Minuteman 320 Bar Feeder

Make: EDGE | Bar Length: 6', 12' | Bar Diameter: 0.118” – 1.062”

The Minuteman 320 SE, available in 6′ or 12′ configurations, is an magazine style automatic bar feeder designed for feeding round, square and hexagonal bar stock in lengths up to 12′, in a diameter range of 3-27 mm, into CNC lathes.

The Minuteman comes equipped with a Mistubishi controller and Servo drive standard. It also features dual anti-vibration devices that stabilize the bar stock at two critical points between the guide channel and lathe spindle maximizing RPM potential. The polyurethane guide channels are reinforced with steel to increase strength and stability.

If you need a quality automatic bar feeder on a limited budget, look no farther than the Minuteman 320 SE.
