Diamond grinding polishing should pay attention to what aspects?

Diamond polishing should pay attention to what?

(1) the polishing must as far as possible in the light under the pressure of pre hardened steel parts and especially polishing with a fine abrasive polishing paste. In the use of #8000 polishing paste, the commonly used load for 100~200g/cm2, but to maintain the accuracy of this load is difficult to do. In order to easier to do this a little can do a thin and narrow handle in the wood, such as with a copper sheet; or in the bamboo trim part and make it more flexible. This can help to control the polishing pressure to ensure that the mold surface pressure will not be too high.

(2) when a diamond is used for grinding and polishing, it is not only the working surface, but also the worker's hands must be carefully cleaned.

(3) each polishing time should not be too long, the time is short, the effect is better. If for too long will cause the polishing process of the "orange peel" and "pitting".

(4) in order to obtain high quality polishing effect, it is easy to heat the polishing method and the tool should be avoided. For example: polishing polishing wheel, polishing wheel heat generated is likely to result in the "orange peel".

(5) when the polishing process is stopped, it is important to ensure that the surface is clean and carefully remove all the grinding agents and lubricants, and then spray a layer of mold anti rust coating on the surface.

Polishing technology is still the main reason why the polishing quality is influenced mainly by the mechanical polishing. In addition, also with the mold material, polishing before the surface condition, the heat treatment process and so on. The quality of steel is a prerequisite for good polishing quality, if the hardness of the steel surface is uneven, there are differences in the characteristics, often resulting in the difficulty of polishing. All kinds of inclusions and air holes in steel are not conducive to polishing.
