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, 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...
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,...
