CNC short drill chuck AKL for clockwise and counterclockwise rotation

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 dia. Machining is safe thanks to automatic blocking of the worm gear even when in left-handed rotation and quickly decelerated 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. Note: Higher speeds possible with special balancing. Also available as ULTRA design (concentricity ≤ 0.015 mm).

CNC precision drill chuck for clockwise and counterclockwise rotation

Design: DIN 69893, form A, from special case-hardened steel for highly stressed components, with a core tensile strength of min. 1000 N/mm 2 . Hardened 58 ±2 HRC. Short design, 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. Concentricity: 0.02 mm. Balancing quality: G6.3 25000 min -1 . Application: To nest tools with cylindrical shank. Supplied: CNC precision drill chuck with hex spanner incl. sealing disc for coolant drill bits with 3-6 mm dia.
