Spiral Ring Chuck Three and four-jaw chucks, geared scroll chucks, DIN 6350, self-centering
A proven and universal suitable clamping system
- finds it's application wherever a high clamping
force, high runout accuracy and very high
repeatability are required (i.e. lathes, turntables,
circular indexing tables etc.) The radial and axial
runout precision correspond to DIN 6368 Part 1
Precision Class 1 (High precision chucks).
Particularly flat design with direct mounting.
Clamping force transmitting system
The jaws can be moved across the entire clamping range by turning a key.
This advantage allows the quick clamping of different workpiece diameters
without changing or shifting the jaws.
Mechanism
The radial positioned
Pinion (4) transmits
the power via a bevel
gearing to the Spiral
Ring (3), where the
spiral transmits it to
the Jaws (6). Steel
or cast iron body (1),
Cover (2)
Lubrication
The chuck has to be
lubricated at regular
intervals with our
special grease F80
to maintain its
practical value as
long as possible.
