Diamond blades consist of two fundamental elements: a steel hull and a diamond cutting edge. The latter can be three types: segmental, continuous or serrated. The housing is made of high-quality drive, heat-treated hardened steel. The segments are separated by flushing grooves (slots), which allows you to drive cool during cutting due to the fact that water flows between the segments (when wet cutting) or the air passes (for dry cutting). They also allow the cutting disc to flex slightly during the cutting process.
The segments contain a mixture of diamonds and metal powder. During the manufacturing process of metal powder and diamond mixture was compressed at a very high temperature, thereby forming a solid metal alloy retaining diamonds. The disc enters into the material without the steel rubbing against the body as a segment or slightly wider than its edge.
How does the diamond blade?
- Diamond blades are not cuts, and grinds. In the process performed in the production of single crystals of diamond grinding on the right and left side surfaces of the segment, whereby the grinding material to be cut is made. Metal grille holds each diamond in place. In the process, every diamond is supported " tail ", comet strengthen existing lattice directly " behind " diamond crystals.
- Placed in such a way to penetrate diamonds in the material, grinding it to a fine powder.
- In the process of cutting unprotected diamonds may crack or break (it will happen faster than the harder and denser the material being cut).
- This erases the material to be cut metal mesh, thereby achieving the radial release of new diamonds.
In the diamond sector, ideally suitable material being cut, the balance between work and diamond frictional resistance is optimal; diamond is held in place as long as it is not completely destroyed and replaced by the new crystal does not appear. The quality of the diamond segment remains unchanged.
In the segments, designed to work with a hard dense (less abrasive) material, metal grille should be softer. It will iznashevatsya faster thereby be produced relatively rapid replacement of the diamond and the segment will continue to function.
The segments are designed to work with soft abrasive materials, have to be more rigid and resistant to abrasion, resulting in a diamond last longer.
The price of the diamond blade
Decide what is more important to you: the purchase price of the instrument or the value of a unit of production. To perform the less important tasks or irregular operation may come cheaper tools. For more important tasks, or for routine work is preferable to choose a more expensive instrument with low unit costs (per square meter), since it has the best characteristics and achieves better results.
being cut diamond blade material.
When you select the tool most important factor is the correct identification of the material to be cutting. This material directly affects the cutting speed and the real life of the tool. Incorrectly assume that for softer materials such as brick, you can buy a cheap drive and for solid - more expensive. From price will mainly depend disk resource (with proper selection according to the material). First decide on the appointment, and then decide for yourself with the issue price.
It is rarely possible from the first time to choose the right disk is ideal, since very large diversity of materials. If many expected the same type of work, it is necessary to select the drive trial and approximation. And in the end choose the high-end disk, has a maximum resource, but ideally suited to the material being worked. In this case, you get the maximum economic benefit. If the work is varied and you have a little work on the different materials, you can buy a universal (to some extent) drive low to medium price range. Dear drive in this case is not appropriate.
Dry or wet cutting?
Her choice may depend on the preferences of the user or by certain limitations associated with the work. For saws designed for cutting materials of concrete, wet cutting is preferable, because it allows you to cut the material more deeply and extend the real the life of the segment. Cutting boards and stone tools will be equally good for dry and wet cutting. For general purpose tasks often use dry cutting tools. Wet cutting is used primarily to limit the amount of dust. When uneven during high-power hand tools cutting dry, try using wet cutting. The problem will be solved by cooling. Some diamond blades, must be used with water. Tools dry cutting can be used with water, or without, depending on the tool and the material being cut.
