CNC precision chuck for clockwise and anti-clockwise rotation

Design: DIN 2080, Form A, made of alloy case-hardened steel, with a core tensile strength of approx. 950 N/mm 2 and a hardness depth of min. 0.5 mm. Taper according to DIN 254. Short design, chuck and shank in one piece. Clamping (using a hex spanner) considerably increases clamping force in comparison to conventional chucks. At the same time, this secures the chuck against becoming loose during anti-clockwise rotation or being quickly decelerated from higher speeds. Taper angle: Tolerance AT3. Taper surface roughness: Ra < 0.001 mm. Bore tolerance: H5. Balancing quality: G6.3 7000 min -1 .

CNC short drill chuck AKL for clockwise and anti-clockwise rotation

Design: DIN 2080, 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: G2.5 20000 min -1 Concentricity: < 0.03 mm. 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.
