Rockwell hardness tester Qness 250 / Qness 750 / Qness 3000 E EVO

BrinelluniversalKnoop/Vickers

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. FASTER TEST METHOD CHANGE-OVER Brinell, Knoop, Rockwell or Vickers hardness testing? The sophisticated tool-changer concept with a rotational axis angle of 15° provides space for 8 tools in one 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. 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. 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.
