Edge Technologies offers the FMB 20-100 bar feeder, an addition to its Turbo “Heavy Metal” line of hydrodynamic 12- to 24-ft. bar-loading magazine feeders. The feeder is compatible with all types of sliding or fixed, CNC- or CAM-operated lathes with spindle bores as large as 102 mm.
A one-size channel set automatically adjusts for all material sizes, and quick-change polyurethane guide channels support quiet operation at high speeds while feeding round, square or hex barstock. The polyurethane, oil-filled guide channels envelop the stock, and can be changed in about 10 min. to accommodate multiple barstock diameters, providing the optimal guiding system for high-rpm turning operations, the company says. During operation, the rotation of the bar creates a hydrodynamic effect, centering the barstock in the channel, reducing noise and vibration.
Bars are placed in the storage magazine at the side of the guide channel, which offers a loading capacity of 11". The new bar is automatically positioned in the lathe, ready-for-facing, before the first component is produced. According to the company, maximum adjustable feeding speed is 700 mm per sec. and maximum adjustable return speed is 1,000 mm per sec. A roller steady device guides the barstock between the bar feeder and lathe. Rollers or blocks provide consistent feeding of round or profiled material, and the rollers can be quickly adjusted to the bar diameter. The bar feeder's cast iron base and support stands resist flexing and vibration, and its double-pusher space-saving design is 4 ft. shorter than single-pusher bar feeders.
The bar feeder features a Bosch IndraDrive controller with a servomotor drive to the feed mechanism. According to the company, options on the operator control panel ensure proper interaction between the bar feeder and the CNC lathe, with parameters clearly shown on the text display.
