minimag 20

Magazine for bar diameters of 2–23 mm.

It operates on the principle of a single-stage feed. The pusher does not tend to swing inwards, which allows for very economical material bar changeover times and a particularly stable process for drawing out even very thin material bars.

Area of application

Sliding headstock lathes with up to 23 mm nominal throughput gap, which process small diameter ranges permanently or occasionally.

  • Short material bar loading time due to single-stage feed principle
  • Fast, simple changing of the inserts for efficient adaptation of the guide channel to different material diameters

Modern touch control with generously sized 8.4“ screen makes an intuitive operating concept
possible for a faster learning phase. Integrated assistant function for guided set up for inexperienced users.

Available installation situations

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.

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.

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.

Material bar grippers

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

Spindle liner

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 is adjustable and designed with jaws, enabling it to be used for round, square or hexagonal section materials. The steady has easily replaceable (material guides), enabling it 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

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.
