How does the patented quick adjustment of the clamping width work on the Bull pneumatic Machine Tool Vise?

The locking lugs on the spindle of the Bull Pneumatic Machine Tool Vise can be turned downwards by 180° by hand.
The movable jaw can then be moved and locked in the desired position.
Adjustment to within approx. 1 mm of the workpiece is done with the Allen key supplied.

Why does the Bull Pneumatic only need 1 compressed air hose?

With the Bull Pneumatic Machine Tool Vise, compressed air is only needed for clamping.
Opening takes place via a spring return integrated in the spindle.

How is the compressed air connected to the Bull Pneumatic Machine Tool Vise?

The compressed air is connected either at the front or at the side of the connection cover (thread G1/8").

What variants of the Bull Pneumatic Machine Tool Vise are available?

The Bull Pneumatik Machine Tool Vise can be supplied with block jaws or stepped jaws and optionally with 3.5 mm or 5 mm clamping stroke. Thus, 4 variants are available.

What about clamping reliability in the event of compressed air loss?

Installing a check valve in the compressed air line prevents the clamping force from dropping.

What is the advantage of the tension clamping system for the Bull Pneumatic Machine Tool Vise?

Due to the tension clamping system on the Bull Pneumatik Machine Tool Vise, only a small part of the forces are transmitted via the base body.
This means that there is almost zero deflection and thus the accuracy of the machined workpiece is dramatically increased.
