Measurement room 1

Dresselhaus QS Messraum 1Low load hardness testing device. The low load hardness testing device is used to establish surface hardness, carburisation condition and hardening sequences.

Measurement room 1

Dresselhaus QS ProfilprojektorProfile projector. This optical meter works to accurately establish lengths, radii and angles. The measurement accuracy is 0.001 (a thousandth).

Measurement room 1

Dresselhaus QS Abteilung MikroskopLight microscope. Polished specimens are looked at under the light microscope in order to assess the structure and determine carburisation / decarburisation.

Measurement room 1

Dresselhaus QS Mess PrüfmittelFor measuring lengths, in addition to the test equipment mentioned above, other conventional test equipment is available such as vernier slide gauges and thread pitch gauges with indicators.

Measurement room 2

Dresselhaus QS Messraum 2Using this universal testing machine, it is possible to carry out full tensile tests / tensile tests on screws and milled specimens up to a load of 600 kN as well as test load trials on nuts.

Measurement room 2

Dresselhaus QS Abteilung SchraubenprüfstandUsing this test equipment, the screw-in properties for screw connections are worked out in accordance with VDI 2230. This is done by determining selected parameters: Pretension force, locking torque, angle of rotation and friction coefficients.

Measurement room 3

Dresselhaus QS Messraum 3Using a nebuliser, a neutral salt spray test is performed in order to establish the corrosion resistance of metallic surfaces.
