Bar Feeder for High-Speed, Small-Stock Production
April 1, 2014
Lexair's Mini Rhinobar bar feeder is designed to automatically center and feed small diameter bar stock to maximize the productivity of Swiss-style CNC screw machines and small fixed or sliding head lathes.
The precision engineered single tube bar feeder uses the hydrodynamic principle to quickly center 6" (1.8 m) or 12" (3.6 m) bars as small as 0.04" (1 mm) diameter. The bar stock is supported in an oil bath in the feed tube; as the bar's rotational speed increases, hydrodynamic forces move it toward the center of the tube and stabilize it. According to the company, this provides shorter cycle times and enhanced workpiece finishes. Feed tubes ranging from 0.125" to 1.625" (3.2 to 41 mm) diameter are available in 0.125" (3.2 mm) increments to help minimize the bar to feed tube clearance and achieve enhanced throughput on automotive components, medical devices, motor shafts and other small diameter, high-production run parts.
The bar feeder's ergonomic design features an upgraded safety interlock system and includes a front swing out mechanism for easy reloading and sub three minute feed tube changes. Lexair's single valve design controls oil flow and pressure for increased bar control, accuracy and vibration-free operation. A completely enclosed fluid recuperator keeps oil off the floor and contaminants out of the hydraulic system.
The outer barrel is a precision extruded aluminum tube held in place with a single clamp to further minimize barrel vibration and control Z-axis motion. A removable pendant allows the operator to control the bar feeder remotely, while a positive pusher retention system is intended to provide high efficiency operation with minimal labor.
With overall machine lengths of 11' (3.35 m) for the 6' bar model and 17' (5.18 m) for the 12' bar model, the Mini Rhinobar's compact size makes it suitable for small or large shops. The U.S.-built bar feeder is available for immediate delivery, and comes with three feed tube diameters of the buyer's selection.
