The FMB Micromag 20 is an automatic bar loading magazine designed for feeding round, square and hexagonal bar material into CNC lathes. Available from Edge Technologies, a division of Hydromat, it features a 24-bar capacity walking beam system for consistent loading of 0.8 to 3.0 mm barstock, suitable for industries such as medical and electronics. The mechanism folds down when loading larger barstock in the traditional linear feed tray, and an additional storage tray is located on the front of the magazine for fast reloading.
The magazine’s quick-change polyurethane guide channels allow for quiet operation at high rpm. The rotation of the bar creates a hydro-dynamic effect, centering the barstock in the channel reducing noise and vibration. The guide channel is securely closed with a toggle lever system while machining bars. Guide channels are used when loading barstock ranging from 3 to 20 mm.
This model is equipped with a headstock synchronization device allowing rapid backward/forward movements on sliding headstock lathes without forward feed pressure from the bar pusher. A bushing block steady rest device on the turbo guides the barstock between the bar feeder and lathe.
The storage magazine at the side of the guide channel features a loading capacity of 7 linear inches. The new bar is automatically positioned in the lathe ready for facing before the first component is produced. Maximum adjustable feeding speed is 600 mm per second and maximum adjustable return speed is 1,000 mm per second.
