(1) Choose different types of refurbished machines and grinding, polishing effect will be affected by various factors according to the needs and experience: stone materials, grinders weight, weight, speed, whether the water and the amount of water, grinding type, quantity, grinding particle size, grinding time and experience, and so on;
(2) If the stone face serious injury, to use 3JKP, 4JKP metal grinding (notch piece) polished, then press 30 # 50 # 150 # 300 # 500 # 1000 # 2000 # 3000 # sequence grinding;
(3) If the stone surface damage is not serious, you can start selecting from grinding higher granularity and the actual situation may choose to skip;
(4) experienced technicians, mill finished No. 3000 # grinding, the stone surface brightness can reach 60 ° -80 °, brightness of up to 80 ° -90 ° using a polished granite floor and DF polished crystal surface treatment above, sponge polished marble floor polishing FP6 better treatment effect;
(5) the use of high granularity grinding grinding process is appropriate to reduce water consumption per finished grinding replaced a grit before grinding, it is recommended to clean the face, otherwise it will affect the grinding effect;
(6) Garley Diamond Polishing Pads Polishing Pads and uses essentially the same, but with a longer life and better surface smoothness.
Dark marble, granite floor grinding renovation after polishing, can not fully restore the original color, or coarsely ground remained scratches, or after repeated polishing, stone floor can not recover the original sharpness and brightness, you I encountered such a situation?
Why do these appear above situation? This is mainly because grinding is a problem, the problem did not follow the norms grind produced. Some people think that the focus of grinding notches and polished, as long as the notches and polished handled well, grinding a little rough, jump, grind and so on, can be solved in time polishing, polishing a few more, you can cover these issues If you want the truth of this, then the above problems will not arise.
To put an end to those above a similar situation, we should pay attention to the following questions when grinding aspects.
1, to establish the concept of progressive grinding. Must be progressively grinding stone grinding, polishing after # 50, # 150 polishing, and so on, the grinding stone which is particularly important for the dark. If you jump, grinding, polishing finish as # 50 on the exchange of # 300 grinding grinding, it certainly will not be back on top of the color problems. A mesh to eliminate scratches on a mesh, which is grinding in the production design make it good. Maybe someone objected, operating a number of stone when I jump number, did not appear you said residual scratches, but I tell you this is just one example, your operation is certainly light-colored stone, or hardness of stone low, easy to remove scratches, lighter color scratch is not easy to see, if you take a magnifying glass to observe certain there will be scratches.
2, coarse grinding to grind through. When roughing is carrying 30 or # 50 # This Road grinding, must be a good grinding, grinding through. What is this concept? Some people making notches along the seam grinding mill usually more general, but the polished stone surface of the plate may have a bright portion between the plates, which is not grind through. Each has a grinding capacity of self-eliminate scratches, if not 50 # grinding mill thoroughly, it will increase to eliminate 50 150 # # scratch difficulty.
3, there must be milled concept to quantify. Many workers during grinding no quantitative concept, polished till 50 #, 150 # 50 # to grind several times to eliminate scratches clean, no quantitative concept, how to do it, is by experience, or racking our brains. But a different stone, a few times a different scene operation there is a difference, you may experience the past will not work on this project, we want to conduct on-site experiments. Let us not only to quantify the concept of problem solving, but also more with less!
When we want to progressively grind grinding, not only to progressively eliminate scratches, but because each channel has its own grinding function. Like # 150 grinding to eliminate notches polished rough grinding scratches, # 300 grinding has the ability to return to the color, but it must be renovated have this feature, # 500 grinding have the ability to order sheet for roughing good finishing fine grinding, grinding to prepare polishing. Polishing step is the key to the whole project care, crystallization polishing just icing on the cake.
