Drilling artificial stone is best with the help of a bora, at the end of which there are attacks of solid alloy. In construction, such borants are used when drilling concrete. In order for the work to be more productive, drilling is performed. Drilling with a perforator occurs due to drill drill.
For drilling artificial stone, perforator and small drills with diamond spraying.
The car is almost not heated, and the drilling of the holes is produced much faster.
Artificial stone can be drilled with a drill with diamond spraying. Here you can use a conventional electric drill. If you need to drill a thin hole, for example, in a small natural stone for decoration, an needle with a diamond tip is used. It is done on a boring machine.
If a large diameter hole is required, an artificial drill is drilled by a crown. Crown, like a bur, has a hard alloy attack. In construction, such a drilling is made in carrier concrete walls. This is done in the case when plumbing or ventilation pipes should be paved. Drill the material with a crown, which has a large diameter, it is necessary only on small revs. During drilling on carbide attacks, crowns are necessarily filed cold water. It is necessary, in order for the attacks not overheat. Otherwise, they will fail before the deadline.
The main tool for drilling stone is:
In the event that you need to drill a large diameter hole in stones, special equipment is applied. So, in order to drill them under communication pipes, such equipment is attached to monolithic concrete Wall. In order for the stone to be damaged by the working surface of the crown, cold water is supplied to it with hoses.
The processing of solid materials is related to the use of a certain technology. The drilling of stones has its own specifics. For example, granite is very solid and at the same time a very fragile stone. When you select the rotation of the tool, you need to proceed from the diameter of the drilled hole. The larger diameter you need a hole, the smaller speed is required.
To open the hole in the right place, you need to make a small groove tilting the rotating drill to the side.
During drilling, water supply must be mandatory. Water, firstly, protects the cutting edges of the diamond drill from overheating, and, secondly, shears the sludge. Before the start of drilling, in order for the hole to work in the right place, it is necessary to tilt the rotating drill to make a small groove. After that, the drill is leveled, and even drilling begins in this place. It is necessary that at the very beginning the drill does not come from a given point.
In order to avoid damage to the edges of the hole, the drill must be well centered. The drilling object must be on a flat surface and be well fixed. Unlike concrete, drilling granite in perforation mode is undesirable. It is very fragile and in shock mode can split.
When drilling granite should proceed from the following parameters The diameter of the opening and speed of rotation of the drill. With the diameter of the hole - 6 mm, the speed of rotation should be - 2000 rpm. When the hole is 12 mm, the speed of rotation is 950 rpm. If the opening is 24mm, the rotational speed should not exceed 700 rpm. Such data is obtained by experienced and are the most optimal.
In some cases, granite must be reinforced. This necessity arises when a tabletop is made from a relatively thin sheet of granite. Large cargo on the surface of the table can break it. To increase the strength of the granite slab, it is enhanced by a steel rod.
On the inner surface of the plate with the help of a grinder and diamond circle, a smooth groove is made. Depth and width of the groove must be 1 mm more than steel rod. After removing the dust from the groove, the steel rod is placed in it. The rod laced in the groove is poured superclaim. After the glue is freezing, the strength of granite reinforced plate will be increased several times. It is also established by experimentally.
Due to the beauty of the drawing, a variety of colors and its durability, this natural material It is very in demand in high-end buildings, as well as in the projects of reconstruction of old buildings. Therefore, the issue of processing natural stoneIncluding the drilling of granite, is relevant during construction and repair work.
The drilling of natural stone requires knowledge, skills in work and a special tool. Incorrectly chosen drill or violation of the work technology most often leads to at least the spoiled drills, and in the worst case - to the cracked material.
Before starting drilling granite, think well and answer questions:
Works related to the drilling of granite should be carried out very carefully, without a rush and only after accurate verified markup. This requires comply with certain rules for the implementation of such works. Fix and redo the error will be very difficult or impossible at all.
Drilling crown with diamond coating.
The speed of rotation of the drill or crown must be minimal and selected depending on the diameter of the tool. The larger the diameter, the less should be the number of turns of the drill. For example, with a diameter of the drill 12 mm, the maximum allowable rotation speed is 950 rpm, and at 20 mm - 700 rpm.
It is necessary to feed water to the drilling site, which will cool the cutting tool and wash the slag formed during operation. The use of water protects the drill from the jamming and increases its life. In addition, the water will cool granite, as a result of which the edges of the opening will be smooth and neat.
The stone that must be drilled must be pressed to a smooth surface. For its reliable fixing, it is necessary to use clamps or other clamping devices. No part should be on the weight.
Before you start drilling, make markup. To do this, turn on the surface paper malarious tape to the surface, draw the contours of the hole and its center. Scotch will not give the drill to go away and leave scratches on the surface of the stone outside the opening.
If you have never performed such a job before, try to drill the hole in the unnecessary fragment of the stone. If the trial attempt was successful, then this fragment can be used as a guide template. To do this, secure it with the clamp at the drilling site and direct the cutting tool on the template. There will be no drill to slide, and the water supply will become easier if you pour it inside.
For drilling natural stone It is necessary to use a drill with the possibility of changing the speed of rotation. It is best to use a diameter diameter diameter for the cutting tool. In addition, it is necessary to prepare 2-3 clamps, a greasy paper tape, a marker and water in a plastic bottle with a hole.
Install the granite workpiece on smooth surface And reliably fix it with the help of clamps, and so that the clamps do not scratch the polished stone, to put wooden planks for them. Stick paper tape to drilling location and make a markup with the application of the center and the opening circuit.
Scratch the drill or tank the center mark in order to be able to start drilling from this point.
Secure the diamond crown into the electric drill and install the central guide to the scratched center of the hole. If the crown design guide is not provided, then make a template for the necessary diameter of a wooden plank, secure it on the surface, and use as a guide during operation.
Create drilling on small revolutions corresponding to the diameter of the applied cutting tool. The larger the diameter, the less the crown revolutions should be. Regularly water water from a bottle of a diamond crown for cooling it and lubrication.
Do not press too much on the drill during operation, as this may lead to a premature split of granite. The process should continue until the crown passes the entire stove thickness. Only after that you can remove the crown of the hole.
In addition to the diamond cutting tool, you can use winner drills, diamond dust or corundum to get holes. These ways are less effective and longer, but also allow you to achieve the desired result.
The drilling of the holes in granite with the help of a winning drill is performed at high speed of rotation and constant water supply. If the process begins to slow down, the drill must be removed and dotted. To obtain a hole in a granite using corundum, diamond dust or a hammer to win, a copper or brass tube will need to be consolidated in a drill. On the granite surface, around the diameter of the opening of the opening, make a side of plasticine or quick-drying spacure with a height of 4-5 mm.
Pour the abrasive material inside the fence and drill with a tube with the smallest turns of the drill. During work, do not forget to periodically pour water to cool.
Granite drilling is a rather complicated work that requires skills and accuracy. However, if there is required tool and attentive attitude to execution, any house master Can perform it yourself. And it will be not bad if you, before drilling, practice on unnecessary trimming.
The best tool for the drilling of granite is diamond crowns. Only their application will allow you to get a hole of the perfect quality, without applying excessive effort.
Today we will talk about how they own at home to drill a hole in any natural or artificial stone with their own hands. We also consider the techniques and technology of drilling stones or how and how to drill stones
How to drill a hole in the stone yourself and which tool is necessary for this?
The drills are now on sale - crowns with diamond spraying and they can be purchased in almost any large construction market. The price depends on the thickness of the spraying and time of the drill service.
And if you need to drill one hole and two, then almost anyone will suit. And if you are planning a frequent use of such a tool, it is best to purchase a crown, in which the diamond is not sprayed, and is pressed throughout the volume of the cutting edge.
The fastening of the crown is also different. You can use a drill or "Bulgarian". We use heavy cutting machine and device for drilling holes in stone products, they have the same fastening as on a small cutting machine.
And now you have become the owner of a drill with a diamond spraying, what to do next?.
How to drill a hole in the stone to be smooth and neat?
I think that 4 simple steps Will guarantee you long service Diamond crowns when drilling holes.
Step 1. Diamond drills When drilling holes in the stone use at low speeds (revs). Small drills with diamond spraying should be used approximately 1-2 speeds of your instrument - this is from about 700 to 1000 revolutions per minute.
Diamond drills should be used at variable speeds depending on their diameter.
6mm - 2000 rpm.
12mm - 950 rpm.
24 mm - 700 rpm.
Step 2.
Drill holes in stone and other materials needed with water. Water prevents overheating the cutting edge of the diamond drill, flushes sludge from his pores. This in turn will extend the service life of the drill, will fight it from the encoding, as well as the stone itself will not overheat and the edge will remain neat.
In production, when drilling holes in stone, water is supplied automatically into the inner part of the drill under pressure and the drill is constantly washed with water. At home, this is not always done.
To do this, you can make a "bath" around the drilled hole. You can cut out the middle part from the plastic bottle and glue it with a stoneware surface, fill it with water. With the drilling of the holes, lift the crown so that the water wet the cutting edge and got into the drilled hole.
Step 3.
If you have little experience before proceeding to drill holes in a stone, practice on any trimming.
Make marking. Apply a line on a stone. Often, a pencil polishing practically does not leave marks, so you can apply a greasy paper tape and make the necessary labels on it.
The first way, which is often recommended when drilling holes in stone.
First, start drilling the stone at a significant angle to drill a small groove, then gradually align the crown, to the vertical position, continuing to put it much. If you immediately press the diamond crown to the surface of the stone and start drilling, then the drill will not stand still and will "ride" over the surface and spoil polishing.
Not always the drills are well hotzed and if you have a poor experience in the drilling of holes in the stone, it is originally possible not to keep the tool and turn the polishing, break the edge of the resulting hole, and finally just inaccurate drill.
There is a fairly simple second way to accurately drill holes.
To do this, you can drill a hole in any trimming of the stone, you can say to stretch.
After the hole is drilled and fully prepared, it can be used as a template. Just it simply applied to the product in which you need to drill a hole and adast. Thus, the drill will move along the already drilled hole, it will not beat it and in your product will be neatly drilled hole. There you can also pour and water.
Step 4.
I already mentioned it, but still decided to allocate in a separate column.
Do not press the crown while drilling holes. Diamond spraying crowns are very sensitive to pressure and overheating. Periodically raise it so that it is wetted with water and cooled.
Granite is a material that is the hardest handle. It is very solid, but at the same time a rather fragile stone. Therefore, work related to drilling holes in granite should be carried out very carefully and neatly. In order for the granite stone during drilling to be split, it is very important to comply with a number of non-good rules.
It is necessary to drill granite with water, as it prevents overheating of the cutting edges of diamonds, and it will also wash the sludge from his pores. When drilling a granite with water, you, therefore, slightly extend the use of the drill and projected it from the jam. Also, granite when drilling will not be too hot and the edges of the opening will be clear and neat. Currently, in production during drilling holes in stones, water is fed under pressure automatically to constantly wash the drill.
If you previously never performed the drilling of granite, then before you begin, practice on some fragment or trimming. Because to start drilling granite, make a markup, applying a line to the surface. It is best to make it the best paper painter scotch, since a simple pencil does not often leave the slightest trail on polishing.
How to drill granite, the first method: start drilling granite at a small angle, so that a small groove first drilled. And then smoothly align the crown to the vertical position. If this is not done, then the drill will "ride on the surface."
Granite drilling, the second method: In practice, there are often cases that drills are bad or not enough for accurately centered. And if you have no drilling experience, you can not spoil the granite polishing, damage the edge of the hole or inaccurately drill it. Therefore, the second way is that you overcome first the same hole on a small trimming of granite. And if you have come successful, you can now apply it as a template. To do this, it is necessary to simply apply it to the desired area of \u200b\u200bgranite and adast. Now the drill will not ride on the surface. There will also need to serve water.
How to drill a hole in granite, step-by-step instruction.
To drill a hole in the granite you will need an electric drill in which you can adjust the number of revolutions. You will also need diamond crown for diameter, copper tube Or winning glass, water, half-rounded form, and maybe you will need a diamond dust or win.
Before proceeding with drilling, install the granite workpiece as convenient and fix it. Granite stone must completely lie on a flat and flat surface.
Scratch the metal drill center of the alleged hole. it important momentthat will not give the drill to slide on the surface of the granite during operation.
Fix the crown of the desired diameter in the electric crown. It should be covered with diamond spraying. Otherwise, you will not be able to drill the hole.
Drill a hole in granite only on low revs and in no case turn the perforation mode. Failure to comply with this condition can provoke a split of granite or cracks.
During the entire process of drilling a granite into a hole that drill, regularly pour water. This can be done using the usual plastic bottlein which you first need to drill the hole. Perfect optionWhen you attract a second person to join the water so that you can fully focus only on the drilling of granite. It is very important that the drill "not swimming" in the liquid.
Why it is necessary to use water when drilling granite:
· You will not apply unnecessary efforts to drill;
· You will save the drill for subsequent work, extended its life
· You thus relieve granite from overheating.
How to drill granite if there is no diamond crown.
If you do not have a diamond crown, you can get out of the position like this: Make around the circumference of the alleged opening of the plane ring. Its height should be three or five millimeters. Its inside it must be filled with a small amount of corundum, diamond dust or wins. The drill need to fix a small tube of copper or any other non-ferrous metal, such as brass. After that, you can proceed to drilling on small revolutions and without perforation. Do not forget during operation to carry out water, which in this situation will cool the tube.
And if you have no diamond crown, and a non-ferrous metal tube, you can try to drill granite with a winning drill. But only in this situation the drilling must be carried out immediately on large circulation, constantly feeding water. As soon as you feel that the drilling does not happen, immediately take the drill and pumped it with a semicircular noodle.
Approves must be made with extreme caution so that the cutting teeth in no case are overheated. Otherwise, they will immediately become soft, and even more quick speed will be blown off. It is noted that during the drilling of the granite, the drill from winning the drainage must be made every 20-40 seconds of drilling.
As can be seen, the drilling of granite is not easy, as it requires certain skills, knowledge and skills. So, starting to work, be sure to practice trimming of granite, and only after that you will be able to go!
