14.5 Stage 4 - Oil distribution
The main coolant pump delivers the oil to a distribution manifold located at the rear of the machine
base which feeds two solenoid operated valves.
The valves direct the oil to the machine base (also called “basewash”) or switched to the grinding
wheelhead via program M-codes when a grinding or dressing cycle is executed on the machine.
M08 grind/dress coolant ON
M09 grind/dress coolant OFF
14.6 Stage 5 - Oil Return
Oil flows from the machine back to the coolant system via oil return chutes and then the oil filtration
and cooling cycle starts all over again from Stage 1.
