Edge Technologies Bar Feeder Provides Optimal Stock Support

Edge Technologies has introduced the FMB Turbo RS 4-45 bar feeder for Swiss sliding-headstock lathes with diameter capacities up to 42mm.

The Turbo RS 4-45 required FMB to develop its largest extruded machine base yet. This rigid foundation is the key starting point for a feeder that features RS (revolutionary sliding) technology as standard. According to the company, the RS design enables Swiss lathe users to improve performance, especially for lathes with longer Z-axis strokes, demanding applications such as non-guide bushing mode, challenging materials and profiled stock. The integrated and oiled sliding guide module and moving steady rest provide optimal bar pusher and stock support in the transition zone between the bar feeder and lathe spindle. FMB’s RS technology eliminates the need for telescopic noses, extended pushers and Z-axis axial tracks, all of which minimize the gap between the bar feeder and lathe. The result is reduced vibration, a significant boost to maximum rpm, better surface finishes and an ability to hold tighter tolerances.

The Turbo RS 4-45 is available with an Auto Adjust capability. Auto Adjust magazine bar feeders are well suited for optimizing CNC turning centers that specialize in short-run work with frequent changeovers over a wide diameter range. The Auto Adjust matches the maximum-sized bar pusher to the CNC lathe draw tube or the maximum-sized stock. The bar feeder does the rest with a series of aperture-like geared mechanisms that automatically adjust to and support the rotating stock. Users need only to change two parameters in the controller and change the bar pusher collet to be ready to run a different diameter.
