     · For grinding an established flow rate model to effectively cool the process is 2 gpm per spindle horsepower. Therefore a 5-hp cycle requires a 10-gpm coolant flow rate. This stream has to be correctly aimed for effective grinding at this flow rate. Coherent-jet nozzles also offer a high degree of adjustability and stiffness once aimed.
