BM permanent-magnetic V-block
3965
One V-block.
3966
Two V-blocks, ground to one height in pairs.
Design: With parallel pole pitch
in enhanced magnetic design. An
especially strong, permanent-ceramic magnet system with high, evenly
distributed holding force across the whole clamping surface ensures
the deployment on lathes and grinding machines. The worked-in
centring grooves facilitate aligning the workpieces. All round chucks
can receive centring (see table, size D and H, for dimension) as
required. Machining of the upper plate without impairing the holding
force is possible up to a depth of 15 mm in steel and 7 mm in NFM
materials. The clamping force can be continuously regulated from zero
to maximum.
Holding force:
max. 120–150 N/cm
2
with ground workpiece
clamping surface.
Application:
Designed for heavy chip removal. For machining on
lathes and grinding machines.
Note:

BM permanent-magnetic round chuck
Design: With radial pole pitch.
An especially strong, high-energy
magnet system made from neodymium-iron-boron (NdFeB) with
high, evenly distributed holding force across the whole clamping
surface. The round chucks can be equipped with a through-hole
to mount centring devices and coolant supply.
Holding force:
max. 160–180 N/cm
