CYLINDER INSIDE DIAMETER COMPLEX PROCESSING TOOL

The present invention relates to a complex processing tool for an inner circumference of a cylinder to process an inner side of a tube-shaped cylinder and, more specifically, to a complex processing tool for an inner circumference of a cylinder, including: a rod passing through the inside of a cylinder in a longitudinal direction; a skiving part mounted at the front end of the rod to skive the inner circumference of the cylinder while the rod moves forward; a drive shank mounted at the rear end of the rod to be connected to a power source for linear reciprocation or rotation in order to allow the skiving part to skive the inner circumference of the cylinder; and a burnishing part mounted on the rod between the skiving part and the drive shank to smoothen the inner circumference of the cylinder, which has been skived by the skiving part, while the rod moves backward. Therefore, the complex processing tool for an inner circumference of a cylinder shortens a process time and improves productivity by allowing the inner circumference of the cylinder to be extended after the skiving step without the replacement of a processing tool.
