ABSTRACT:
The herein-proposed method of cutting solids of revolution by a rotary tool having circular cutting lip resides in that the tool is imparted feed motion, while its rotation results from the interaction of said tool with the rotating workpiece being machined. Prior to bringing the tool in contact with the surface being machined the tool is imparted a positive rotation at a speed differing by not more than 20 percent from the tool working speed, in the same direction as the tool working motion. The rotary tool for carrying said method into effect is shaped as a solid of revolution having a circular cutting lip and held on a spindle provided with a through center bore for the stream of coolant to feed therethrough, the screw-type wind turbine being provided in said spindle bore.
