Here’s How Fast and Easy you can Set Up & Changeover LNS Bar Feeders by Model

The ability of a bar feeder to improve productivity hinges on three key factors:

  1. consistent, reliable bar loading
  2. proper support that enables optimum turning machine performance
  3. quick, easy setups and changeovers


Every LNS bar feeder is carefully crafted to deliver on all three of these important issues. When it comes to productive setup and changeover times, LNS bar feeders have no equal. Moreover, LNS does not claim unrealistic changeover times by using inflated diameter ranges within guide channels that produces inadequate bar support.

Below is a short explanation, by LNS model, of changeover procedures and times. Complete specifications and product brochures for each model are available in the Products section of this Web site.
