kontur 70
Specially designed for processing profiled material bars.
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.
The FMB kontur 70 is a loading magazine specially designed for processing profiled material bars. The material bars are guided by bushing units on ball bearings. These are fitted with at least 8 replaceable plastic guide bushes, which have locating holes corresponding to the profile of the material bar. It is designed for materials bars with external diameters between 20 and 70 mm, and works on the principle of a two-stage feed.
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 asymmetrical profile types.
Area of application:
Single-spindle lathes up to approx. 70 mm nominal throughput, on which profiles material bars of lengths up to 3,200 mm are continuously machined.
