QATM - Hardness Testers - Macro Hardness Testers

The characteristic "C" shaped machine frame gives the CS and C versions of the Qness 250/750/3000 EVO series their name.

The proven concept with fixed test head and up/down moving spindle has been standard in hardness testing for many decades and is ideally suited for small test pieces - as model "C" for component heights up to a maximum of 395 mm and as an even more compact model "CS" with 175 mm maximum test height.

QATM redefines universal hardness testing with the EVO models: extremely short cycle times and maximum precision were the main focus of product development.

Key features

• Test table height adjustment: Via stable, ultra-precise roller-bearing spindle guide. Solid, no-maintenance structure with a sophisticated black chrome-plated handwheel. All devices are available with a Ø25 mm table mount (optional ¾" adapter available).

• Swiveling downholder: No long tool changeovers for inaccessible test positions. The downholder can be swivelled in and out via manual or motorized action, as required. Furthermore, the clamping elements can be changed easily and adapted to suit the customer‘s component.

• Wide range of test tables and prism anvils: The wide range of available test anvils and prisms enable hardness testing to be conducted on unusually large or spherical items, and on test objects with an uneven test surface.

• 2-Position tool holder: All Qness 250/750/3000 EVO devices are equipped as standard with clamping for 2 tools – simple and affordable with room for a test head and a lens or XLED - ideal for unchanging testing requirements.

• Rapid indenter changing system: Uniquely simple, tool-free indenter changes due to indenter quick-release mechanism. 

The fixed component support and the extra-large test table area of the "M" version allow hardness testing of even the largest components.

The test head is moved manually by turning the hand wheel on the front of the machine.

The bearing of the test head is designed for particularly smooth running and allows operation with minimum effort. The maximum test height is 510 mm.

Key features

• Swivel-action machine table: Unique operating convenience for large, awkwardly-shaped molded and formed components and workpieces. The work table, optional with the M and E versions, can be tilted up to 5° - including built-in grips - no extra workpiece clamping necessary!

• Swiveling downholder: No long tool changeovers for inaccessible test positions. The downholder can be swivelled in and out via manual or motorized action, as required. Furthermore, the clamping elements can be changed easily and adapted to suit the customer‘s component.

• Enlarged test height: If the 510mm height of the test room is still not enough for especially large, bulky or difficult-to-clamp items, on request QATM can provide an even taller machine frame. The robust steel frame can be produced in customized dimensions.

A hardness tester for all purposes: no matter if operated in a laboratory or in a rough production environment.

The fixed component support and extra-large test table area allow hardness testing of even the largest components.

In the "E" version, the test head is conveniently and dynamically controlled by the integrated asynchronous motor. Test pieces of virtually any size, weighing up to 3500 kg, are securely clamped in the device. The maximum test height is 510 mm.

• Swivel-action machine table: Unique operating convenience for large, awkwardly-shaped molded and formed components and workpieces. The work table, optional with the M and E versions, can be tilted up to 5° - including built-in grips - no extra workpiece clamping necessary!

• Swiveling downholder: No long tool changeovers for inaccessible test positions. The downholder can be swivelled in and out via manual or motorized action, as required. Furthermore, the clamping elements can be changed easily and adapted to suit the customer‘s component.

• Dynamic height adjustment: The dynamic height adjustment enables comfortable positioning control via potentiometer (8 mm/s). Using the 2-hand-safety device allows a moving speed of up to 17 mm/s (included with E variant).

• Workpiece recognition: Workpiece recognition with motorized height adjustment facilitates a high test head movement speed of 17 mm/s. Sensor technology enables the workpiece to be recognized and the bracing speed to be reduced accordingly to protect the device and workpiece.

• Maximum clamping safety: High-performance induction motor in the E version facilitates a workpiece clamping force of up to 3500 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 device to guarantee safe, optimized adaption.
