CNC short drill chuck

Design: Short design, guide elements of rigid design, hardened and ground wear parts ensure high concentricity and long life. Compact design and high rigidity lead to the best machining results. High clam- ping 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.

CNC precision short drill chuck for clockwise and counterclockwise rotation

Design: JISB 6339 (MAS-BT), form AD/B, from alloy case-hardened steel, with a core tensile strength of approx. 950 N/mm 2 and a hard- ness depth of min. 0.5 mm. Taper to DIN 254. Hardened 58 ±2 HRC. Short design with central coolant supply, 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. Taper surface roughness: Ra < 0.001 mm. Concentricity: 0.02 mm. Balancing quality: G6.3 25000 min -1 . Application: For mounting tools with cylindrical shank with internal cooling. Supplied: CNC short drill chuck with sealing disc for coolant drill bits with 3-6 mm dia.
