Deburring machining process method for bulb tube part of CT (Computed Tomography) machine

Abstract

The invention discloses a deburring process method for a bulb tube part of a CT (computed tomography) machine, which can realize deburring of the bulb tube part of the CT machine without a polishing solution, can avoid the sparking phenomenon caused by the action of high voltage during subsequent use, can prolong the service life of the bulb tube part of the CT machine, can avoid performance reduction of the bulb tube part of the CT machine, and can improve the production efficiency of the bulb tube part of the CT machine. The method is realized based on milling machine processing, the milling machine comprises a milling cutter, the cutting edge of the milling cutter is arc-shaped, and the method comprises the following steps: S1, enabling the arc surface of the arc-shaped cutting edge of the milling cutter to be in corresponding contact with the to-be-processed surface of the bulb tube part; and S2, a milling cutter is driven by a milling machine machining center main shaft to extrude the to-be-machined surface of the bulb tube part, so that the burrs are in press fit with a surface material of the bulb tube part.

As the main equipment of the hospital, the CT machine has a long continuous working time and a large loss, and its core component, the tube, is prone to failure. Surface treatment operations such as deburring

[0003] The traditional deburring processing method for CT machine tube parts is grinding machine polishing. Currently, commonly used grinding machines include honing machines, ultra-finishing machine tools, abrasive belt grinders, grinding machines and polishing machines, etc., but grinding machines use abrasive tools to process the workpiece surface During grinding, it is necessary to add polishing liquid (polishing agent) such as diamond, silicon dioxide or alumina to improve the grinding efficiency and ensure that the burr is effectively removed. However, after polishing, the polishing liquid is easy to remain and embedded in the CT machine ball. On the surface of tube parts, in the subsequent actual use process, the residual polishing liquid is affected by the high voltage in the vacuum environment of the CT machine to cause sparking. The sparking phenomenon not only damages the surface of the tube parts of the CT machine, but also reduces its service life. Moreover, it is easy to reduce the performance of the tube parts of the CT machine and affect the clarity of the final X-ray image.
