Abstract
The equal-pitch groove processing device (1) comprises transferring means (10), (40) for continuously transferring a workpiece (100) in an axial direction of the workpiece (100); processing tools (23), (33) in which cutting teeth (23a) of a thickness corresponding to a width of a groove to be processed are formed around an outer peripheral portion along a spiral path, and which is rotatively driven with the center of that spiral as an axis; and controlling means (70), (80) for synchronously operating the processing tools (23), (33) in such a manner that the workpiece (100) is transferred by a one-normal-pitch portion of the spiral while the processing tools (23), (33) undergo one revolution, whereby equal-pitch grooves are formed in the workpiece (100) by the cutting teeth (23a) of the processing tools (23), (33).
Claims6
An equal-pitch groove processing device characterized by comprising:
- transferring means for continuously transferring a workpiece along an axial direction of said workpiece;
- a plurality of processing tools arrayed along the direction of transverse of said workpiece, each said processing tool having a cutting tooth of a thickness corresponding to a width of a groove to be processed is formed in an outer peripheral portion along a spiral path, and which is rotatively driven with a center of said spiral path as an axis and wherein said processing tools are dispersed in an identical plane parallel with the axis of said workpiece in a direction of its transfer in such a manner as to be inclined in mutually different directions with respect to the axis of said workpiece in the direction of its transfer;
- and
- controlling means for synchronously operating said processing tool and said transferring means in such a manner that said workpiece is transferred by a one-normal-pitch portion of said spiral while said processing tool undergoes one revolution,
- whereby equal-pitch grooves are formed in said workpiece by said cutting tooth of said processing tool.
