As the processing of precious stones ?Types of cut
You will need:
  • stone,
  • vise,
  • sandpaper,
  • diamond saws,
  • paste GOI,
  • felt.

Despite the fact that working with stone is complex and requires not only physical strength, but also professional tools, it can be performed at home.It begins processing stones always with a thorough cleaning that has accumulated over many years on the surface of the stones.As a rule, to begin hewing produced water, brushes, scrapers, and varying degrees of aggressive detergents.This helps to remove the primary coating of dirt and to remove plaque lime stone and calcite used in more serious compounds such as hydrochloric acid or oxalic acid.Each stone is unique, because the nature of this work and it is important for any of them to select the proper approach.

Treatment should show the natural beauty of the stone, sometimes it is necessary to cut it for a long time, or polishing.Deciding on a cutting especially easy, because often the stones are completely closed, and it is impossible to guess at wh

at angle within the pattern will be more profitable.These skills come only with experience, but carefully handle the stone can be learned much earlier.How should be treated with a stone, it is determined primarily by its hardness, toughness, fragility and heterogeneity of the properties.The most heterogeneous mineral - mica, so its treatment is different in different directions.Stone working at home may include cutting, turning, grinding, polishing and the threads on the stone.Cut stone most diamond thin disk, as the edge of the cutting tool must be harder than the mineral.

You can also cut the stone and soft metals, with the condition if the incision site to be fed with water dissolved abrasive.But the diamond saw many times accelerate the process and minimize the loss of sawn stone.To prevent cracking of the stone in the process of heat caused by friction, coolants are used.In airtight industrial machines used kerosene, but at home he is flammable and easier instead to take water with dissolved in it with soda.If you have the ability and desire, the house can be assembled miniature cutting machine stone, but you can also use diamond saws or saw-grinder.For security reasons you must wear a face mask and goggles when working, and the room ventilated.

stone to be treated firmly clamped in a vice on a table or other suitable master surface.To prevent damage to the worktop, reduce the need for the substrate, then firmly tighten the vise, as loosely mounted stone can damage the instrument.The capacity of the water to be in close proximity to wash away the appearance of dirt and cool stone.Files on the stone is held pre-groove, after which it begins sawing.Sometimes one stone requires several incisions, and is first necessary to decide how to implement them at the lowest cost.The hardest stone sawing along, making a flat cabochons.When before the end of the work is a little bit, you need to exercise the greatest care not to break off stone.

# 5

It often happens that in the last millimeters of work jammed saw blade, especially for manual processing.To break the awkward movement is not a stone, you need to carefully pull it out of the clutches and the same careful movements to free nail file.To avoid this situation, you can cut alternately from the two sides to the middle, so less likely to break off a corner and break the unfinished work.Stripping sections also requires a lot of time and effort for this work will need to sandpaper the coarsest fraction.She cut up process until disappears deepest scratches and dents.If necessary, the same paper is smoothed by side, and the opposite side of the processed stone.Working with sandpaper also requires constant wet stone, and sometimes carried out directly in the water tank.

# 6

After large scratches and bumps are smoothed using coarse sandpaper, a stone with a soft cloth and examined for smaller irregularities and chips.Such roughness require processing finer sandpaper, then clean the stone again, rubbed with a soft cloth and examined in good light to detect small defects.Using whenever finer sandpaper until my best, you need to fully align the stone, leaving no scratches on it, rough edges, dents and bumps.Sandpaper zero numbers polishes the stone, giving it shine.Before the final polishing is required to check the stone very carefully, because the cracks and scratches can become clogged paste GOI, spoiling the entire result.Final polishing is done or felt.

# 7

quickly and conveniently using a polishing machine with a rotating shaft, which is squeezed out a small amount of paste GOI.Stone for some time pivots with respect to machine different sides and polishing occurs relatively quickly.Manual work is done in the same way, but the time will be spent much more, as the polished stone manually too convenient.You can also fix the polishing stone still, and keep a job using a drill or screwdriver with an appropriate device.This milestone is called polishing or glossing, and it is necessary for self-treatment of stone.Polishing closes the existing micro, under which the stone is destroyed faster.
