Document Type and Number:
WIPO Patent Application WO/2004/089569
Kind Code:
A1
Abstract:
A method of processing a screw rotor, where a screw groove is formed by a tool (3) in the outer diameter portion of a rotating object (1) to be processed. The processing is made using a processing device by swinging a tool post (2) and moving it in the X axis, Y axis, and Z axis directions. The processing device has a bed (11), a C-axis headstock (12) provided on the bed (11), a C-axis main spindle (14) supported by the C-axis headstock (12) and rotating the object (1) to be processed having a hollow-cylindrical shape, a column (13) provided on the bed (11), the tool post (2) swingably supported by the column (13), and the tool (3) attached to the tool post (2).
