Cincinnati CNC > Arrow 500 Spindle Lube Fault
Re: Arrow 500 Spindle Lube Fault - where is the lube? The spindle uses a air/lube system that is monitored by a box in the outside of the back of the machine under a cover. It looks at several inputs from pressure switches and has a timed cycle. You should see some lights on this box with faults next to the lights.
