Abrasive polishing method described six

1, the mechanical polishing: mechanical polishing is plastically deformed by

the cutting surface is polished to remove the convex portions obtained by a

smooth surface polishing method  ceramic belt generally used Whetstone, wool wheel,

sandpaper, abrasive belt, nylon wheels, manual operation is Lord, special

parts such as body surface rotation, you can use the turntable and other

aids, high surface quality requirements can be thrown over lapping method.

Super abrasive lapping and polishing is a special abrasive in polishing

liquid containing abrasive, and  sanding paper roll pressed on the surface of the workpiece to be

machined for high-speed rotation. The polishing method is the highest age.

Optical lens mold often use this method.
    2, chemical polishing: chemical polishing is to make the material in the

chemical medium surface micro-convex and concave portions preferential

dissolution of some of the more, resulting in a smooth surface. The main

advantage of this method is that the device does not need a complex, the

complex shape of the workpiece can be polished, many workpieces can be

simultaneously polished, high efficiency. The core problem is formulated

chemical polishing polishing solution.
    3, electrolytic polishing: electrolytic polishing and chemical polishing

the same basic principle, namely by selectively dissolving the surface of

fine convex portions, the surface smooth. Compared with chemical polishing,

can eliminate the impact of the cathodic reaction, the effect is better.

Electrochemical polishing process of  coated abrasive leveling the macro and micro leveling.
    4, ultrasonic polishing: the workpiece into the abrasive suspension and

placed in an ultrasonic field together, relying on the role of ultrasonic

oscillations, so that the abrasive grinding and polishing the surface of the

workpiece. Ultrasonic machining macroscopic force is small, does not cause

deformation of the workpiece, but the tooling fabrication and installation

more difficult. Ultrasonic machining can be combined with chemical or

electrochemical methods. In the etching solution, based on the electrolysis,

the solution was stirred and then applying ultrasonic vibration to the

workpiece surface from the lysate, or near the surface of the electrolyte

uniform corrosion; ultrasonic cavitation in a liquid is also possible to

suppress the corrosion process, in favor of the surface luster.
    5, fluid polishing: polishing fluid is relying on high-speed flow of

liquid abrasive scouring and polishing the surface to achieve the purpose of

carrying. Common methods are: silicon carbide abrasive jet machining, liquid

jet machining, grinding fluid power. Fluid energy mill is driven by hydraulic

medium that carry high speed abrasive liquid flow through the reciprocation

of the workpiece surface. Medium used mainly in low pressure flowing through

specific compounds and mixed with good abrasive made from silicon carbide

abrasives abrasive powder can be used.
