Problems solved by technology

Moreover, the work hardening is severe during cutting, the cutting resistance is large, and the cutting temperature is high, resulting in severe tool wear, increased grinding times, increased parking time and tool loading time, and reduced productivity.
At the same time, due to the good plasticity, it is very easy to stick to the knife during processing, resulting in built-up edge, causing changes in the size of the workpiece and affecting the surface roughness, and the chips are not easy to curl and break, easy to damage the processed surface of the workpiece, and affect the quality of the workpiece

Embodiment

[0018] The 2Cr13 stainless steel turning process of the present embodiment comprises the following steps:

[0019] (1) Heat treatment to change the hardness of the material: quenching at 850°C, heat preservation for 3 hours, cooling down to 600°C at a cooling rate of 20°C / h, and air-cooling when out of the furnace;

[0020] (2) Quenching and tempering: Quenching at 1000°C, then tempering at 750°C at high temperature, holding for 5 hours and then air cooling;

[0021] (3) Alloy tool material: YT30 material;

[0022] (4) Turning tool rake angle γ 0 :12 0 , turning tool relief angle α 0 :6 0 , turning blade inclination angle λ 0 :-15 0 , tool edge surface roughness R 0 : 0.3μm;

[0023] (5) Cutting amount: 2mm.

Abstract

The invention discloses a 2Cr13 stainless steel turning process; and in the turning of a 2Cr13 stainless steel part, such several aspects as heat treatment of materials, selection of cutter materials, cutter cutting angles and cutting liquid are properly treated. The 2Cr13 stainless steel turning process overcomes such defects as easy cutter sticking, generation of built-up edges, workpiece size change, influence on the surface roughness, difficult winding and breaking of chips and easy damage of machined workpiece surfaces.

Description

[0001] technical field [0002] The invention belongs to the technical field of casting, and in particular relates to a turning process of 2Cr13 stainless steel. [0003] Background technique [0004] 2Cr13 belongs to martensitic stainless steel, which has high strength, good plasticity, high hardness, poor thermal conductivity, and large deformation during processing. Moreover, the work hardening is severe during cutting, the cutting resistance is large, and the cutting temperature is high, resulting in severe tool wear, increased sharpening times, increased parking time and tool loading time, and reduced productivity. At the same time, due to the good plasticity, it is very easy to stick to the knife during processing, resulting in built-up edge, causing changes in the size of the workpiece and affecting the surface roughness, and the chips are not easy to curl and break, easy to damage the processed surface of the workpiece, and affect the quality of the workpiece ....
