Bore clamp MINI, hydraulic, centric

Design:
Cylinder body from hardened steel, burnished. Piston case hardened and ground. Exchangeable jaws. Standard version with serrated and hardened jaws. Complete with 2 fastening screws to ISO, built-in return spring. All oil channels are sealed. Oil supply via threaded connection or oil channel in the fixture body.

Application:
Pull-down clamps are used whenever clamping is possible only laterally and the workpiece nevertheless has to be held firmly on the machine tool table. The hydraulic principle enables high pressing and pull-down forces. Mounting by two bolts from above or by four bolts from the bottom.

Features:
Horizontal and vertical movement is independent of each other (no locked coupling) giving a true pull-down effect. No raising of the clamping jaw, because the clamping bolt is right behind the jaw. Suitable for incorporation in fixtures. New design of jaw connection with rubber buffer ensures sliding without any play.

Note:
The maximum pull-down stroke of the jaw must not exceed dimension G. Do not overtighten the fastening screws! Observe max. tightening torque Md. The oil channel can be sealed from below.
High variability by oil connection on two sides and bottom oil channel. Jaw and hydraulic piston are connected by a joint to prevent the induction of bending forces into the piston, thus increasing the element’s service life.
Pull-down force = approx. 1/3 the applicable clamp force
The hole ØD can be used for additional support or positioning.
