How does the automatic polishing machine equipment polish and polish the zinc alloy die-casting parts? The surface of zinc alloy die-casting parts will generally have serious cracks, bubbles, shrinkage holes, looseness, etc. How can we solve these problems? The polishing machine design first uses a thousand impeller or abrasive belt to remove the surface defects such as surface burrs, parting lines and flash edges of the workpiece, and the polishing machine obtains a substantially flat and smooth surface. Then use the hemp wheel or cloth wheel to further smooth the polishing marks on the surface of the product (the diameter of the cloth wheel is 50-400mm, the maximum peripheral speed is not more than 2500m/min, and the small parts are low speed of 1100~1400m/min. The adhered abrasive on the cloth wheel is 0.069-0.045 mm, and the sharp angle is to be inverted to use iron oxide.

As the polishing paste for the main polishing paste, it must not be dry. When polishing, it should be carried out in one direction, the wear marks should not cross, the polishing pressure should not be too large, and the grinding amount should not be too large. Finally, the final fine polishing machine is used to polish the product with a cloth wheel or a pearl cloth wheel. Give the product a shiny, smooth, scratch-free surface. (Generally used white wax and green wax polishing paste. The pressure should not be too large. In order to avoid pitting or scorching phenomenon) The above is the general polishing machine process, and the process used for the shape and material of the product will be different.
