1、机械抛光

1. Mechanical polishing

济南模具厂提示机械抛光是靠切削、材料表面塑性变形去掉被抛光后的凸部而得到平滑面的抛光方法，一般使用油石条、羊毛轮、砂纸等，以手工操作为主，特殊零件如回转体表面，可使用转台等辅助工具，表面质量要求高的可采用超精研抛的方法。

Jinan mould factory suggests that mechanical polishing is a polishing method to get a smooth surface by cutting, plastic deformation of material surface and removing the convex part after polishing. Generally, oilstone strip, wool wheel, sandpaper, etc. are used. Manual operation is the main method. Auxiliary tools such as turntable can be used for special parts such as swivel surface. Superfinishing polishing method can be used for those with high surface quality requirements.

2、化学抛光

2. Chemical polishing

化学抛光是让材料在化学介质中表面微观凸出的部分较凹部分优先溶解，从而得到平滑面。这种方法的主要优点是不需复杂设备，可以抛光形状复杂的工件。

Chemical polishing is to make the micro protruding part of the material surface dissolve preferentially than the concave part in the chemical medium, so as to obtain a smooth surface. The main advantage of this method is that it doesn't need complex equipment and can polish the workpiece with complex shape.

3、电解抛光

3. Electropolishing

电解抛光基本原理与化学抛光相同，即靠选择性的溶解材料表面微小凸出部分，使表面光滑。与化学抛光相比，可以阴极反应的影响，效果较好。

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

4、超声波抛光

4. Ultrasonic polishing

将模具配件放入磨料悬浮液中并一起置于超声波场中，依靠超声波的振荡作用，使磨料在工件表面磨削抛光。超声波加工宏观力小，不会引起工件变形，但工装制作和安装较困难。

The mold parts are put into the abrasive suspension and placed together in the ultrasonic field, and the abrasive is ground and polished on the workpiece surface by the ultrasonic oscillation. The macro force of ultrasonic machining is small, which will not cause the deformation of the workpiece, but it is difficult to make and install the tooling.

5、流体抛光

5. Fluid polishing

流体抛光是依靠高速流动的液体及其携带的磨粒冲刷工件表面达到抛光的目的。常用方法有：磨料喷射加工、液体喷射加工、流体动力研磨等。

Fluid polishing relies on the high-speed flow of liquid and abrasive particles to wash the workpiece surface to achieve the purpose of polishing. The common methods are abrasive jet machining, liquid jet machining, hydrodynamic grinding and so on.

6、磁研磨抛光

6. Magnetic abrasive polishing

磁研磨抛光是利用磁性磨料在磁场作用下形成磨料刷，对工件磨削加工。这种方法加工效率高，质量好，加工条件容易控制，工作条件好。

Magnetic abrasive polishing is to use magnetic abrasive to form abrasive brush under the action of magnetic field to grind workpiece. This method has the advantages of high efficiency, good quality, easy control of processing conditions and good working conditions.
