Expandable chuck

Internal clamping sleeves with double taper are
suited to internal clamping of pre-machined
parts. Because these have tapers and slots at
both ends, the clamping sleeve is able to open
in various different ways and securely hold
workpieces in the bore which have cylindrical
faults.

Expandable chuck - ø 8 - 235 mm, ø 1.5 - 5 mm | T-EP series

Use: turning, grinding, balancing and inspection operations
High degree of expansibility 1.5 to 5 mm depending on the diameter of the sleeve
Possibility to clamp worpieces with diameters ranging from 8 to 235 mm
Clamping takes place as follows :
the worpiece is placed in the centre of the sleeve,
and the workpiece and sleeve are slid together
until they are lightly clamped, then the rear end
of the tapered arbor is struck against a piece of wood
to obtain tighter clamping.
To separate the workpiece from the sleeve,
hold the workpiece and sleeve in one hand
and strike the smaller end of the arbor.

Expandable chuck - ø 5.5 - 79.7 mm, ø 0.5 - 1 mm | T-EPN series

Use: turning, milling, grinding, shaving and inspection operations
Expansibility 0.5 to 1 mm depending on the diameter of the sleeve
Possibility to clamp worpieces with diameters ranging from 5.5 to 79.7 mm
The slotted sleeve has a collar contained within a knurled ring. This collar acts as a workstop, positioning the workpiece axially on the mandrel
The workpiece is clamped by tightening the sleeve with the knurled ring. The movement of the sleeve up the tapered arbor expands the sleeve, ensuring that the workpiece is clamped tightly.
The movement of the sleeve in relation to the tapered arbor guarantees that the workpiece is positioned against the workstop.

Expandable chuck - ø 14.7 - 101.7 mm, ø 1.5 - 2 mm | T-MEP series

Use: turning, milling, grinding, shaving, gear cutting and inspection operations
Expansibility 1.5 to 2 mm depending on the diameter of the sleeve
Possibility to clamp worpieces with diameters ranging from 14.7 to 101.7 mm
Clamping is effected by tightening the nut connected to the sleeve, which pushes the sleeve onto the tapered arbor.

Expandable chuck / morse taper shank - ø 14.7 - 82.7 mm, ø 1 - 2 mm | TMCM series

Use: turning, milling, grinding gear hobbing, balancing and inspection operations
Expansibility 1 to 2 mm depending on the diameter of the sleeve
Possibility to clamp worpieces with diameters ranging from 14.7 to 82.7 mm
The workpiece is clamped when the sleeve is pushed up onto the tapered arbor
by tightening a screw, inserted into the sleeve from the front, using a key.
The workpiece stop on the mandrel, positions the workpiece axially, either directly or by means of a cross bar with perfectly parallel surfaces
