How many kinds of stainless steel tubes are polished?
- Aug 31, 2018 -

Mechanical polishing is a kind of polishing method which gets smooth surface by cutting and removing the convex part after polishing. In general, the polishing method uses oil-stone strips, wool wheels, abrasive paper and so on. It mainly operates by hand. Special parts such as the surface of the revolving body can be used with auxiliary tools such as turntable. Super-precision lapping and polishing can be used if the surface quality requirements are high. The way. Ultra-precision polishing is the use of special abrasive tools, in the abrasive containing polishing fluid, compacted on the surface of the workpiece is processed, high-speed rotational motion.

The basic principle of electropolishing is the same as that of chemical polishing, that is, to smooth the surface by selectively dissolving the tiny projections on the surface of the material. Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better.

The workpiece is placed in the suspension of abrasive and placed together in the ultrasonic field. The abrasive is grinded and polished on the workpiece surface by the oscillation of ultrasonic wave. Ultrasonic machining has little macroscopic force and will not cause deformation of workpiece, but the manufacture and installation of tooling are more difficult. Ultrasonic machining can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration stirring solution is applied to remove the dissolving product from the surface of the workpiece, and the corrosion or electrolyte near the surface is uniform. The cavitation of ultrasonic wave in the liquid can also inhibit the corrosion process, which is conducive to surface brightening.
