When it comes to stone polishing machines, I believe that everyone does not know what it is coming from, and they will feel unfamiliar with this equipment. So, what exactly is a stone polishing machine? In fact, the stone polishing machine is a kind of stone machinery equipment that uses mechanical equipment to quickly run and "dry polishing, wet polishing" to achieve the polishing effect. So, let me introduce to you the working principle of stone polishing machines and the knowledge content of influencing factors.
Here is the content list:
l Introduction to the working principle of stone polishing machine
l What is the main process reflected in the principle of particle grinding of stone polishing machine?
l What are the factors affecting the work of stone polishing machine?
Particle grinding: When the abrasive particles change from coarse grinding to fine grinding and polishing by the stone polishing machines, the grinding marks on the stone surface change from coarse to fine to no visible marks, and the surface of the stone polishing machine becomes smooth, flat and smooth. Delicate, when the depth reaches 110 microns, the processed surface appears mirror-like luster, brilliance, and bright color.
Physical and chemical principles: There are two polishing processes for the stone polishing machine, namely "dry polishing and wet polishing". When the polishing stone is between "dry and wet", when the stone product has physical and chemical effects, dry polishing is the increase in the surface temperature of the stone. High evaporates the water and causes the concentration of the polishing grindstone to increase, so that the stone polishing machine achieves the strengthening effect, and the gloss of the product reaches the ideal requirement, and the gloss is above 85 degrees or higher.
The polishing grindstone is polished by the stone polishing machines on the processed product. After the polished product is hot, add water to the surface of the board to cool down. Continuous or large amounts of water are not allowed. Otherwise, the lubricating effect of water will make the polishing If the desired effect is not achieved, dry polishing cannot be used completely. Excessive temperature will burn the board surface and cause cracks on the board surface.
Particle grinding consists of the following processes:
l Rough grinding: The stone polishing machine is required to have deep tooling, high grinding efficiency, coarse grinding lines, and rough surface. It is mainly used to remove the saw blade traces left by the product in the previous process. Grind the product's flatness and modeling surface in place;
l Semi-fine grinding: remove the rough grinding traces of the stone polishing machines to form new finer lines, and the product surface is smooth and smooth;
l Fine grinding: The pattern, particle and color of the product after fine grinding by the stone polishing machine have been clearly displayed, the surface is fine and smooth, and there is a weak gloss;
l Fine grinding: The product processed by the stone polishing machine has no traces that can be noticed by the naked eye. The surface is getting smoother and the gloss is about 40~50 degrees;
l Polishing: The surface of the stone polishing machine is as bright as a mirror, with a certain degree of mirror gloss (above 85 degrees).
Generally speaking, the gloss of the product is about 40~50 after being finely ground by the stone polishing machine, and some stones cannot reach the above glossiness after being finely ground, such as Shanxi black, black gold sand, Jining black, etc. The gloss of the product after fine grinding is only between 20 and 30 degrees. It is not enough to explain the principle of the previous particle grinding. This kind of product is polished in the stone polishing machine "dry and wet". The temperature rises and decreases, and the stone polishing is strengthened. During the polishing process of the machine, a physical and chemical reaction occurs, and the gloss of the product is gradually improved during the "dry polishing and wet polishing" of the stone polishing machine, and the gloss is over 85 degrees.
l The type of stone polishing machine polishing agent: Although polishing agent is a special polishing material, the difference between it and the grinding material is mainly in the processing mechanism of the stone polishing machine. In principle, some low-hardness micropowder materials can also be used as polishing agents. But generally, high-hardness polishing agents are better than low-hardness ones and have a wide range of applications.
l Stone polishing machine polishing fluid: water is a commonly used polishing fluid. It can not only play the role of grinding and cooling, but also as a medium for physical and chemical effects in the polishing process. If the stone is polished by the grinding action of the stone polishing machine, such as diamond powder, the polishing liquid generally uses oily organic liquids, such as sewing machine oil. Its cooling, lubricating and dispersing effects are excellent.
l Stone polishing machine polishing disk: a flat stone polished panel, which is a form of expression and processing of stone surface grinding. Hard disks made of metal materials are often used as polishing disks. The polished surface of the floppy disk polished by the stone polishing machine is easy to yield into a concave surface when the stone is pressed, which is suitable for camber polishing. The medium hard disk has good abrasion resistance, good adsorption, and certain elasticity, and it has a good polishing effect on flat stone.
What is more? Apart from stone machinery products, out company also provide customers with various kinds of high-quality diamond tools.
