LNS’ GT 112-E automatic magazine bar feeder is for sliding headstock machines running unattended or lights-out production using small barstock with diameters from 0.8 mm to 11 mm (12.7 mm with bar preparation). A dual U-shaped guiding channel with a sectional guiding channel cover, combined with a self-centering bar clamping system matches the entire diameter range of the lathe, the company says. The single pitch screw magazine keeps small bars separated for bar loading.

Two GT 112-E versions are available, one for 12’-2” bars and another for 6’-6” bars. According to the company, 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, touchscreen remote control (HMI). The bar feeder then automatically sets pushing torque, forward speed and feeding length.

Other features include electro-mechanical headstock synchronization of barstock; a safety joint pipe spindle reduction system that contains the bar and eliminates the need for spindle liners; a magazine tray that holds up to 30 bars with 7-mm diameter and under, and 15 bars over 7 mm; and an optional 400-mm Z-axis bar-feeder retraction system that allows easy maintenance access.
