Stone abrasive polishing technology introduction

Abrasive polishing stone grinding and polishing the stone introduced types of technology; with synthetic diamond powder , silicon carbide powder and corundum abrasives such as

bulk, and then mixed with a liquid or ointment polishing suspension or a polishing paste as a polishing agent, with the appropriate devices added to grind

Polishing tool or workpiece. This technique is bulk abrasive polishing techniques. Different abrasive materials to meet different abrasive. Such as the use of diamond

abrasives are best to use tinned abrasive, but when you use silicon carbide abrasive abrasive gray cast iron. However, due to grinding

Material metering device to use artificial or added to the workpiece, so abrasive unevenly distributed and require operation by skilled craftsmen in order to achieve

high quality standards. The use of polishing grinding technology can avoid the recurrence of such situations: Abrasive distribution, polishing quality

Good and stable quality, easy to implement continuous operation, high polishing efficiency, general polishing time than with a 30% reduction of bulk diamond abrasives.

This polishing grinding technology, using bonded abrasive, that diamond, silicon carbide or corundum powder for abrasive and binder to burn

Knot, made of plated or bonded grinding block technology. Fixed to the upper millstone made of polished grinding. Small grinding blocks for general use materials such

as asphalt or sulfur bonding, large grinding block is connected to the disc with a dovetail groove on. Stone polishing abrasive grinding stone substance described in

terms of human

Or mechanical force, the rotation of the disc perpendicular to continuously feed stone, in the contact region between the friction, wear, uneven surface layer of the

sheet surface is gradually polished. Because granite rocks generally hard, abrasive hardness must be more than a hard stone

Degrees. Generally abrasive to be used to complete the six sets of grinding, polishing process. The first two grinding force to be positioned grinding, from the

leveling and controlling the thickness of a sheet; respectively behind coarse grinding, fine grinding, polishing and other processes. Depending on the diameter

Size, grinding block shape, number and arrangement techniques, the binder and the abrasive grit size of different grinding head has a different structure. Grinding

diameter of 4 to 12 inch many, the most commonly used is 10 inches. Grinding block shape straight bar, oblong, umbrella, ring

Shaped, straight bars and oblong most common. Grinding diameter grinding blocks depending on the number and size of the grinding blocks, from a few blocks to the ten

blocks. Grinding blocks arranged radially technology is the most common, but there are also arranged according to spiral technology. The abrasive binder metal binder

, The resin binder, magnesite and polymers. The manufacturers use different grit size range. The diamond abrasive, from the coarse grinding to polishing using 30 mesh

grinding a few μm are used. 2. Affect the quality of the stone grinding and polishing stone many varieties of factors

, Its physical properties, chemical composition, grain weight, and mineral crystals and so on polishing composition differences affected the quality. As the stone

different from the crystalline, non-uniform when the polishing surface. Larger grain stone, polishing unevenness smaller than the grain size of the stone

Obvious, so small grains than large grain stone polishing stone easy. Polishing grinding feed rate on the polishing quality great impact study showed that with

polishing grinding feed rate, the stone surface gloss will decline, but it will speed up the feed rate is too low grinding mill

Loss and reduces production efficiency. Polishing and grinding running technique to rough grinding, fine grinding technology with the grinding operation performed.

Grinding operation technology with horizontal and vertical extent of the density of the points. Stone abrasive polishing technology introduction
