Embodiment Construction

[0040] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0041] Such as figure 1 As shown, a processing method for austenitic stainless steel parts, selects 06Cr18Ni11Ti austenitic stainless steel material, and processes a part whose shape is a body of revolution and whose shape is a parabolic curved surface 3. Cavities are provided at both ends of the parabolic curved surface 3 .

[0042] Include the following steps:

[0043] ①Blanking: blanking stainless steel rod 06Cr18Ni11Ti, after blanking, remove flash and burrs;

[0044] ②Turning: Turning stainless steel rod 06Cr18Ni11Ti to make parts;

[0045] ③Milling processing: Milling the inscribed circle of the part, making the cavity, removing the processing burr after milling, positioning with the inscribed circle, milling another cavity, and removing the processing burr after milling;

[0046] ④Chemical passivation: Clean the parts an...

Abstract

The invention provides an austenitic stainless steel part machining method. A 06Cr18Ni11Ti austenitic stainless steel material is selected and used, a part with a revolution-solid shape and paraboliccurve appearance is machined, and mold cavities are formed in the two ends of a parabolic curve. By means of the austenitic stainless steel part machining method, the cutting machinability of the 06Cr18Ni11Ti austenitic stainless steel part is improved by reasonably arranging process routes and optimizing tool materials, the best tool sharpening angle, reasonable cutting parameters and a cutting lubrication fluid; the machining process is made to be compact, the turnover number is less, the production efficiency is improved, the production cost is reduced, tool wear is reduced, and the tool service life is prolonged; and meanwhile, the surface machining quality of the 06Cr18Ni11Ti austenitic stainless steel part is improved, the machining cycle of the part is shortened, the production costis reduced, and the austenitic stainless steel part machining method has great economic and practicability in production practice.

Description

technical field [0001] The invention relates to a processing method for austenitic stainless steel parts, belonging to the technical field of processing stainless steel parts. Background technique [0002] With the rapid development of my country's science and technology and industry, stainless steel is more and more widely used in aviation, aerospace, shipbuilding, chemical and construction industries, which can reduce the surface protection and anti-rust measures of parts, and reduce the failure probability of parts. Austenitic stainless steel is the most widely used. Austenitic stainless steel is a series of steel grades obtained by adding nickel, manganese, nitrogen and other austenite forming elements to ferritic stainless steel containing 18% chromium. [0003] 06Cr18Ni11Ti belongs to austenitic stainless steel, which has excellent mechanical properties, high strength, good corrosion resistance and oxidation resistance in the atmosphere or in corrosive media, although 0...
