Bar loading magazine with hydrodynamic (oil-flushed) bar guidance

Developed and patented by FMB: the turbo principle by which the guide channel is supplied with oil.

Bar loading magazines with hydrodynamic bar guidance have long been a part of the FMB range.  They are used in all cases where the material bars to be fed are longer than the spindle length of the lathe. In these cases, in addition to the staged feed of the material bars, the loading magazine also needs to guide the rotating bars outside the lathe. The optimum guidance of the bars is achieved by a technique that has been developed and patented by FMB, known as the turbo principle. The guide channel is filled with oil, under a slight pressure of 1-2 bar. This achieves a low-vibration bar guidance even at high rotation speeds, and centres the bars within the guide channel. This technique is generally suitable for bars with round, hexagonal or quadratic outer contours, which may have either hollow or solid cross-sections.

Over recent years, FMB has further perfected this principle and now offers magazines in a variety of lengths for bar diameters in a range between 0.8 and 100 mm. The bar materials for processing are steels, aluminium, brass and thermoplastics or thermosetting plastics.

This technique is intended for use with single-spindle lathes, whether with fixed or sliding headstock. These FMB bar loading magazines are especially suited to the automation of lathes that can support either process.
