Bar loading magazine with ball-bearing mounted bar guidance

For when material bars need to be fed to the lathe in reproducible alignment.

Bar loading magazines with ball-bearing mounted bar guidance are fundamentally different from solutions with hydrodynamic guidance. Whenever profiled material bars need to be fed to the lathe in reproducible alignment, FMB uses ball bearing-mounted bushes as the guiding element. In these cases, too, the material bars can be longer than the spindle length of the lathe, so that in addition to the staged feed of the material bars, the loading magazine also guides the rotating bars outside the lathe. In order to provide optimum guidance even for asymmetrically profiled cross-sections, FMB uses guide bushes with a locating hole that corresponds to the profile of the material bar. This concept includes an alignment device developed and patented by FMB, which inserts the material bars at a precise, repeatable angle into the clamping system of the lathe.

This system is generally suitable for bars with individual, hexagonal or quadratic exterior contours in full cross-section. FMB currently offers the Kontur 70, a magazine for bars up to 3.2 m in length and an external diameter of between 20 and 70 mm. The bar materials used are generally steels, aluminium and brass.

This system has been designed for use with short-turning single spindle lathes. Particularly when processing profiled material bars in a wide variety of forms, lathes can be optimally automated with a bushing-aligned bar loading magazine from FMB.
