Six-Foot Bar Feeders Production of longer parts, use of expensive materials and higher volume part runs are among the application criteria that point to 6-foot bar feeder implementation. Depending on a shop's needs, a 6-foot bar feeder may provide the best features of both 12-foot and short load loaders: • L ess material waste with only two remnants per 12-foot bar • L ess space required than a 12-foot bar feeder • F ewer problems with material straightness • Q uick setup Although not as versatile at running profiled material as a short loader, the right 6-foot bar feeder is capable of effectively loading many kinds of shaped material. A 6-foot bar feeder is also a good alternative to a short loader for machines with short spindles. In these applications, it will reduce material waste, increase production capacity and allow easy handling of heavy bars. Connectivity In addition to deciding on the size and type of bar feeder to fit specific applications, it's important to consider how the device will integrate into the overall manufacturing process. is is especially significant as we continue to refine produc- tion through the use of real-time data. Many LNS bar feeders, for example, are equipped with parts libraries capable of storing up to 500 part programs. Using the LNS e-Connect system, which shares data with the machine tool control, the bar feeder automatically detects the part program that the CNC lathe is using and then transmits the correct setup data for that part from the parts library to enable change-overs on the fly, with no operator involvement. In this way, production of a large family of parts or a group of unrelated parts proceeds with little or no intervention by the operator for truly unattended operation. is sharing of data between the bar feeder and CNC lathe can also significantly reduce material costs by enabling the bar feeder to continuously tell the machine tool how much barstock is available for machining. If the CNC machine is equipped with a production-scheduling program, after each part is machined it can check the remaining parts to be produced and determine if enough barstock remains for the next scheduled part to be made. If not, the system checks the CNC machine's production list for another part that can be made from the remaining material. If the parts are prioritized within the list, the system identifies the highest priority part the machine can make from the remaining stock. Fitting a Budget Bar feeders come with a range of features, benefits and price tags. LNS offers affordably priced short bar loaders and bar feeders for 6-foot and 12-foot bar lengths that provide automated machining at the most common spindle speeds and feed rates. On the other end of the spectrum are even :: Electronic synchronization connects directly to the servodrive to eliminate transmission delay and guarantee synchronization between the pusher and the headstock. Choosing an Automatic Bar Feeder productionmachining.com :: 35 :: A user-friendly touchscreen control with prompting menu screens assists the interaction between the bar feeder and the lathe, increasing the safety and efficiency of the production process.
