Title:
PRECISION NUMERICAL CONTROL MACHINING METHOD FOR TITANIUM ALLOY THIN-WALLED LENS BARREL PART
Document Type and Number:
WIPO Patent Application WO/2023/070921
Kind Code:
A1
Abstract:
Provided is a precision numerical control machining method for a titanium alloy thin-walled lens barrel part (1), comprising the following steps: S1: performing rough turning, reserving a margin of 30 mm at one end of a blank close to an end surface of a part (1), and carrying out a heat treatment; S2: machining the margin in step S1, and machining a process clamping platform (5); S3: mounting the processed part (1) in step S2 on a first self-made workpiece (2), carrying out semi-finish turning on a barrel body (6), and carrying out milling on the side close to the process clamping platform (5); S4: separating the part (1) from the first self-made workpiece (2), placing a supporting block into an inner hole of the part (1), and cutting the process clamping platform (5) of the part (1); S5: machining an outer contour of the part (1) and machining a process threaded hole; S6: mounting the part (1) on a second self-made workpiece (7), and carrying out finish turning; and S7: machining the process threaded hole into a through hole. In the precision numerical control machining method for a titanium alloy thin-walled lens barrel part (1), deformation does not easily occur, and the quality of the part (1) is high.
