The GT 112-E automatic magazine bar feeder from LNS is for sliding headstock machines running unattended or lights-out production, using small bar stock with diameters from 0.8mm to 11mm.

A dual U-shaped guiding channel with a patented sectional guiding channel cover, combined with a self-centering bar clamping system, matches the entire diameter range of the lathe. The single pitch screw magazine keeps small bars separated for consistent and reliable bar loading.

Two GT 112-E versions are available, one for 12’-2” bars and another for 6’-6” bars. Both units have compact designs that take up less floor space.

Setup takes two minutes or less by inputting bar diameter, feed out length, and guiding element diameter into the prompting, handheld, touch screen remote control (HMI). The bar feeder then automatically sets pushing torque, forward speed, and feeding length.

Other features include:

  • Electro-mechanical headstock synchronization of bar stock
  • LNS safety joint pipe spindle reduction system that contains the bar and eliminates the need for spindle liners
  • Magazine tray holds up to 30 bars with 7mm diameter and under, and 15 bars over 7mm
  • Optional 400mm Z-axis bar feeder retraction system allows easy maintenance access
