Abstract

The present mechanical chucking device especially for a testing apparatus, has a friction reducing layer interposed between the clamping members and a base plate and another friction reducing layer interposed between the base plate and securing elements for the clamping members, whereby said clamping members may slide within a given range along the base plate without having to release the securing elements holding said clamping members to the base plate. The clamping members are driven by a spindle movably held in a guide block on the base plate which allows an exact concentric clamping of the sample.
