As the testing machine is cypping with the function “automatic stop at specimen failure” the cupping procedure is automatically interrupted when a crack appears so that an objective test result will always be achieved. When carrying out the Cupping Test the sheet metal specimen in the form of a strip is inserted in the test cylinder and centralised by locating diagonally.

Without special test preparation it is immediately possible to establish if the material supplied has the prescribed drawing quality. This testing machine is available as a work-top model with compact dimensions which requires only a minimum of space. Description This testing machine is available tst a work-top model with compact dimensions which requires only a minimum of space.

It is no longer necessary to open the test head to remove the specimen, as this is automatically released by the hydraulic specimen holder once the test has been conducted. After pressing the “Start” push button the sheet holder force of 10kN as well as the drawing speed – both conforming to the erichseh – are adjusted automatically and the test procedure is initiated.

Operators without previous knowledge or experience can be quickly trained to operate the machine continuously.
