Concentric positioning and clamping elements
double acting
max. operating pressure 500 bar
Concentric positioning and clamping with two or three-jaw chucks on stationary fixtures is nothing new. In many applications, however, it is not possible to place the relatively large chuck bodies on the fixture. Often the smaller clamping strokes are an additional obstacle.
In our development, the individual parts can be connected to a two or multiple-element version. In the multiple-jaw version, each pair of jaws clamps independently of the remaining ones, thereby concentric clamping is obtained.
The opening can be determined by means of a connecting bar. The clamping strokes of the several sizes are designed such that manual or automatic loading and unloading can be effected also to clamp blanks with large tolerances. Also single-acting elements are available on request.

Concentric positioning and clamping elements H4.300
The flexible clamping unit is used to clamp bars which can be machined in every position, e.g. drilled, milled, threaded, etc. In conjunction with a pneumatic two-jaw chuck the rotary indexing table is used to determine the machining position of the workpiece.
The two-jaw chuck and the right-hand concentric clamping element keep the bars in the exact working position. The floating clamping element in the centre supports the bar. For this purpose it must work in a floating way, that means without centring function, what can be obtained by omitting the connecting bar. (Available on request)
