Increasing Machine Tool Productivity with High Pressure Cryogenic Coolant Flow.

摘要

THe Institute of Advanced Manufacturing Sciences, Inc. (IAMS) in Cincinnati has conducted a program to evaluate the Flojet high pressure cryogenic coolant system on a number of common and difficult-to-machine materials and to analyze the economic benefits. This research contract was awarded under the Air Force's Machine Tool Products and Processes Program Research and Development Announcement (PRDA). The program included a continuing forum with interested industrial representatives to disseminate information about the system and to identify questions and concerns from potential users that might be addressed in testing. The Flojet system, a product of PXI, Incorporated, has the potential to significantly improve operations in the metal-cutting industry. It is a coolant delivery system that produced a very high pressure stream of coolant and a parallel stream of CO2 which are aimed at the cutting zone. It is designed to provide improved chip-breaking, longer tool life, reduced cutting forces, and improved workpiece quality. The inventor and several other parties formed PXI, Inc. to market and continue development of the system which presently has only a small installed base of industrial users.
