The purpose of this investigation is an invention of theory and technics on surface roughness ≈ O, roundness ≈ O and cylindricity ≈ O machining. This is analyzed according to the principle of making a precise circle. In this study, the method of precision cylindrical machining can be created by combining the insensitive vibration cutting mechanism, (40 Hz+30 kHz) superposition superfinishing, the main spindle system with the air bearing and the carriage system with the pneumatic fioating slideway. The concrete methods are as follows : In the first process, the work which is chucked on the main spindle with air bearing is machined as acting a continuously and systematically pulsating cutting force by the ultrasonic vibration cutting mechanism. In the following process, the work is finished by the newly developed (40 Hz+30 kHz) superposition superfinishing device. Key points of the technics are as follows : The one is a contrivance of the carriage system with the pneumatic floating slideway for making high straightness and rigidity. The other is a contrivance for making accurate motions and no reaction of the (40 Hz+30 kHz) superposition superfinishing device. After all, to actualize machining surface roughness of 0.05-0.15 μmR_<max>, roundness of 0.02-0.1 μm, cylindricity of ≈ 0-0.5 μm/50 mm are succeeded in work material of aluminum alloy, brass, carbon steel, stainless steel and hardened steel (HRC 35,39). Therefore, it is found that the super precision cylindrical machining can be realized by means of this new machining process and its lathe.
