BM63.000 Series Circular Chucks
for heavy machining operations
These types of chucks exert a high and even clamping
force over the entire surface area. They are often used
on lathes, grinders, drafting and separation tables.
Positioning the piece of work is simplified by the
concentric grooves in the top plate. If required, the
chucks can be equipped with alignment edges, centering
holes, guide profiles and travelling pins. Holes of 20 mm
in steel and 6 mm in brass may be bored in the top plate
without affecting the magnetic force. The pole distribution
is 8 mm in steel and 5 mm in brass with the exception
of type BM 63.101 which has a pole distribution of
6 mm in steel and 5 mm in brass. Types BM 63.201
to BM 63.205 inclusive have 4 x M8 threaded holes,
the other types have 6 x M10 threaded holes. The
clamping force is continuously variable from zero
to a maximum of 120 N/cm2.
