SPANNTOP chuck combi deadlength 3 5 6 For this type the clamping head is coupled in the chuck and there is no axial movement. Tension is introduced through the axial movement of the connecting sleeve. Thus the work piece is clamped radially without axial movement. An interior base end-stop, or a front end-stop mounted on the front side, can be used here as well. SPANNTOP combi deadlength can be used ■ as through-bore chuck for bar work ■ as end-stop chuck for chuck work ■ for work pieces with a very short collar 1 7 2 4 1 flange 2 chuck body 3 connecting sleeve 4 clamping head 5 torsional safety 6 mounting threads for front end-stop 7 changeable base end-stop [can be fixed from outside via 3 screws] The advantages ■ radial clamping without axial movement of the clamping head ■ clamps work pieces on a short collar or shoulder ■ converts to a fully functional »bar chuck« when the end-stop plate is removed ■ excellent concentricity after clamping head change [< 0.02 mm] 8 SPANNTOP chuck .

The example shows a situation where the right chuck clamps the part, which is then cut off. pull-back deadlength Typical clamping and processing examples A work piece with narrow collar must be clamped. Long work piece is pulled forward several times out of the left chuck and reprocessed. Thanks to radial clamping only the axial clearance to the grooves is better maintained. Work piece transfer with narrow collar is an ideal application. short clamping surface SPANNTOP Chuck . Combi deadlength 9
