2.5 Collets
2.5.1 Application
The adaptation of the tool is executed via collets type PGR and/or PGR-GB. These
powRgrip
collets have a taper shank with plane contact surface and a central bore for the
tool shank. With collets type PGR the tool is centred and clamped via the clamping diameter,
the shank tolerance must be h6. With collets type PGR-GB the torque arising during the
thread producing operation is additionally transferred via the square, integrated in the collet;
tools with shank tolerance h9 may be used.
The powRgrip
collets have an integrated adjusting screw. With a pre-adjustment tool the
length of the tool system can be pre-adjusted.
Owing to the better torque transmission and the possibility to use tools with shank
tolerance h9, we would recommend the use of collets type PGR-GB.
The collet sizes for the according collet holders may be taken from table 1, page 5. The
clamping diameter is indicated by the tool used.
2.6 Assembly instruction for the collets and tool
Do not press in the collet without a tool!
Pressing in collets without a tool will destroy the collet!
Before clamping, clean and degrease collet and cutting tool as described in the
cleaning directions!
Dirt and grease reduce clamping force, accuracy and tool life.
