Thin wall of the support ring processing technology 1)

in order to prevent or reduce the deformation of thin wall support ring, the third handler and the corresponding measures should be taken.
(1) the workpiece coarse, fine cars, as far as possible some rough places car artifacts after cooling, eliminate possible thermal deformation processing time.
(2) the axial compression, change the clamping point, make the workpiece deformation. The clamp with positioning hole, because of the inner hole space, therefore on & amp; lt; Mm processed products should be the internal control, figure positioning plate positioning only I stay in machine tool processing profits, and product positioning in the axial groove, the minimum gap orifice radial groove processing, always make the internal and external pressure, to ensure that the design on the basis of the unity based, positioning and measurement datum in order to ensure product quality plate exchange products.
(3) the coarse and fine motor cooling fluid. Turning process, the cutting deformation and chips, the friction between tool and workpiece can produce a lot of heat. There is very overcast heat cutting of thin wall. Turn, therefore, in the proper selection of metal cutting fluid, make full use of the cooling fluid, not only reduces the cutting temperature, reduce the cutting force, cutting tool durability enhancement, also reduce the surface roughness value, reduces the cutting power artifacts from the cutting heat, little change, in the form and position error, ensure the quality of the parts. When using rough machining high speed steel cutting tools, the main field is to reduce cutting temperature, improve tool life, should choose mainly by metal cutting liquid cooling, such as low concentration emulsion. When using carbide rough machining tool, cutting fluid must be continuous, complete actor, generally have no cutting fluid. Is complete, the main effect of cutting fluid, is to improve the precision and reduce the workpiece surface roughness value, should choose to % % ion membrane liquid or emulsion cutting fluid concentration.
(4) reasonable selecting cutting parameters, reduce the deformation. Rough machining, knife can be used to increase quantity and feed diet of AP on the back of the building when turning to sort out the AP optional? Mm volume contents, feed speed is commonly? The 012 mm, even less. Apply for the cutting according to the workpiece material, diameter of workpiece, cutting tool material and point of view, within a certain range control, the general argument =? One hundred and twenty m/min, speed, and should be to prevent the resonance of the workpiece.
5. Reasonable use of the tool geometry. Turning thin-walled parts, should pay attention to choose the main Angle of Kr, axial force, or in the direction of the poor rigidity reduce the radial force, lambda s aggressive blade Angle, sharp blade grinding, rake Angle and back Angle should be accordingly. If complete tool krypton = °? °, krypton & amp; #; = °, °? αo= °，αo= °。 Precision tooling holes krypton = °, krypton & amp; #; = °, °? αo= °，αo= °? °.
