LNS North America’s LNS Quick Load Servo 105 automatic bar feeder is designed to precisely load ¹/₄"-4 ¹/₈" (6 mm to 105 mm) diameter, spindle length bars with overall lengths of 11" to 63" (not to exceed the combined length of the headstock, chuck and actuator). Model 105-L (extra-long pusher) loads bars with diameters of _³/₈"-4 ¹/_8" (9.5 mm to 105 mm).

The bar feeder features an advanced touchscreen HMI which the company says enables automatic, partial changeovers in 15 sec. or less, and one minute or less complete changeovers. Additionally, it is said the user-friendly HMI uses QR codes for easy servicing, forecasting tools and a 500-part setup library. The bar feeder’s newly designed main cover also lifts upward for easier access.

It also has a 26" (650 mm) heavy-duty magazine which can stage up to 1,430 lbs of barstock for long unattended and lights-out production runs. It is said the tray is easily adjustable for specific applications and bar shapes can be loaded from the front or rear to conserve floor space. It also has a clear window for viewing remaining material.

An optional Lift magazine enables manual, forklift or crane-assisted heavy bar loading at a lower height, while maintaining full Z- or X-axis retraction function and accessibility.
