ARRANGEMENT OF A DIAMOND-TYPE MILLING MACHINE FOR DRY ADIABATIC MACHINING

摘要

A transfer device for a very high speed adiabatic face milling machine whose configuration and operation provide a highly efficient machining process suitable for production manufacturing conditions. The milling machine preferably operates at speeds of approximately 15,000 sfm and at efficiencies of approximately 7 cubic inches per minute per horsepower. The preferred milling operation is conducted without the use of cooling liquids, instead employing a chip removal system which enables the milling machine to operate truly adiabatically such that no heat is transferred to the workpiece or the cutter. The efficiency of the chip removal system is such that chip recutting is nearly eliminated and tool life is improved. The transfer device, by use of a transfer arm and associated grasping arms, locates the workpiece within a corresponding nesting slot defined by the grasping arms in order to accurately and securely move the workpiece between workpiece support structures so as to position opposing sides of the workpiece in the fixture for subsequent machining.
