What is an Automatic Bar Feeder?
An automatic bar feeder is a material handling system that feeds bar stock into a CNC lathe or turn-mill center for continuous, unattended production of turned parts. The bar feeder holds multiple bars in a magazine, automatically advances new stock when the previous bar is consumed, and ejects remnants. For titanium fastener manufacturing, bar feeders are essential for achieving production targets — enabling 'lights-out' operation on CNC lathes with automatic bar feeding through 2nd and 3rd shifts.
