Condition: used, Year of construction: 2005, functionality: fully functional, RAKO 12-Jaw Precision Clamping System Ø 1,600 mm with Extensive Jaw Set (2 units in stock) Manufacturer: RAKO GmbH, Gelenau Manufacturer's designation: 12-Jaw Chuck Year of manufacture: 2005 Documentation date: 2006 Drawing number: 0684.00-00 Article number: MPT-1023 / 1024 Offered is a used, stationary RAKO 12-jaw precision clamping system for mounting on a fixed machine table. The clamping system was used for machining brass cages for ball and roller bearings. It is not a conventional turning chuck for a machine spindle, but rather a permanently mounted workpiece clamping device. The design features twelve basic jaws arranged radially and evenly around the circumference. This distributes the clamping force over numerous contact points. This clamping principle is particularly suitable for large, ring-shaped, thin-walled, sensitive, or easily deformable workpieces. According to the existing manufacturer's drawings, different jaw positions are possible for internal and external clamping. The clamping system has an outer diameter of approximately 1,600 mm and a weight of approximately 2,000 kg. Scope of delivery - RAKO 12-jaw clamping system, Ø approx. 1,600 mm - twelve radially arranged basic jaws - extensive set of various clamping and adapter jaws - different interchangeable and clamping elements - additional fastening and accessory parts as shown in the images - separate wooden crate with jaws and accessories - original RAKO operating manual - overall, section, and detail drawings Prjdezx D A Depfx Aazjb - drawings of various clamping positions The exact quantity and assignment of all jaws and accessories have not been finally determined. The scope of delivery is based on the images. Condition Used condition with signs of wear and tear due to age and use. Scratches, dirt, discoloration, and, in some places, slight surface rust or corrosion can be seen on the clamping system and individual accessories. Technical data - Outer diameter: approx. 1,600 mm - Weight: approx. 2,000 kg - Number of basic jaws: twelve - Jaw arrangement: radial and even - Clamping options: internal and external clamping - Jaw stroke: 28 mm according to drawing - Total clamping force: approx. 190 daN at 35 Nm actuating torque - Maximum torque on the actuating spindle: 100 Nm - Locking air: present - Maximum locking air pressure: 5 bar - Lubrication: on the twelve basic jaws and the actuating spindle - Transport: three threaded holes M30 for crane screws Mounting on the machine table According to the RAKO operating manual, mounting is done with 14 cylinder head screws M20 × 180 according to DIN 912, strength class 10.9. The specified tightening torque is 300 Nm. Jaws and accessories The scope of delivery includes an extensive range of different clamping and adapter jaws. Documented, among other things, is an adapter jaw H41 with drawing number 0721.02-03 and a finished size of 55 × 50 × 46 mm.
