Three-Jaw Chuck for hexagonal tubes

Just as you can clamp a square or machine an eight-edge with the four-jaw chuck, you can quickly and easily machine hexagonal tubes or bar materials with the milling machine using our small three-jaw chuck. Furthermore, you can mill openings and cut-outs on the outer surfaces of the hexagonal tubes, for example, as well as applychamfers or drill holes.

A small Three-Jaw Chuck with a large clamping width

Despite its small size, this three-jaw chuck has a wide clamping range for inside or outside clamping. Consequently, you can clamp parts of approximate 1,5 mm – 70 mm outside and about 25 mm – 70 mm diameter in the inside.
A four-jaw chuck is also available for each of our CNC milling machines.

Small tool science

Lathe chuck is the name given to the chuck on wood lathes and turning lathes. These jaw chucks are centric clamping, and when you turn the jaws together or apart, they ensure that the workpiece is clamped evenly in the direction of the turning axis.

Basic equipment of a lathe chuck

The basic equipment of an industrial three-jaw chuck always includes the chuck key (usually in the form of a square key) and a set of jaws for drilling and a set of jaws for turning. On the one hand, the boring jaws are stepped from the inside to the outside (usable for bar materials). And on the other hand, the turning jaws, from the outside to the inside. Thus, allows the machining of workpieces with large outside diameters.
