HIGH-PERFORMANCE LOADING MAGAZINE ecoPROFI Material diameter: 5 to 45 mm Material lengths: 3,000/4,000/6,000 mm Other lengths on request 6 different guiding channels with high-speed automatic channel switching Production basis for rational, order-based and economical turning with changing lot sizes PERFORMANCE PROFILE Fully automatic loading of long bars directly into the chuck through the lathe spindle. Thanks to the closed guiding channel (oil circulation) and use of suitable spindle filler tubes, the ecoPROFI technology guarantees precise turning at high speeds. The oil circulation creates a hydrodynamic padding, which stabilises the concentricity of the bars and compensates for intermediate material diameters. The workpiece bars are centred automatically under low friction and free of vibrations, thereby removing the load on the lathe spindle in particular. SPACE-SAVING LOADING TECHNOLOGY The bar is fed into the lathe in two steps. The bar is first pushed into the spindle filler tube of the lathe by a driver. A pusher, matched to the guiding channel, then takes over further transport of the bars in the lathe. The workpieces can be positioned alternatively against a limit stop on the turret or by the pusher itself. When the chuck is opened, the bar is moved on without delay and under control. HIGH-SPEED BAR CHANGES The remnants of the bars are ejected into the chip compartment through the spindle (remnant retraction to the rear optional). During machining of a workpiece the separator of the loading magazine already places the next bar from the roller magazine in the guiding channel. The short pusher feeds the bar into wait position. QUICK SWITCHING OF GUIDING CHANNELS The guiding channels are formed by two slot-free aluminium half-shell profiles mounted on rolls lying on top of each other. This technique allows switching from one channel to the next within seconds without manual intervention. Since the guiding channels are divided into several segments, they can be opened individually at the end of the bar for bar feeding (driver/pusher rod). QUICK CHANGE OF SPINDLE FILLER TUBES Breuning supplies individually manufactured spindle filler tubes for every type of lathe. To achieve optimum turning results, the spindle filler tubes and guiding channels must be matched to each other. To change the spindle filler tube, the upper part of the PROFImat loading magazine is swung to the side.

TYPE VERSIONS The size of the PROFImat loading magazine depends on the maximum collet diameter of the lathe that is to be loaded automatically. (Intermediate sizes are possible) For workpiece diameters to 20 mm
TECHNICAL DETAILSDrive and control system: The feed force (torque) and feed speed (motor speed) can be adjusted independently of each other with a specially designed servo drive. The positioning device guarantees safe positioning of the front end of the bar in the work room of the lathe. Breuning has a pool of tried-and-tested interfaces for quick connection to the machines of well-known lathe manufacturers. This reduces the work required for installation and set-up. Options: - Bundle loader - Electromechanical swing device - Axial linear movement - Suitable systems are available to meet special demands on positioning accuracy Captions The guiding channels are formed by two half-shells. Diameter changes are made in seconds without manual intervention Safe reloading of bars with the cover closed
