The new BOSS 547 automatic bar feeder has flexibility and reliability. It runs 2" diameter stock. Compatible with all CNC fixed headstock lathes and automatics, it has a bar capacity of 5 to 51 mm. Magazine capacity is 28 10 mm diameter bars. It is equipped with a quick-change elastic guide channel, permitting the rotation of round, square and hex shaped bars at increased rpm with minimal noise and no vibration. Setup time between bars of different diameter, without guide channel changes, is less than 10 minutes. If channel changes are necessary, setup can be done in less than 30 minutes. A double pusher system reduces the overall length of the feeder, regardless of the machine tool spindle. An oil-lubricated Vulkollan front guide bushing automatically opens to allow the bar pusher to pass through, said to reduce stock vibration at the spindle and provide excellent part finishes and tolerance holding capabilities. In many cases, the Vulkollan front guide bushing allows for a greater size range of bar diameters to be machined without a guide channel changeover. The bar feeder cycle and lathe interface are entirely controlled by a flexible CNC with integrated PLC. All operations are monitored in detail, and a display identifies any process deviations before they become problems. Functions now routinely checked that previously required additional devices include: thrusting clutch adjustment during bar feeder cycle; continuous adjustment of feeding speed; checking feeding length; position on lathe fixed stop without any stroke; easy automatic loading of any shaped bar; rear extraction or front ejection of bar remnant; and electrical interface with all lathe models. The new hand-held digital push-button pendant permits remote control programming, allowing main operations to be done away from the bar feeder at the lathe.
