Design:
Short model, guide elements of rigid design, hardened and
ground wearing parts for a long life span. 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

CNC short drill chuck for clockwise and anti-clockwise rotation
Design: DIN 69871, Form AD.
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.

CNC short drill chuck AKL for clockwise and anti-clockwise rotation
Design: DIN 69871, Form A.
Short design, chuck and shank in one
piece. Taper to DIN 254. 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.
Taper surface roughness: Ra < 0.001 mm.
Balancing quality: G2.5 25000 min
-1
.
Concentricity: 0.02 mm.
Application:
To nest tools with cylindrical shank.
Scope of delivery:
Short drill chuck with hex spanner.
