Imagine you got bar stock from your suppliers that came at random lengths. Or you have materials left over or didn’t use a full bar, and you want to use that in the future. Maybe you want to make the most of your remnants. How does the bar feeder load random length...

Since 2025, we’ve seen an increase in shaft work – more shops making longer parts. 2nd End of Bar (also referred to as EOB protocol or end-of-bar programming) is an advanced bar feeder customization that eliminates oversized remnants by automatically switching to a...

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...

To optimize CNC lathe RPM in bar-fed applications, bar stock should not exceed 0.007" TIR (Total Indicator Runout — the total deviation measured as the bar rotates, indicating how straight or bent it is) per foot, measured at three equidistant points over the full bar...

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,...

RS Technology is a patented redesign of how a bar feeder connects to a Swiss-type lathe. Traditional bar feeders use a telescopic nose — a collapsible tube that bridges the gap between the feeder and the lathe spindle. As Swiss lathes have evolved with longer Z-axis...

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. And, many times, this isn’t a job for just anybody. It has to be scheduled with maintenance, which might spell...

Here’s everything you need to know about automatic magazine bar feeder compatibility and integration. Compatibility refers to whether the bar feeder is well-suited to the specific requirements and constraints of your CNC lathe. Integration involves incorporating a bar feeder into your manufacturing environment.
