The rule here is 10 gpm per inch of drill diameter. A .500inch diameter drill needs 5 gpm to achieve the high pressure effect; a .250inch drill needs gpm. The most frequent problem is coolant holes that are just too small. The drill must be capable of passing enough coolant, or it just won't perform properly.

Grinding Under Pressure. Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal ...

Work hardening of materials is a condition that should be avoided while machining. It is caused when heat generated by the cutting tool transfers to the workpiece material and causes plastic deformation. The process is similar to a heat treatment of the workpiece but on a lower scale. When a part work hardens during machining, its surface ...
