A and A+ models of the Qness 250/750/3000 EVO hardness tester series are the pinnacle of automated hardness testing.
Due to the fully automated 3-axis-control samples with different test heights can be tested. Samples can be clamped safely with up to 3.200 kg by the powerful asynchronous motor of the Z-axis.
XLED illumination modules revolutionize the analysis of Brinell indentations. Due to beading on commercially available lenses, soft Brinell indentations in particular can be subject to imprecise gauging results. In contrast, XLED lenses guarantee precise and repeatable measurements, regardless of material type and hardness, due to direct and wide-extension illumination.
The optics system of the new hardness tester series EVO has been completely redeveloped. It was built on site in the cleanroom at the QATM plant and benefits from the company’s comprehensive expertise. All hardness testers of the new series share one universal microscope system covering all the necessary visual ranges between 0.1 mm and 8 mm in maximum clarity and contrast. The QATM system guarantees uniform illumination across the entire image, regardless of the degree of magnification, and without dark edges.
High-quality CMOS 5-megapixel cameras with Ethernet data transfer define the current industrial standard. Unlike other camera systems, a far higher transmission stability is possible here. Additionally, the PC and hardness tester can be set up remotely at great distances from each other. This is ideal in manufacturing environments in which the control infrastructure is installed in external switch cabinets.

Ultimate ease of use with 5 megapixel colour camera for recording the entire sample for a perfect overview and documentation in the protocol. As standard, hardness tester versions CA+ and A+ record the entire table surface as sample image.
Edge recognition involves automatic adaption of test row starting points to the sample edge when using project and sample templates. The module significantly increases the degree of automation and is an ideal add-on to the serially provided Auto- Snap function.
The easy way to serve universal applications: The sophisticated tool-changer concept with a rotational axis angle of 15° provides space for 8 tools in a uniquely compact unit. Downholder elements with a closed shape on three sides guarantee secure workpiece clamping around the test point – even for small test pieces.
Fully automatic and robust XY slide with high-precision positioning drive. Dynamic joystick to control all 3 axes (XYZ). Usable support surface 450 x 300 mm or, on request, larger travels and test tables available.
For each XY test point position the Z height can be individually selected. During automatic testing, the machine changes between specimens of different height or different test levels safely and fully automatically. Thanks to the innovative CAS technology, the unit is protected against collisions. When testing clamped samples, the patented QATM “workpiece recognition” reduces the approach speed of the test head automatically via sensor detection (preserves machine and sample).
High-performance induction motor in the A/A+ version facilitates a workpiece clamping force of up to 3.200 kg. Clamping power is adapted to the test method and is automatically set to be greater than the test force. Operators do not need to set levels and can rely on the hardness tester to guarantee safe, optimized adaption.
Qness 250 A/A+ EVO-Version only: For hardness tests according to Rockwell or Brinell, parts securely fixed with the downholder are indispensable. For general processes, such as edge recognition or during the programming of test samples, however, the downholder is not required. Hence, the downholder clamp can be swivelled in or out by motor in a matter of seconds between different processes in the innovative EVO system. This improves operating convenience and further reduces cycle times.
An entire range of relevant data, such as test patterns, test methods and user fields can be activated via pre-defined sample magazines. QATM can provide the most suitable clamping setup, matrices and cassette systems for every requirement.
Intuitive, clearly organized and professional: Qpix Control2 is a next-generation software for Brinell / Knoop / Vickers hardness testers, developed based on customer feedback and input for maximum user-friendliness. The controlled test head benefits from automatic height adjustment and contactless exploration, complete integration of the sample holder, CAD compatibility with 3D imaging and a whole range of easily understood 3D control elements and views included in the software. It sets new standards in hardness testing.
Identical samples can be set up in the software in scale as a 3D model.
Innovative Collision Avoiding System (CAS) technology protects the mechanical parts in the device using predictive 3D motion calculations to visualize the effects of collisions and operation errors.
Qconnect is the interface in QATM Qpix Control2 software, providing customers with a full portfolio of inter-device connectivity - from serial production, open XML interfaces (bi-directional) and pre-specified plug-in solutions, such as the QDAS Plug-In+, through to customer-specific connectivity solutions implemented completely by QATM. We have a professional solution for every applicational requirement.
Switchable industrial magnets enable power- and time-saving loading and unloading of the test system and, at the same time, guarantee a secure hold during the test. In addition, all QATM fixtures can be equipped with a sample holder recognition: via integrated sensors, the fixture is automatically recognized by the testing device and only the appropriate test programs are loaded.
Individual planning and professional project handling
The swivelling test piece support permits testing of samples even if the testing surface is not parallel to the support surface.
Up to 8 samples can be placed in the Jominy sample holder for testing with the additional Jominy test module. The testing cycle is fully automated and executed according to the norm. Larger sample holders are available on request.
A or A+ models of the macro hardness tester series EVO allow testing tubes and tube segments fully automated and with maximum throughput according to valid standards.
