The Rebel Ecofeed short bar loader from Edge Technologies is a compact short bar loader that features a 5-mm to 65-mm diameter capacity range for feeding spindle length round, square, hexagonal and shaped barstock into CNC lathes. The bar loader combines the advantages of auto bar loading with a small footprint with a large magazine capacity allowing for long untended operation. High-speed machining is possible with the use of a properly sized lathe spindle liner since there is no contact between the barstock and the loading magazine while processing the bar.
The loading storage capacity is 650-mm (25.6”) deep. Bars are loaded from the rear of the bar feeder. The inclination of the storage table can be adjusted to give the loader a “soft-load“ effect. The bars are then raised gently into the feeding channel by urethane guides, eliminating the potential for marring of the surface of the bars. The machine can be loaded with barstock lengths to as high as 1,500 mm (60“). The maximum bar length is determined by the spindle length of the lathe and the chucking package. The barstock is loaded into the main spindle of the lathe by a linear feed mechanism with an air cylinder. This allows for the feeding of the barstock into position with the use of a fixed bar stop. A quick and accurate adjustment mechanism sets the correct height for the lathe’s centerline, according to the bar’s diameter, for accurate loading into the spindle liner. The machine comes equipped with three pusher rods to cover the range of diameters.
