Automatic Bar Feeder For Fixed Or Moving Headstock

Given the designation “One,” this single-spindle line of automatic bar feeders is designed for CNC lathes with fixed or moving headstock. According to the company, the bar feeder is suitable for touch applications such as running hex barstock at a high spindle speed. It includes a hydrodynamic bar guide system with a spring bushing device inside the lathe’s spindle.

Given the designation “One,” this single-spindle line of automatic bar feeders is designed for CNC lathes with fixed or moving headstock. According to the company, the bar feeder is suitable for touch applications such as running hex barstock at a high spindle speed. It includes a hydrodynamic bar guide system with a spring bushing device inside the lathe’s spindle. The bar feeder eliminates the need for the lathe’s stock stop because the new design allows for control of the feed-out within 0.2 mm of accuracy, the company says. The bar feeder’s design synchronizes the bar pusher with the lathe’s moving headstock without mechanical links. The system uses two encoders that communicate with each other, thus eliminating the response delay said to be typical of mechanical devices subject to the inertia of the bar pusher on the moving headstock. The bar feeder is available in a magazine-rack configuration for barstock as long as 13' with diameters between 0.25" to 2.0".
