samples.
For basic labs, a manual XY stage may be enough. For higher-volume testing, automated profile testing, or strict customer reports, a motorized XY stage can improve efficiency and reduce positioning variation.
| Stage Type | Suitable For | Main Benefit |
|---|---|---|
| Manual XY stage | Low-volume case depth testing and basic QC labs | Lower cost and flexible manual operation |
| Precision manual stage | Labs needing better point spacing control | Improves repeatability of surface-to-core test paths |
| Motorized XY stage | High-volume labs and repeated hardness profile testing | Reduces manual positioning time and operator variation |
| Software-controlled stage | Advanced case depth and automated profile reports | Records coordinates and supports automated testing workflow |
4. Sample Preparation Equipment Is Not Optional
Case depth testing usually requires a prepared cross-section. The sample must be cut through the required area, mounted, ground, polished, cleaned, and checked before Micro Vickers testing. If the sample surface is scratched, rounded, overheated, or poorly polished, the indentation may be unclear and the hardness profile may be unreliable.
Many buyers only ask for the Micro Vickers tester price, but later discover that they also need sample preparation equipment. For a complete case depth testing lab, cutting, mounting, grinding, polishing, and microscope inspection should be considered together.
| Equipment | Purpose | Why It Matters For Case Depth |
|---|---|---|
| Metallographic cutting machine | Cuts through gear teeth, shafts, fasteners, or treated layers | Avoids heat damage and deformation before testing |
| Mounting press or cold mounting tools | Supports small or irregular cross-section samples | Improves edge retention and protects thin hardened layers |
| Grinding and polishing machine | Creates flat, scratch-controlled sample surface | Makes indentation edges clear for reliable measurement |
| Metallurgical microscope | Checks layer, structure, and surface preparation quality | Helps confirm correct test path and prepared area |
5. Calibration Blocks, Indenter And Accessories
A Micro Vickers hardness tester must be verified with suitable Micro HV calibration blocks. The block should match the load and hardness range used in daily testing. Buyers should also confirm the Vickers diamond indenter, objective lenses, sample holders, XY stage accessories, software license, computer, and report export tools.
For case depth testing, the quotation should not only list the tester. It should clearly include all required accessories and consumables, especially if the buyer is building a new QC lab.
Recommended accessories include:
Micro HV calibration blocks.
Vickers diamond indenter.
Objective lenses for indentation measurement.
Manual or motorized XY stage.
Mounted sample holders.
Camera and vision software.
Computer and monitor if required.
Grinding paper, polishing cloth, and diamond suspension.
Operation manual, training, warranty, and technical support.

Do customers require PDF reports, Excel data, indentation images, or hardness profile curves?
Conclusion: Case Depth Testing Requires A Complete Lab Workflow
A Micro Vickers hardness tester is the key equipment for case depth testing, but reliable results depend on the complete workflow. Buyers should confirm low-load testing capability, optical measurement, XY stage, vision software, sample preparation, calibration blocks, indenter, fixtures, and report export functions before ordering.
For carburized gears, nitrided shafts, induction-hardened parts, coated samples, weld sections, and surface-treated components, the best solution is usually a complete package: Micro Vickers tester, case depth software, XY stage, metallographic cutting machine, mounting system, grinding and polishing machine, microscope, calibration blocks, and report tools.
If your factory needs case depth testing for heat-treated or surface-treated metal parts, send your sample photos, process type, expected layer depth, Micro HV requirement, and report format before requesting a quotation. A complete configuration can help avoid missing equipment and unreliable results.
