Ultrathin part machining method

Abstract

The invention discloses an ultrathin part machining method. The ultrathin part machining method comprises the following steps: (S1) lower materials of parts are lengthened by 1-2 mm; and the outer diameters are increased by 0.5-1 mm; (S2) one end surfaces are turned; the depths of inner holes are increased according to the sizes of the parts; the diameters of the inner holes are upper limits of the tolerances; internal thread grooves are formed in the ends of the inner holes; and the sizes of the threads are designed according to the size requirements of the parts; (S3) auxiliary tools are assembled with parts to be machined; (S4) the parts are formed by turning; (S5) sharp cutters with sharp right single edges are selected for cutting step places of the threads according to the size requirements; (S6) finished parts are taken down from thread core rods; and (S7) both inspection and warehousing are performed; and the auxiliary tools used in the step (S3) comprise the thread core rods and clamping devices. The parts are machined through design of the auxiliary tools; the parts to be machined are assembled on the auxiliary tools in use; the whole auxiliary tools and the parts to be machined are fixedly clamped on a lathe, so that the clamping mode is simple; after clamping, the machining vibration, the destruction and the deformation are eliminated; the machining precision and the product pass percent are improved; and ultrathin parts with single edges less than 1 mm can be machined.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for processing ultra-thin parts with a single side of less than 1 mm on a numerically controlled lathe. Background technique [0002] In the field of mechanical processing, thin-walled parts are widely used in various mechanical equipment due to their compact structure, light weight and special performance. However, thin-walled parts have low rigidity and weak strength, and are difficult to clamp during processing. , Vibration and cutting heat generated during cutting are likely to cause deformation of thin-walled parts and other factors. This affects the dimensional accuracy and shape accuracy of the workpiece, which is also a difficult point in the processing of thin-walled parts. [0003] Lathes or CNC lathes generally use the following four processing methods for thin-walled parts: processing by split sleeves, full-shaped soft cl...
