DUOPLUG
®
connection for maximum pre-
cision and concentricity
uu
stronger retention forces
uu
machining in deep cavities also with ver-
tical walls
uu
roughing operations with maximum re-
tention forces
uu
finishing operations with very high requi-
rements for surface finish
uu
up to cutter diam. of 25 mm
uu
long and slim arbor combinations
uu
minimal vibrations because of special
dense antivibration material
uu
thread connection, no shrinking process
necessary
uu
machining in deep cavities also with ver-
tical walls
uu
for narrow and deep moulds and dies
uu
machining applications with normal vib-
ration tendency
uu
for cutter diam. of up to 42 mm
uu
by directly shrinking the solid carbide
end mill or dense antivibration adaptor in
the arbor taper, you can machine vertical
walls right up to the arbor collar. This me-
ans great increase in rigidity because of
the reduced distance between the spindle
and tool.
uu
machining of extremely deep cavities with
vertical walls in very limited space and
with limited movement of Z-axis, and high
requirements for rigidity and vibration-
free milling
uu
universal and good value solution, direct
grip of solid carbide end mills via collet
without a shrinking device
uu
also grips unusual shank diameters and
shank diameters smaller than 3 mm
uu
for fast changing applications
uu
for finishing, pre-finishing, and moderate
roughing operations
Arbor System Advantages
Recommended Applications
Please note: Zero-reach arbors cannot be ordered separately. We only supply them in a shrink-grip connection with a so-
lid carbide or dense antivibration adapter. (Please indicate desired adapter on purchase order form.)
