turbo 5-65

Magazine for bar diameters of 5–65 mm.

The FMB turbo 5-65 is a magazine for bar diameters from 5–65 mm which, like the smaller model variants, works on the principle of two-stage feed that characterises the turbo series. The swivelling pusher means that a very compact, space-saving construction can be achieved. The solid machine bed of grey cast iron also ensures the necessary stability, especially for the precise machining of larger material bar diameters.

Area of application:

Single-spindle lathes with up to 65 mm nominal throughput gap, intended for the permanent processing of medium-sized to large diameter ranges or the occasional processing of small bar diameters.

Where lathes are used for material bars with frequently differing diameters, the turbo 5-65 V variant model provides an optimum solution for further production efficiency increases.

The V variant has moveable guiding segments that are automatically set to the required material bar diameter, thus preventing the need for refitting the guide channel inserts or changing the pusher over wide ranges. The proven benefits of the hydrodynamic bearing effect of the oil-flushed channel are not affected. After inputting the material bar diameter on the control panel, the guiding segments in the channel set themselves and the stops of the material bar separation system are automatically moved to the required position.

Production processes that place high requirements on the insertion position without the use of a mechanical stop can be given optimum support by using the turbo 5-65 XT variant model. The use of a precision linear drive on the feed axle means that the XT variants are more accurately positioned yet can feed the bars very dynamically. In certain cases this can lead to production efficiency increases.

Features

  • Short design based on a two-stage feed principle (swivelling pusher)
  • Fast, simple changing of the inserts for efficient adaptation of the guide channel to different material diameters
  • Highest possible guide quality and vibration damping by the use of polyurethane inserts, combined with a solid machine bed of grey cast iron.
  • Optional V variant with automatic diameter adjustment of the guiding segments in the channel and material bar separation by means of inputs on the control panel.
  • Optional XT variant with precision linear drive enables bars to be fed without the need for a stop, with great accuracy and high feed speeds

Available installation situations

Ergonomische und einfache Bedienung…

Ergonomic and simple operation...

Mobile control panel

Easy handling of the FMB loading magazine is supported by a detachable user-friendly control panel. It can be combined with a high-performance programmable logic control (PLC) system to enable FMB to produce very flexible customer-specific special functions and processes.

Effiziente und praxisorientierte Handhabung…

Efficient, practical handling...

Bar loading

The wide material storage facility offers space for 3 to 48 bars, depending on diameter, in order to allow the lathe to operate for a maximum length of machining time without interruption. The inclination angle of the material storage facility can be infinitely adjusted so that it always guarantees the best possible feed of all kinds of material and profile.

Effiziente und praxisorientierte Handhabung…

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 polyurethane guide channel inserts with sound damping properties are quick and easy to replace, so that the channel diameter can be adapted to the optimum diameter range of the material bars to be processed.

Adjustable guide channel (V variant)

The moveable guiding segments are automatically set to the required material bar diameter. This prevents the need for changing the guide channel inserts and the pusher over a wide range of diameters*.

* When processing diameters < 20 mm, it is recommended that the adjustment of the guide channel diameter is checked by FMB

Effiziente und praxisorientierte Handhabung…

Efficient, practical handling...

Automatically adjustable material separation (V variants)

The stops for the material bar separation on the lateral material storage facility automatically move to the preset material bar diameter.

Precision drive for material feed (XT variants)

A precision linear drive enables bars to be fed without the need for a stop, with high top speeds.

This leads to:

  • Time savings and high productivity
  • Protection of the machine tool
  • Additional space for tools because there is no stop
  • Low feed tolerances and quiet running

Machine support

The solid, torsion-resistant machine bed of grey cast iron forms the solid basis for the loading magazine. This guarantees the highest possible guide quality and vibration damping.

Material bar grippers

The stable gripper design guarantees secure drawing in of the material bar and removal of the remnant piece.

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.

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.

Synchronizing device (not on XT and V variants)

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.

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.

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.

VST hold-down function (not on XT and V variants)

This option is suitable for lathes with a fixed spindle stock. It prevents the pusher from tipping during follow-up and when the collet is open. The pusher is fixed from above in the front area of the channel with 2 pneumatically operated prisms, and prevents the material bar from being clamped off-centre in the chuck. The pusher is also stabilised during the turning process. This method has a positive effect on the quality of the parts produced.
