Circular blades
Different materials represent different challenges and our vast range of specified bonds along with a choice of standard noise reduced steel centers provide perfect solutions. We particularly recommend that the blade to be used should suit the material to be cut.
Each material or group of material has its own particular hardness and abrasive properties. The type of blade is determined by these two factors. Therefore it is easy to foresee that a change of material can be fatal to the tool life.
A blade intended to cut marble, for example, will be completely worn after sawing a few square meters of soft sandstone, which is softer but more abrasive than marble. Especially developed to cut all kind of granite, marble and other stones our blades will respond to all and even more than you demand. The correct identification of the material to cut is the most important factors for choosing a tool.
Type of rim
A) The blade with continuous rim guarantees a clean cut.
B) The blade with grooved super-joined segments has a longer practical life and offers a much lower cost per cut than the continuous rim blade.
C) Segmented dry blade with narrow slots and key hole.
D) Segmented wet blade with narrow slots.
E) Segmented blade with wide slots.
Attaching diamond segments to the steel core
The diamond segment can be attached to the steel center using two basic methods:
Brazing
The segments are attached to the core by brazing with silver solder.
- Used on standard blades for wet cutting
- Do not use for blades for dry cutting!
Laser welding
Segments are welded to the center using a laser beam.
Strongest bond possible between steel center and segment. Suitable for wet and dry cutting applications. The laser-welding process is the latest state of the art method to attach diamond segments to the blade center. This process assures a maximum degree of safety.
finishing operations
After the assembling process, each individual segment undergoes double-sided cross-bend tests to ensure that they are solidly fused to the center. Tension must be put on each blade to assure that it runs straight and true even under tough cutting conditions.
Each blade is tensioned by hand; a process performed by specialists who are skillfull experts in their craft. Each blade is sharpened, at the factory to make sure that the blade will cut freely, the very first time your customer will put it to use.
The last steps – finishing, painting, printing and packing – are performed with the same amount of care and concerned for quality as you already have seen in the manufacturing process.
