ABSTRACT:
The clamping system makes it possible to hold a free portion of a part during operations performed thereon. The device includes a plurality of blocks, each integral either with a pin or with a tube equipped with a small operating lever. The assembly is mounted in a gripping base between two shoulders. Gripping of each block in the clamping position is accomplished by a screw and two plates which make it possible to lock the assembly. The clamping system permits clamping of turbojet blades during the electrochemical machining or milling operation thereon.
