The contact surface of the reducing detection probe mechanism 3 and the shell 1 is polished; if the outer surface of the reducing detection probe mechanism 3 is not polished, unnecessary friction force is generated between the reducing detection probe mechanism 3 and the shell 1, and the detection result is inaccurate; polishing refers to a processing method for reducing the roughness of the surface of a workpiece by using mechanical, chemical or electrochemical actions to obtain a bright and flat surface, and is a modification processing of the surface of the workpiece by using a polishing tool and abrasive particles or other polishing media.
Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or a mirror surface gloss, and sometimes also serves to eliminate gloss (matting). Generally, a polishing wheel is used as a polishing tool, the polishing wheel is generally made of a laminate of a plurality of layers of canvas, felt or leather, both sides of the polishing wheel are clamped by metal disks, and a rim of the polishing wheel is coated with a polishing agent formed by uniformly mixing a fine powder abrasive and grease or the like. When polishing, a polishing wheel rotating at a high speed (peripheral speed of 20 m/sec or more) is pressed against a workpiece to cause the abrasive to roll and micro-cut the surface of the workpiece, thereby obtaining a bright processed surface, and when a non-greasy matte polishing agent is used, the bright surface can be matte to improve the appearance.
The polishing mode comprises the following steps: mechanical polishing, chemical polishing, electropolishing, ultrasonic polishing, fluid polishing, and magnetic abrasive polishing. Among them, mechanical polishing and chemical polishing are widely used.
Mechanical polishing, in which a smooth surface is obtained by a cutting method and a method of plastically deforming the surface of a material to remove a polished convex part, generally, a oilstone strip, a fleece wheel, sand paper and the like are used, manual operation is mainly used, special parts such as the surface of a revolving body can be used, auxiliary tools such as a rotary table and the like can be used, and a super-finishing method can be adopted when the surface quality requirement is high.
And (3) performing chemical polishing, wherein microscopically convex parts of the material in a chemical medium are dissolved preferentially than concave parts of the material, so that a smooth surface is obtained. The method has the main advantages that complex equipment is not needed, workpieces with complex shapes can be polished, a plurality of workpieces can be polished simultaneously, and the efficiency is high. The core problem of chemical polishing is the preparation of polishing solution.
The manner of polishing is not limited in this application.
