Design: DIN 69893, Form A.
Short design, guide elements of rigid
design, hardened and ground wear parts ensure high concentricity and
long life. 100 % concentricity test with different plug gauge diameters
at various measuring points, based on DIN ISO 10888. Compact
design and high rigidity result in best machining results.
High clamping forces are reached by the integrated worm gear at low
effort,
Holding torque > 75 Nm at 13 mm diameter.
Machining
is safe thanks to automatic blocking of the worm gear even when
running anti-clockwise and quickly decelerated spindle.
Taper angle: Tolerance AT3.
Taper surface roughness: Ra < 0.001 mm.
Balancing quality: pre-balanced up to 7000 min
-1
at a residual
imbalance of max. 40 gmm.
Concentricity: < 0.03 mm.
Max. permissible speed: 7000 min
-1
.
Application:
For drilling, countersinking, reaming, thread cutting and
for simple finishing milling work. Can be used in machining centres,
turning, drilling and milling machines.
Scope of delivery:
Short drill chuck with hex spanner.
Note:
Higher speeds possible with special balancing. Also available as
ULTRA design (concentricity ≤ 0.015 mm).

CNC short drill chuck AKL for clockwise and anti-clockwise rotation
Design: DIN 69893, Form A,
made of special case-hardened
steel for highly stressed components, with a core tensile strength
of min. 1000 N/mm
2
. Chuck and shank in one piece. Clamping
(using a hex spanner) essentially increases clamping force in
comparison to conventional chucks. At the same time, this secures
the chuck against becoming loose during left-handed rotation or
being quickly decelerated from higher speeds.
Taper angle: Tolerance AT3.
Balancing quality: G6.3 25000 min
-1
.
Concentricity: 0.02 mm.
Hardened 58 ±2 HRC.
Application:
To nest tools with cylindrical shank.
Scope of delivery:
CNC precision drill chuck with hex spanner
including sealing disc for coolant drill bits with 3-6 mm ∅.
