Increasing the productivity of milling processes by focused supply of high pressure coolant


The major purpose of the research project is the significant increase of productivity and process stability for milling processes with tools that are equipped with indexable inserts compared to the current state of the art by developing a high pressure coolant supply with a focused coolant jet. For this purpose, the well explored positive influence of high pressure coolant supply on the chip breakage is used among others to develop tools with smaller spiral flutes and as a result, higher numbers of cutting teeth. The productivity in milling of steel and titanium materials with tools that feature multiple rows can be increased by more than 25 % compared to the current state of the art by using tools with higher numbers of cutting teeth.
