the 110 mm. chromed and lapped
cutter-holder arbors with a tolerance of 2 microns ensure perfect centering of the
cutting equipment in any position. The
cutter-holder arbors are supported at one
end by pre-loaded angular contact ball
bearings (without shaft axial float). No
other support will be necessary while the
equipment is being assembled. At the opposite end the cutter-holders are supported
by needle bearings inserted in the appropriate removable bearing supports which speed
up equipment replacement.
The tungsten carbide cutters, suitably
ground on the diamond wheel, are locked
onto the arbors with tie rod blank cutter
hubs, which eliminate uneven wear of
the cutters and therefore ovalization, and
speed up setting. Other grease operated or
hydraulic lock systems are supplied on the
customers request.
