Expanding mandrels

The various application areas of the cartridge mandrels require a varied programme which ranges from manual or power-operated versions to versions with and without axial tension. The centric and comprehensive internal clamping of cartridge mandrels are particularly impressive for very small clamping diameters and at low overall heights. ADVANTAGES AT A GLANCE - Stable clamping by axial tension against workpiece stop - Low weight and reduced overall height by a compact design - High axial run-out precision, concentricity and repeatability For small clamping diameters and low construction heights: The MZE mandrels from Röhm The clamping and gripping specialist Röhm provides solutions for the greatest variety of machining tasks. When it is necessary to perform light turning, grinding and measuring work, the MZE cartridge mandrels are the first choice. Their strengths come into their own for workpieces with small clamping diameters and low construction heights. In addition to properties that apply to all mandrels, such as the centric and comprehensive internal clamping, the MZE provides in particular high concentricity and repeatability within 0.01 mm. This is achieved thanks to the double-sided, slotted clamping sleeve. The tool-free quick change of the clamping sleeve ensures fast retooling. With a clamping range of 8 to 230 mm, the system is suitable both for workpieces with small as well as large clamping lengths. The low weight and reduced construction height complete the overall package perfectly. The assortment in a wooden box can be used to be equipped for the greatest variety of machining tasks. Different clamping diameters can be machined with it.

- Segment clamping sleeve with innovative vulcanisate for great elongation, longest service life and vibration dampening - Hardened and ground steel segments for high resistance to wear Modern manufacturing technology can hardly do without the use of segment clamping mandrels. In the fields of precision machining, turning, grinding, gear cutting and checking, segment clamping mandrels assume important tasks that are associated with challenging conditions. The innovative rubber segments enable a great elongation of the clamping sleeve to 1.2 mm. ADVANTAGES AT A GLANCE - Short tooling and non-productive times thanks to the great elongation of the clamping sleeve up to 1.2mm - Vibration dampening and long service life thanks to innovative vulcanisate of the clamping sleeves - Fast replacement of the clamping mandrel thanks to the patented bayonet quick change system ABSIS Segment clamping mandrel, power-operated with flanged seat; for internal clamping consists of basic mandrel, adapter, ejector ring, locking belt compact, solid design for precise machining steady clamping by axial draw-in The draw-in of the work-pieces against the rigid work-stop takes place independently via the operation og the mandrels. vibrations damping by the rate of rubber, the segment sleeve is including Technical features high axial- and radial accurancy; high repeating accurancy hardened low-wear construction, hardened (clamping-) segements (grade >60HRC) high accurancy by guiding the sleeves on the clamping mandrel integrated hand-operated lubrication quick change of the clamping sleeves by central draw bolt Customer advantages little height by compact design for automatical charging intermediate flanges and different mandrel sizes are optional combinable adaptable on lathe chucks DURO-NC (employing quick-change systems) wide clamping range per mandrel size
