Load Meters

Load meters are common on CNC machines to give the operator a reliable piece of feedback data indicating how hard the machine is working.  Because the axes are moved by motors much of the “feel” is lost.  Load meters are simply ampmeters connected to the spindle or axis motor which gives a reading as to how much current is being drawn (and hence how hard they are working).  It is helpful to have a load meter on each axis as well as on the spindle to have the best indication of what is happening.
