High precision processing of external surface of thin-walled pipe involves clamping pipe at one end, moving external processing tool axially along pipe from other end with relative rotation

摘要

The method involves clamping the pipe (10) only at one end and moving an external processing tool (26) axially along the pipe from the other end, whereby the pipe and the external processing tool are rotated relative to each other about the pipe axis and the pipe is addressed to the external processing tool. The other end of the pipe is centered at the start of processing using a centering pin (27). Independent claims are also included for the following: a processing machine for implementing the method.
