SIMA has a longstanding experience in diamond blades, both as a natural complement to our machines and as a product traded under SIMA brand.
For more than 20 years we have evolved to the market requirements, and currently offer two quality levels according to each customer needs. A diamond blade is made of a body or core of high precission steel to which cutting segments are added. These segment are made of a mix of metal powder (a combination of different elements, such as cobalt, tungsten, zinc, iron, etc.) and a resin to make the bond.
This mixture is also combined with diamonds of different size and hardness, and in a certain concentration. Finally, it is shaped as a blade segment in which the composition of the metal powder and the size and concentration of diamonds has been choosen accordingly with the kind of material that it will be cut.
The result is later put through a thermic process to transform it into a metalic segment, hard, and very resistant.
SIMA technicians consider all the needful variables when recommending the blade that best adapts to every specific cut.
Choosing a Diamond blade
As a general rule, it can be said that cutting soft or very abrasive materials is a job for a hard metal and a lower diamonds concentration segment.
For a hard material, the segment needs to be made of a softer metal bond and bigger sized diamants. But each case must be carefully analyzed to achieve the right balance for the best possible cut.
The same material may have a slightly different composition. For instance, marble, according to its origin (Carrara, Sweedish, Vermont, etc.); or the granite (Alkai, Tonalite, Binary, Riolite, etc.); even concrete, depending on the aggregates used in its composition (sand, gravel, stone, recycled concrete, etc.)
As a result, even on namely the same material, the blade performance can be different depending on the its specific composition and the abrasiveness linked to it.
For our customer, the decission is not as hard as it seems: he just need to tell us what material he needs cutting, what machines he will be using to cut and the blade diameter.
SIMA DIAMANT offers two blade ranges: PLUS series and PREMIUM series. The choice will depend on the required performance: the PREMIUM blades feature a higher segment.
A segmented disc is mostly recommended to cut hard materials, such as stone, granite, bricks, etc.) when a very high cutting precision is not essencial and speed is.
A turbo disc improves the cutting precision in those materials that are subject to be chipped, providing a neater cut at a reasonable speed. A continuous rim blade is perfect for ceramic materials requiring cutting accuracy and a very clean cut.
Sima Diamant has the widest range of machinery for the manufacturing of diamond blades & core bits, such as metals casting, sintering, vacuum & galvanic casting. The assembly processes are automatic & robotized to include laser welding, the high-frequency welding and gas welding.This process makes our saw blades unique.
Our R+D+i department is geared to provide solutions on the design of new products. It is equipped with a metrology laboratory featuring state-of-the-art scientific instruments for analyzing, measuring & assessing the materials, compositions, hardness, density, quantity and type of diamonds of each segment. As a result, SIMA provide the finest diamond blades and saw blades a company can possibly create.
