HIGH-SPEED PULSATING TYPE TURNING PROCESSING METHOD AND DEVICE FOR IMPLEMENTING THE METHOD

摘要

A high-speed pulsating type turning processing method and a device for implementing the method, during turning process, the contact manner between a tool and a workpiece (1) is improved from the continuous contact mode to the pulsating contact mode. By means of the movement of the tool, the relative linear cutting speed of a blade (5) between the workpiece (1) is higher than the surface speed of the workpiece and high-speed turning is implemented. Further, implementing active cooling to the tool before and after the turning and controlling the temperature of workpiece (1) material before the turning expand the processing scope of the tool material and avoid the burden of heat-resistant caused by temperature rise of the tool.
