Tricks to cut granite
How to cut with a radial granite and ceramic materials without chipping the edges
There are many occasions when when installing granite pieces or porcelain or ceramic materials, stone fitters are forced to have to make an adjustment in the dimensions of the pieces in situ, at the foot of the pit, using as a cutting tool a radial machine or grinder, something also very common in the workshops dedicated to the eleboration of stone or derivatives of quartz or ceramic materials, where you have to perform manual work on the pieces to achieve the desired finish.
The difficulty of this type of manual work is quite high, taking into account the very nature of the materials, granite is a very resistant material with a high coefficient of resistance to cutting, and in many of its varieties it can be prone to the appearance of the dreaded “esportillos”.
Ceramic materials may be easier to cut, from the point of view of the opposition they exert to the cut, but they are materials with a high susceptibility to chipping the edges where the cutting is carried out, requiring the use of specific discs for these materials
That is why to obtain clean cuts, well executed, free of esportillos are necessary a series of skills and specific tools:
The first thing that should be highlighted would be the use of our own intelligence or common sense. A setter can receive criticism of their work of various kinds. What we must ensure is that these criticisms focus on issues of taste, choice of material, color … and not for reasons of poor execution. To avoid these uncomfortable situations, apart from our experience in the execution of these works, you must have adequate machinery and of course a good diamond blade.
To make this possible, from Maser we recommend Tyrolit brand discs, discs that allow clean and straight cuts to be made, free of esportillos, both in granite and in porcelain materials, working dry by using a radial machine. Our extensive experience in the use of these discs, leaves no doubt, they are the best cut, do not cause splinters and their useful life is very long.
Granite diamond blades for 125mm diameter manual cutters and Tyrolit’s 115cm diameter porcelain materials diamond blades are in the highest category in the world of stone cutting discs. In addition, Tyrolit products are manufactured under European safety regulations EN13236.
To prolong the life of these discs, it is advisable to follow a series of recommendations that we remember below
- Use the appropriate disc for each work piece. For this we must make sure in the leaflet or packaging of the disc, which is the appropriate material for its use.
- During the use of the disc, it is convenient to keep it in an upright position.Regulate the advancing force that we carry out while performing the cutting works, looking for the more suitable depending on the material that is cut.
- Always make oscillating cuts.
- With this we will be able to cool the tool and avoid overloading the disc.
- Make cooling cuts after prolonged cuts, to avoid overheating the disc.
- Do not make curved or sharp cuts.
- Do not subject the discs to shock, heat or force them with tools .
- Do not use the disc for grinding frontal grinding of the stone pieces (Do not exert lateral pressure on the disc)
- Tyrolit discs regenerate the diamond during cutting. The lack of performance in the cut, and a curved aspect of the edges of the segments are the evidence that the disc is getting embossed.
- To solve it we must make small cuts with an abrasive material (bricks, asphalt, concrete …) or with a Tyrolit fan plate. With this, the diamond blade is reaffirmed, recovering all the original properties.
- The appearance of sparks during the cut is normal in hard materials with iron and stone content, and no danger is involved. We will discard all those used or defective tools, always having take into account local and national regulations and regulations
Thus, with our common sense together with Tyrolit dry cutting discs, for granite and porcelain materials, and these little tricks, performing a perfect and clean execution in the cutting jobs for a setter is much simpler.
This will add not to neglect the safety at any time, so remember that when we are using this type of tools the following considerations must be met (we always find them in the packaging of Tyrolit discs, whose concern for the efficiency and quality of the Materials that it manufactures are only matched by the concern for the safety and health of those who will use them.)
- Do not use for frontal grinding
- Do not use if damaged
- Do not cut with one hand
- Always read the instructions carefully before use
- Use visual audio protection
- Use gloves
- Use respiratory protection
And is that MASER not only worries about being able to provide you with the best tools and machines in the stone sector, but that we put health and safety before other considerations.
