In the world of CNC (Computer Numerical Control) machining, few things are as critical—or as misunderstood—as spindle orientation. Whether you are performing rigid tapping, automatic tool changing (ATC), or using a C-axis indexing feature, the spindle must know exactly where it is in rotational space. For Fanuc-controlled machining centers and lathes, one parameter stands out as the gatekeeper of this function: Fanuc Parameter 1860.

Solution: First, ensure mechanical freedom (check belt, bearings, drawbar). Then increase 1860 gradually. Mastering Fanuc Parameter 1860: The Complete Guide to
Directly editing 1860 is rare and usually unnecessary because the "Zero Return" procedure updates it automatically. However, if you must change parameters: Lock and Test: Solution: First, ensure mechanical freedom
Parameter 1240: Sets the coordinates of the first reference position (G28) in the machine coordinate system.
