manual stone polishing machine

The polishing machine is divided into automatic polishing machine and manual stone polishing machine. Today we will introduce manual stone polishing machine.

manual stone polishing machine applications are: metal tools, zinc and aluminum castings, commemorative coins, furniture, clothing and bag hardware, locks, jewelry and powder metallurgy and other metal polishing; needle for stainless steel, iron, copper, zinc, aluminum, magnesium alloys and other materials surface polishing, removal of edge, chamfering, rust (oxide), Coarse polishing, precision polishing, gloss and polishing.

In the process of grinding and polishing, whether the desired results can be achieved depends mainly on the four factors such as the correct selection of lapping machine, grinding stone, abrasive agent and reasonable grinding process. Therefore, it is very important to choose good grinding machinery, grinding stone, abrasive agent and formulate reasonable grinding process plan.

plastic grinding stone: generally used in soft or non-ferrous metal materials such as gold, silver, copper, acrylic, plastic products, etc.

ceramic grinding stone: this kind of abrasive stone has strong grinding force, which is suitable for grinding burr, oxide skin and chamfering of ferrous metal.

porcelain grinding stone: Porcelain grinding stone almost no grinding force, for all metal or plastic workpiece polishing and mirror treatment.

special grinding media: carbon steel and stainless steel are generally used as materials without grinding force, mainly used for polishing metal parts.

soft abrasive medium: the soft grinding medium is mainly made of walnut shell, wood bar, bamboo grain, corn core and plastic grain, and it has no grinding force and is used for dry polishing.

Abrasives main functions: lubrication and balance, reducing the wear and tear of grinding stone; softening the oxide skin on the surface of the workpiece; removing oil and cleaning the workpiece; antirust and luster; enhancing the efficiency of grinding and polishing;

material: depending on the material of the work piece. Such as gold, silver, stainless steel, copper or other metals, to choose the right abrasive

fineness: according to the quality requirements of the workpiece, such as rough grinding, fine grinding, polishing and so on. Different surfaces require different kinds of abrasives.

Particle grinding: when the abrasive particles are grinded from coarse to fine grinding and polished, the trace of grinding on the surface of the stone is from coarse to fine to no naked eye. The surface is smooth, smooth and delicate. When the depth is 110 microns, the surface appears mirror gloss, bright color and bright color.

Physical and chemical principle: the process of polishing is 2, that is "dry polishing and wet polishing". The polished millstone has physical and chemical effects between "dry and wet" between "dry and wet". Dry polishing is the evaporation of water on the surface temperature of the stone, resulting in the increase of the concentration of polished grindstone, so as to achieve the strengthening effect, the glossiness of the product begins to reach the beginning. To the ideal requirement, the gloss is above 85 degrees or higher.

manual stone polishing machine

manual stone polishing machine is polished on the processed product. After the polishing product is scald, the surface is added to the surface with water to play a cooling effect, not to allow continuous water or a large amount of water. Otherwise, the lubrication of the water will not achieve the ideal effect, and can not all use dry polishing. Too high temperature will burn the surface of the plate, and will burn out the surface of the plate. Make a crack in the surface of the plate.

Generally speaking, after the product is fine grinding, the glossiness of the product is about 40~50, and some stone can not reach the gloss of the above, such as Shanxi black, black gold sand, Jining black and so on. The gloss of this kind of product is only 20~30 degree after fine grinding. With the humidity, the temperature rise, the cooling, the polishing process, the physical and chemical reaction, the product in the "dry polishing, wet polishing", glossiness increases gradually, glossiness reaches more than 85 degrees.

(1) coarse grinding: it is required that the grinding tools have a deep cutting tool, high grinding efficiency, coarse grinding lines and rough surface, which mainly remove the trace of the saw blade in the front process, and grind the surface of the product into place;

(2) semi fine grinding: remove coarse grind marks and form a new finer texture. The machined surface is smooth and smooth;

(3) fine grinding: fine grind after the product pattern, particle, color has been clearly displayed, the surface is fine, smooth, beginning to have weak glossiness;

(4) fine grinding: processed products without naked eye detection. The surface is more and more smooth, gloss is about 40~50 degrees;

(5) polishing: the surface is as bright as a mirror and has a certain gloss (above 85 degree).
