Coolant System Piping Design for Deep Hole Drilling Machines
Piping design is where most coolant system installations go wrong. I have walked into shops with a $50,000 high-pressure pump and $300 worth of undersized pipe fittings that turned the whole investment into a 600 psi system instead of the designed 1,000 psi. The piping carries the coolant, but it also creates pressure losses that compound with every fitting, bend, and length of tube. Pressure Drop Fundamentals Every component in the coolant path adds resistance. The pressure drop through a system is proportional to the flow rate squared. Doubling the flow quadruples the pressure loss through the piping. This matters enormously in deep hole drilling because the flow rates are high and the pressure requirements are tight. ...
