State of the Art in High Speed Machining with High Pressure Coolant

Abstract

High pressure coolant is expected to dramatically improve the machinability of difficult-to-machine materials and develop new strategic approaches to high speed machining. This paper reviews high speed machining technology with high pressure coolant with regard to chip breakage, reduction of tool wear and drilling technology without pecking cycles. The film boiling of coolant near the tool tip due to high tool temperature is discussed based on the results of cutting experiments of stainless steel.
