So that wasnt a good way.Adding to the challenge was the coolant foaming that occurred, es-pecially when PTT performed high-speed machining at spindle speeds up to 80,000 rpm. He explained that excessive foam can shut down a machine or deplete it of coolant by causing a leak.Starting nearly seven years ago, PTT engineered an operation that uses a state-of-the-art control sys-temwithmotor-commanded pumps and flow meters, Goerges said. The system consists of a cen-tralized pumping station, a con-troller, distribution manifolds and a sensor that drops into a machine tool sump to monitor the coolant level and temperature. PTTs in-house system is connected to 14 machines. However, the modular system is scalable up to 120 ma-chines and can deliver as much as 21,804 L (5,760 gal.) of coolant a day.He ran the initial beta unit forPrecision Tool TechnologiesThe system consists of a centralized pumping station, a controller, distribution manifolds 4.5 years to vet the process.
