Function and handling
The manual lathe chuck ROTA-M flex 2+2 has a centrically
compensating clamping function, which enables the clamping of
round, cubic and geometrically awkward workpieces.
The opposite jaws move centrically towards each other. The
workpiece is centered in two compensating planes that are
perpendicular to each other. Only once centering has been carried
out by both pairs of jaws will the clamping force be applied evenly
over all four jaws. Compensation is performed by several drive
rings, which are flexibly connected by ball pins. The rotary
movement of the drive rings is converted into a linear movement
of the jaws by means of a wedge bar gear.
The fine serration of the base jaws can be used to mount standard
jaws as well as special jaws for complicated workpiece shapes. The
top jaws are moved or changed in the open clamping position.
WARNING
Clamping further above the lathe chuck surface results in a
lower clamping force.
If the workpiece is released in an uncontrolled manner, there is a
risk of personal injury and damage to the system.

Functional test before use
Functional test
After installation of the chuck, its function must be checked prior
to start-up.
Two important points are:
•
Clamping force!
At max. actuation moment, the clamping force
specified for the lathe chuck must be reached. If this is not the
case, the lathe chuck needs to be lubricated.
When determining the clamping force required to machine a
workpiece, the centrifugal force acting on the chuck jaws must be
taken into account (according to VDI 3106).
If the chuck jaws are changed, adjust the stroke control to the new
situation.
