Machining process for martensitic stainless steel medical device part

Abstract

The invention discloses a machining process for a martensitic stainless steel medical device part. The machining process comprises a step of preparing a medical device after cold rolling treatment isperformed on a martensitic stainless steel circular disc for nine times, wherein the process of performing the cold rolling treatment for nine times further comprises a step of performing annealing treatment on the martensitic stainless steel circular disc for five times; compared with the former cold rolling treatment, the deformation rate of the cold rolling treatment each time is less than or equal to 60 percent; and the annealing temperature is 800 to 900 DEG C. The machining process for the martensitic stainless steel medical device part is used for machining of a medical device part in medical industry; the process of performing CNC surface polishing after adopting linear cutting in the past is changed; the machining time is greatly shortened; the production efficiency is improved; and the production cost is reduced by a half.

Description

Technical field [0001] The invention relates to a processing technology of martensitic stainless steel medical device parts. Background technique [0002] At present, in the medical industry, some parts of medical equipment (such as endoscopic cutting staplers and the nail box base of disposable nail boxes) are made of stainless steel, such as martensitic stainless steel or austenitic stainless steel. The current processing method All are wire cutting, with serious material waste and high cost, and CNC surface polishing is required after wire cutting, which requires long processing hours and low production efficiency in mass production. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings in the prior art and provide a process for processing martensitic stainless steel medical device parts, which is used in the processing of medical device parts in the medical industry, and changes the CNC surface after wire cutting. The polishing...
