CNC short drill chuck for clockwise and anti-clockwise rotation

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 -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.

CNC short drill chuck AKL 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. 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. ULTRA design (concentricity ≤ 0.015 mm) available upon request.

CNC precision chuck 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.
