Short loaders, or spindle-length loaders, can be a very cost-effective solution. They occupy minimal floor space, don't need to be attached to the bar stock, and don't demand bar end preparation. Because the entire bar stock is contained within the lathe headstock,...

In high-speed CNC lathe operations, 12 and 6 ft bar feeders use hydraulic oil to achieve the hydrodynamic effect (sometimes called the hydrostatic effect). The hydrodynamic bearing effect keeps the bar stock spinning smoothly. A thin layer of oil forms a pliable...

A bar feeder should never limit the RPM of a CNC lathe. But, in recent years, on Swiss-type lathes, strokes have gotten longer. As a result, sheet metal gaps have widened, and shops have experienced what they call the Achilles Heel of bar feeders: a jump rope or tail...

Guide channel changeovers can take time. Depending on the bar feeder model and condition, and the expertise of the machinist, they can take up to 30 minutes. You must remove all guide channel sets and slide them out one by one, which can be up to 15 pieces per set....

To optimize CNC lathe RPM in bar fed applications, your bar stock should not have more than 0.007” total indicator runout per foot as measured at three equidistant points over the full bar length. Here's the inspection procedure for bar straightness: Place bar stock...

Deciding on an automatic magazine bar feeder? An automatic bar feeder can be a relatively low investment to eliminate tedious manual operations and empower your machinists to attend to multiple machines at once. Many factors go into deciding a bar feeder. Perhaps the...
