Form
A
Design:
Short design, guide elements of rigid design, hardened and
ground wear parts ensure high concentricity and long life. Compact
design and high rigidity lead to the best machining results. Due to
integrated screw gearing, high clamping forces are achieved with little
effort,
holding torque > 75 Nm at ∅ 13 mm.
Self-locking screw gea-
ring makes processing safe even in reverse and with quickly braked
spindle.
Taper angle: Tolerance AT3.
Taper surface roughness: Ra < 0.001 mm.
Concentricity: < 0.03 mm.
Max. permissible speed: 7000 min
-1
.
Balancing quality: pre-balanced up to 7000 min
-1
at a residual
imbalance of max. 40 gmm.
Application:
For drilling, countersinking, reaming, thread cutting and
for simple finishing milling work. Can be used in machining centres,
turning, drilling and milling machines.
Supplied:
Short drill chuck with hex spanner.
