  • Page 17: Bar Feeder General Description

    2 - TECHNICAL INFORMATION BOSS 552-IC BAR FEEDER GENERAL DESCRIPTION The BOSS automatic bar feeder is used in the machine-tool industry and in particular, for automatic lathe feeding. It is particularly suitable for feeding fixed or sliding headstock lathes, numerical control or cam lathes. The operating cycle is controlled by a PLC, integrated in the electrical control panel, which is able to communicate with the lathe control system.
  • Page 18 2 - TECHNICAL INFORMATION BOSS 552-IC • MAIN PARTS A MAGAZINE; it stores the bars. B BAR SELECTION DEVICE; it enables the first bar to be lowered into the guide channels and holds the remaining bars in the magazine. C GUIDE CHANNELS; they guide the bars during machining.

  • Page 19: Operating Cycle

    2 - TECHNICAL INFORMATION BOSS 552-IC OPERATING CYCLE In the automatic operation mode, bar feeder movements are controlled in the sequence described below. The bar pusher "A" feeds bar "B" in the lathe, by following lathe pulses, until bar end. The bar pusher A and remnant C are in their forwards limit stop position.
  • Page 20 2 - TECHNICAL INFORMATION BOSS 552-IC Clamps "D" close again to check remnant "C" removal. If the remnant is still inserted in the bar pusher collet, the bar feeder stops; otherwise, it continues its cycle. Upper guide channels "H" open together with bar pusher "A";...
