1. Particle grinding: when the abrasive particles are polished from coarse to fine, the grinding traces on the stone surface will be very smooth, flat and delicate. When the depth reaches 110 μ m, the processed surface will have mirror luster, bright luster and bright color.
Particle grinding includes the following steps:
(1) Rough grinding: it requires deep cutting ability, high grinding efficiency, rough grinding line and rough grinding surface, mainly to remove the saw blade traces left by the previous process and grind the flatness and forming surface of the product in place;
(2) Semi finish grinding: remove rough grinding traces, form new fine lines, stone polishing machine processing surface smooth;
(3) Fine grinding: after fine grinding, the pattern, particle and color of the product have been clearly displayed, the surface is delicate, and there is a weak glossiness;
(4) Fine grinding: there is no trace in the visual inspection of the processed products. The surface is more and more smooth, glossiness is about 40 ~ 50 degrees;
(5) Polishing: the surface is as bright as a mirror, with a certain specular gloss (above 85 degrees).
2. Physicochemical principle: stone polishing machine has two polishing processes, namely "dry polishing" and "wet polishing". When the polishing stone is between "dry" and "wet", the stone products will have physical and chemical effects. When the surface temperature of stone increases, the concentration of polishing stone increases due to water evaporation, so as to achieve the strengthening effect. The gloss of the product starts to meet the ideal requirements, and the gloss reaches above 85 degrees.
The above is about the two working principles of stone polishing machine related knowledge, you must learn a lot from it, if you have doubts about the follow-up knowledge, we will provide answers for you!
