7 Ways Today’s Bar Feeders Help You Work Smarter

Early attempts at feeding bar stock into turning machines involved simple holding or guiding devices that transmitted vibrations, required slower RPMs, could damage spindles and work pieces, and presented a danger to machine operators.

In the 1970’s, LNS addressed these and other bar loading shortcomings by developing the first hydraulic bar feeders that reduced friction, noise and vibration. In the years since, bar feeding has evolved into user-friendly, ergonomic and highly efficient devices that provide a number of significant advantages. Here are just a few:

  1. Precise bar loading. All LNS automatic bar feeders are designed to continuously feed bar stock without interruption. Many models include a patented, direct headstock synchronization system that ensures coordination of the bar feeder pusher and turning machine headstock. Bar feeders especially designed for very small diameter stock use a unique, scroll-type loading system.

 

  1. Fast changeovers. To keep production moving, LNS automatic bar feeders include features that reduce changeover times to a matter of a few minutes. Models designed for lights-out operation include automatic adjustment capabilities that require no operator intervention.

 

  1. Optimum turning machine RPMs. Proper bar support reduces vibrations to enable higher spindle speeds and maintain tight tolerances. LNS achieves this with rigid, heavy-duty construction and, depending on the model, such features as automatic, self-adjusting outboard bar supports, Swiss Safety Connections and more.

 

  1. Unattended operation. There’s no better way to reduce cost-per-part and meet tight deadlines than by setting up long part runs that require no operator attention. Achieving unattended and lights-out production requires bar feeders that provide automatic changeovers, hold large amounts of bar stock and are proven to reliably load bars for long periods of time.

 

  1. Reduced material costs. LNS bar feeders equipped with a Part Library function that stores up to 500 parts programs, monitor material usage and communicate with the turning machine control. After each part is machined, the lathe’s production scheduling program checks the remaining parts to be produced and determines if there is adequate bar stock available for the next scheduled part to be made. If not, rather than discarding the remnant, the system scans the production list for another part that could be made from the remaining material, and the bar feeder automatically adjusts itself to the new program.

 

  1. Remote monitoring. The LNS e-Connect communications system that enables the bar feeder to share data with the turning machine, can also send a variety of email alerts regarding production status and work cell health to computers, smart phones, and other devices during unattended operation.

 

  1. Easy programming. A user-friendly, prompting, touch screen control makes setups quick and easy. The operator simply enters the bar stock shape, diameter, part length and guiding channel ID.
