Minimag 20 Bar Feeder

The FMB Minimag 20 is an automatic Bar Loading Magazine Feeder for processing bars in the diameter range of 2-20 mm in lengths from 6’ to 14’ on CNC lathes.

Equipped with a Swiss-type headstock synchronization device, peck drilling and threading on small diameter bars is simple and done with high-tolerances.

To increase the productivity on your Swiss type lathe, the Minimag 20 is a smart choice.
