turbo 3-36 / SFB-310 eco
The bar feeder with integrated high pressure unit.
A process-reliable and stable material feed, combined with the efficient cooling of the tools and the precise removal of produced chips form the basis for an optimal use of the lathe.
The FMB turbo 3-36 HD / SFB-310 eco combines these requirements in particularly user-friendly and space-saving form. The connection of the proven FMB bar feeder technology with the innovative and energy efficient high pressure technology of SF-Systeme BÜCHELE in a compact unit set new standards for usability and handling.
Area of application:
Sliding or fixed headstock lathes with up to 38 mm nominal throughput gap, which process small and medium-sized diameter ranges.
Characteristics
Fast and easy replacement of the inserts makes the efficient adaption of the guide channel to different material diameters possible - inserts, pushers and collets can be put in the integrated storage options.
Optimal accessibility for cleaning and service activities of the high pressure unit thanks to removable tank- and pump module.
Available installation situations
Simple and convenient - the ERGOlogic control ...
Portable control panel
Modern touch control with a large 8.4" screen allows an intuitive operating concept for a short training period. The adjustments of the bar feeder and the high pressure unit can be made centrally through the portable control panel.
Integrated storage option for interchangable parts like inserts, pusher and collets.
Efficient, practical handling ...
Installation position
The optional shifting device makes it possible to move the loading magazine up to 400 mm away from the lathe. This practical feature increases accessibility to the lathe for service technicians, e.g. when replacing spindle liners, or, when switching variable lathes from short-turning to long-turning mode, ensures the shortest distance between loading magazine and spindle stock at all times.
Efficient, practical handling...
Guide channel inserts
The guide channel inserts are quick easy to replace so that the channel diameter can be adapted to the optimum diameter range of the material bars to be processed.
Stable design...
Machine support
The torsion-resistant machine support of extruded aluminium forms the solid basis for the loading magazine. It also holds the diameter-related inserts for the guide channel.
Stable design...
Material bar grippers
The stable gripper design guarantees secure drawing in of the material bar and removal of the remnant piece.
Spindle liners
Spindle liners
On request FMB can also supply spindle liners to match a substantial number of lathe types; these enable the spindle opening to be optimally adapted to match the guide channel diameter.
Optimum material bar guidance...
Steady
The steady at the end of the guide channel takes the form of a flexible roller steady for the processing of round material bars. When processing round, square and hexagonal section materials the guide rollers can be replaced by appropriate material guides (guide jaws). This enables the steady to be set to the dimensions of the material bar, thus guaranteeing optimum guidance even of small-diameter bars in a larger guide channel.
Optimum material bar guidance ...
Synchronizing device
When using a moving spindle stock (e.g. in sliding headstock mode), the synchronizing device uses a coupling system to couple the bar feed device of the loading magazine mechanically to the spindle stock, thus ensuring synchronisation with the movement of the pusher. As an option, the position during this movement can also be monitored by a sensor to prevent any possible collisions, e.g. when switching from fixed headstock to sliding headstock mode.
Optimum material bar guidance ...
Telescopic tube
Telescopic tubes are used to bridge the gap when fitting a bar loading magazine to a lathe with a sliding spindle stock. FMB offers an optional package to suit each type of lathe, to ensure secure protection of the rotating bar and the best possible guidance.
Optimum material bar guidance ...
Spindle stock steady
In addition to the use of a telescopic tube, FMB offers a moving steady for lathes with large travel distances along the Z axis and long spindles. This is linked to the spindle stock, thus offering an additional support point for the material bar in order to reduce the free length between the steady and the collet in the lathe. It reduces vibrations in the material bar and has a positive effect on the production quality of the parts.
