A process for the determination of the force chak reason of a device for magnetic attachment of werkst} (see fig. 5).

摘要

A method of determining the force characteristics of a device for magnetic fixation of parts positioned on the upper plate (3) of the device where the part (1) interacting with the source of the magnetic field is connected to a force pickup (2) and moved along the upper plate (3) along the testing line (4). The source of the magnetic field is permanently switched on during the test whereas the part (1) is positioned in parallel to the plate (3) with a gap defined by the sensibility of the force pickup (2) and continuously moved along the testing line (4) so as to maintain the value of the gap essentially constant.
