The deformation of thin-walled sleeve precision machinery parts processing precautions in precision machinery parts processing, is one kind is thin-wall sleeve parts, in the process of precision machining
, often due to clamping force, cutting force and cutting heat caused by the deformation, the influence of the sleeve precision metal processing parts precision is lower.
If the thin-wall sleeve need heat treatment, improper process arrangement, can also cause unrecoverable deformation.
In order to prevent deformation of thin-walled sleeve, can take the following measures: 1.
Reduce the influence of clamping force on the deformation.
Clamping force should not be focused on a portion of the workpiece, should make its distribution in the area of the larger, in order to make the pressure of the workpiece per unit area is small, thus reducing its deformation, such as cylindrical workpiece with chuck clamping, can use soft jaw, to increase the width and length of jaw.
Using axial clamping workpiece fixture: 3.
On the workpiece to strengthen rigidity of auxiliary chime, precision machinery parts processing when the use of special structure of card claw clamping.
Reduce the influence of cutting force of deformation: 5.
Reduce the radial force, usually with the aid of increase the main Angle of the cutting tool to achieve.
Inner surface processing at the same time, the radial cutting force cancel each other out.
Separately from the rough and finish machining, can make the deformation occurring during rough machining in finishing can be corrected.
Artifacts in the process of machining by cutting to swell after hot deformation, thus affecting the accuracy of precision machinery parts processing, in order to reduce the influence of thermal deformation of machining accuracy, and should be in the rough and finish machining with sufficient cooling time between, and inject enough cutting fluid during machining.
After heat treatment on the sleeve precision machinery parts processing the influence of the deformation is large, in addition to improve the method of heat treatment, when arranging heat treatment process, should be arranged before finishing, so that the heat treatment of deformation in the later process to be corrected.
Separately from the rough and finish machining, the deformation occurring during rough machining in finishing can be corrected.
