Bar feeder-loaders feed or push a bar into a machine, generally a lathe. These are offered in a few different types, including hydraulic single tube, which usually has a 12’ long capacity that surround the bar with oil while it spins to minimize vibration, they have a small diameter range for each bar. However, some manufacturers have Gatling gun style that have several size tubes to cover the range that easily change just by rotating the cylinder, some examples are LNS, and Speco. Some are even offered in Hydraulic magazine which will actually change to the next bar automatically like the Lemca or Cucchi.
Although a bar feeder seems like a relatively simple device, it’s actually the most common automation accessory in the world, as it provides a reliable way of feeding/loading material into CNC lathes/CNC machining centers for extended periods of time.
In reality, these feeders have many differences from one to another which ends up making them more suitable to individual shop needs. A few things to consider when purchasing a feeder/loader are what’s the length and capacity you will need for your environment and/or production needs.
Minimize operator intervention.
Shorter lead times.
Saves an operator from loading blanks into a chuck.
