How to saw a stone at home

Technology description

The most suitable for home cutting (processing walls, floors and sinks) will be a compact saw. For production work, on the other hand, preference should be given to an overhead or multi-disc. A one-time rental of a cutting machine, which is equipped with a water cooling function and a diamond wheel will be acceptable. You can’t use the machine without cooling, or you could severely damage the stone.

It is forbidden to work without personal protective equipment. special goggles, gloves and headphones. Besides, it is necessary to have additional tools ready beforehand: sandpaper, diamond discs of different sizes, coolant, grinding wheel, dustpan and brush for cleaning. when preparing a diamond disc, it is necessary to check the flow of coolant to prevent overheating. the water must be directed straight to the rotating disc.

The fluid also provides additional protection for the marble texture.

The sawing line is marked with scotch tape or a special marker, after which the marble is secured in the cutting mechanism with the cooled wheel. It is the correct and accurate placement of the material that ensures the safety of the craftsman’s work. Slowly feed the tile to avoid overloading the machine. Do not drive the marble to the disc too fast, otherwise it may be completely destroyed or injure the craftsman. The panel is guided carefully forward until it is sawn through with the disc.

The surface formed as a result of sawing is smoothed with a diamond wheel with a small diameter or a sharpening stone. The integrity of the material depends on the smoothness and accuracy of the operator’s movements. Completes the work using sandpaper. you can use both dry and slightly moistened. It is recommended to start with 120th paper, gradually changing types up to 2500th.

This provides the smoothest possible sawing surface.

At the end the waste on all the marble edges is cleaned and the cooling water is removed. For beginners it is better to train on rough splinters before using the finish material. Particular attention should be paid to safety, including the grounding of electrical appliances. A more complicated method is marble sawing with the use of a metal cutter combined with a wire, which has a diamond coating. The complexity of the execution, as compared to conventional power tools, is in the independent and quite skillful arrangement of the coolant supply.

How to split a stone with wedges. Master Class

I will show you how to split huge boulders easily and evenly.

In this video, we use wedges to split large blocks of stone, these are pieces of old marble. Old stones often chip away at small stones no matter how evenly you try to split a large stone. But such a stone can still be chopped and used with wedges. During the splitting process there are always surprises be careful!

Do not drill shallow holes, such as half a drill bit.

The depth of the wedge hole is chosen according to the length of the wedge, not the petals. For example, for a 12 cm long wedge, with 6-7 cm petals, the holes should be drilled at least 12 cm deep. If the wedge is hammered in completely, it should not strike the stone.

Do not take the drill bit at random.

Diameter of the drill bit used to make a hole for the wedge in the stone should correspond to the diameter of the wedge.

Do not drive wedges into the stone wherever you have to, and along arcs and broken lines.

Do not make wedge holes in a straight line. Because we need flat stones for construction. And the flatter the sides of the stones, the better.

If you find it difficult to drill straight holes by eye, you can use a template with a straight board or a metal bar, depending on what you have at hand.

Don’t look for veins.

Practice shows that it is best to split the stones in the middle. I do not recommend looking for veins or cracks in the stone and trying to split it along its trajectory. Because the stone will probably split crooked.

Do not make the wedge holes too close together or too far apart.

The distance between two wedges should be 15-25 cm.

Don’t put wedges in the stone the wrong way round.

The ribs of the wedges should be inserted into the stone along a straight line, along the line of the split.

Do not drive wedges into the stone immediately and sharply.

The wedges should be driven in slowly, one at a time, gradually dipping them into the stone. And pausing for 2-3 to 5 seconds between each approach.

At this time the stone itself splits along the path you have set. So it is necessary to give him time to “think” and “take a breath of air”. Then you will hear a characteristic sound, the crackling of a stone.

Do not forget about the safety measures! Do not show weakness! Do not get distracted!

Use a pick, nail gun, hammer or crowbar to separate the broken pieces.

If you pick up the stone with your hands, do not release it, or release it very carefully so as not to pinch your extremities.

Keep an eye on the movements of the stones as you pull them apart. They can suddenly change their trajectory and crush you!

Do not be distracted by extraneous matters and conversations, be completely focused on your work and do not show weakness this will also greatly reduce the risk of injury.

Don’t miss the wedge and hit the rubber band.

Such blunders happen to beginners and experienced craftsmen alike. Kinks in the rubber band. Without rubber bands, of course, wedges can also be used, but they will be less convenient in the work and the time of work will be a bit delayed.

Sawing with diamond band saws

Diamond band saws are widely used in Japan and Germany. In Russia this trend is at the testing stage.

The length of the working circuit can be from 12 to 18 meters. As for the technological features of the process, the sawing machine is necessarily equipped with pulleys with a diameter of at least 1800 mm. This is to increase the life of the band and minimize band kinks.

If the thickness of the diamond band saw blade is reduced, the percentage of losses during machining can be decreased, as well as the power consumption and the consumption of diamond compound. But in order for the tool to remain sufficiently stable, not to produce defective products due to the saw’s withdrawal, it is recommended to tighten the band more or reduce the working speed.

Important! If the thickness is reduced by 0.2 mm the speed needs to be reduced by at least 20%.

Tensioning by means of a hydraulic cylinder. A pressure gauge is used to measure the value. The optimum tension varies between 40 and 50 kN (depending on band thickness).

The technological process of diamond band sawing is practically the same as diamond wire cutting.

Diamond band sawing consumes approx. 150 liters of water per minute.

Some machine models have an additional oscillating motion function, which increases productivity and improves operating conditions for diamond tools.

In the course of using the diamond band saw it is important to monitor the condition of the band saw at regular intervals. Routine inspection and maintenance of both the band itself and the diamond-coated elements is recommended for this.

To avoid excessive deformation of the body, you need to turn the band from time to time and make a repeated resoldering of its ends. You have to do it at least 3 times during the operational period.

Master-class on how to split rocks

Welcome to the Stone Blogging Project.

Today I will tell you about the workshop on splitting rocks, which we held for the second time within the framework of annual summer eco-camp on the Lake Chudskoe.

Last year we fully mastered the technique of splitting large rocks with wedges and demonstrated it to the audience. I must say it turned out very spectacular, interesting and each participant wanted to try to do it himself.

This year we have expanded the program and tested a new tool for splitting stones

Ecological camp is an event organized by the Ecocenter Natural House and Sergey Erofeev on Lake Chudskoe for those who want to learn the basics of building with natural materials, master classes and seminars by specialists in construction, landscape and agro-culture.

In the vicinity of Lake Chudskoe there are a lot of big boulders, cobblestones and stones, which in their natural state are not very suitable for construction. So, when they are removed from the fields, they are stored somewhere nearby so they don’t get in the way.

In this camp it was necessary to find a simple solution for the use of this natural material. This is what our master class on splitting stones was sharpened for.

The bottom line is very simple. If you learn how to split the stone so that it is not chaotic, but into planned pieces, this material could be used for local construction and development of the eco-center. post:

The published note got a great popularity on the Internet, they started to refer to it and post this information on different forums.

They started writing to me, consulting on the technology and asking where to buy these same wedges for the stone?

How to Cut Stone with Hand Tools | Ask This Old House

I will say at once that wedges for splitting stone, as it turned out, a scarce commodity. That is why there were many different attempts to replace them.

The most common is a sawn along the metal tube, which is inserted into a drilled hole and a chisel is hammered into it.

But I wanted to find a more beautiful solution. That’s what the eco-camp did, and also held a master class for those who wanted to.

Rock processing equipment

For those craftsmen who plan to do quite a lot of stone processing, it makes sense to consider special equipment. Machines are divided into two big groups. disk and wire. The latter are large in size, as they are used in industry to cut huge blocks of stone. Therefore, this option for the home (workshop) is not suitable.

The disk equipment is optimal for home processing of natural material, but not many people think such an expensive purchase is successful and justified, especially if the masters are not planning to do this kind of work constantly. However, such a machine can replace a simple angle grinder with a diamond disc. The circular saw is a second worthy candidate. There are three types that can be used for cutting stone.

  • Hand saw. It is a compact, but not the best solution, as it requires a lot of effort. The use of such a tool is justified in the case when you need to produce 1-2 large objects.
  • Equipment powered by diesel fuel and electric saw. Both models promise a higher speed of work, but in this case the skills of handling the tool are important. Otherwise any careless movement will lead to damage to the material or to injury to its owner.

Since the need for such processing occurs more often from time to time, it is more logical to do with the usual tools. If the activity seems extremely interesting, you can consider buying special equipment.

The cost of cutting of natural stone

In this section, we will try to describe the cost of these works and understand how profitable they are. The profitability of such production can be calculated by a simple formula, which looks like this:

  • RP. profitability of production itself.
  • The estimated income you expect to receive.
  • The production costs of cutting stone (purchase of material, depreciation of the machine, electrics, etc. п.).

It is also advisable to calculate the one-time cost of the initial purchase of equipment and materials: the price of equipment and the price of materials Po Pm. In the end, you only have to add the added value for the work and get a net profit.

Home repair

For those who will self-cut porcelain tile at home, it is worth saying that it is not that difficult. It is necessary to know some features of this work, to which we will pay attention below, and not to be afraid to take up a new business for yourself.

To cut porcelain tile without chipping you need to make a marking of the cutting lines with a carbide scroll or glass cutter. It is necessary to run this tool several times along the future cutting line. You will notice that on this line there is already a chipping of the upper layer of porcelain stoneware, but the width of this chipping is very small.

Make the cut so that the cutting edge of the cutting wheel is close to this line with its side and the entire width of the cut is shifted to the side that you don’t need now. If the disc on the angle grinder is good, then additional chips are unlikely to form. you will get an almost perfect cut.

While cutting, the tile vibrates, so it must be secured. It is best if the substrate under the tile will be non-hard materials that will dampen this vibration. Styrofoam or foam board of medium or high density is ideal.

How to cut the artificial stone?

Artificial stone has gained widespread popularity and popularity around the world. And all because it looks similar to the natural, but it is cheaper and has greater strength. The artificial stone is used for registration of a house interior (most often in kitchens and bathrooms) and arrangement of garden paths. Many are interested in the question: what can cut the artificial stone, and now we will try to answer it.

Artificial stone is made of materials of different hardness, and the technology of manufacture is used far from the only. Depending on the varieties of stone, a cutting method is chosen.

  • Agglomerate consists of large pieces of quartz, granite, lime and marble, which are combined with polyester resin, which makes the stone very durable.
  • Stone on a concrete base is similar to concrete, as it consists of sand and cement (sometimes gypsum is added instead of cement). Cheaper than agglomerate, but less durable, resilient to moisture and low temperatures.
  • Porcelain stoneware is made of pressed kaolin clay, so it is very hard and durable.
  • Acrylic stone is made of a fine-grained filler impregnated with acrylic resin. Plastic when heated, amenable to high temperatures and scratches.
