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
Technical field
The invention belongs to casting technology field, be specifically related to a kind of 2Cr13 stainless steel turning technique.
Background technology
2Cr13 belongs to martensitic stain less steel, and its intensity is high, plasticity good, hardness is high, poor thermal conductivity, is out of shape also large in process.And work hardening is serious when cutting, resistance to cutting is large, and cutting temperature is high, causes tool wear serious, sharpening increased frequency, adds down time and dress cutter time, reduces productivity ratio.Meanwhile, because plasticity is good, in process, very easily sticky cutter, produces built-up edge, causes the change of workpiece size and affect surface roughness, and chip is not easily curling and fracture, and easy damaged workpiece machined surface, affects the quality of workpiece.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of 2Cr13 stainless steel turning technique is provided, decrease number of changing knife, enhance productivity.
2Cr13 stainless steel turning technique provided by the invention, comprises the following steps:
(1) heat treatment changes material hardness: 840 ~ 900 DEG C of quenchings, and insulation 2 ~ 4h, drops to 600 DEG C with the cooling velocity of≤25 DEG C/h, air cooling of coming out of the stove;
(2) modified: 1000 ~ 1050 DEG C of quenchings, then high tempering 700 ~ 800 DEG C, air cooling after insulation 2 ~ 6h;
(3) alloy cutter material: the materials such as YG6, YG8, YT15, YT30, YWl, YW2;
(4) lathe tool anterior angle γ
0: 10
0~ 20
0, lathe tool relief angle α
0: 5
0~ 8
0, lathe tool cutting edge inclination λ
0:-10
0~-30
0, cutting edge roundness surface roughness R
0: 0.4 ~ 0.2 μm;
(5) cutting data: between 0 ~ 3mm.
2Cr13 stainless steel turning technique provided by the invention, its beneficial effect is, overcome the very easily sticky cutter overcoming and often have in existing technique, produce built-up edge, cause the change of workpiece size and affect surface roughness, and chip is not easily curling and fracture, the shortcomings such as easy damaged workpiece machined surface, decrease number of changing knife, enhance productivity, save cost.
Detailed description of the invention
Below in conjunction with an embodiment, 2Cr13 stainless steel turning technique provided by the invention is described in detail.
Embodiment
The 2Cr13 stainless steel turning technique of the present embodiment, comprises the following steps:
(1) heat treatment changes material hardness: 850 DEG C of quenchings, and insulation 3h, drops to 600 DEG C with the cooling velocity of 20 DEG C/h, air cooling of coming out of the stove;
(2) modified: 1000 DEG C of quenchings, then high tempering 750 DEG C, air cooling after insulation 5h;
(3) alloy cutter material: YT30 material;
(4) lathe tool anterior angle γ
0: 12
0, lathe tool relief angle α
0: 6
0, lathe tool cutting edge inclination λ
0:-15
0, cutting edge roundness surface roughness R
0: 0.3 μm;
(5) cutting data: 2mm.
