With unhardened top jaws or special jaws, the permitted ro-
tational speed for each machining task needs to be calcu-
lated in accordance with VDI 3106 and the maximum oscil-
lation speed must not be exceeded. The theoretically com-
puted values must be checked by a dynamic measurement
using a clamping force measuring device.
3.5 Clamping force speed diagram
The clamping force-speed diagrams refer to a 3-jaw chuck.
The clamping force / speed curves were obtained using hard
jaws. For this, the maximum actuating force was introduced
and the jaws were set flush with the outside diameter (OD)
of the chuck.
Here, the chuck is in perfect condition and is lubricated with
HAINBUCH special grease.
These diagrams cease to be valid if changes are made to
one or more of these requirements.
