Asphalt cutter disc: mistakes not to make
The diamond blade for asphalt cutting is the most used product by professional companies. Fiber optic installation, system regeneration or simply road maintenance work require this essential tool. In this short article we highlight the problems and errors that can be avoided when using the blade to cut asphalt.
Asphalt cutting disc: different types
One of the first important factors for the use of the diamond blade is the asphalt cutting machine that is used. The market offers numerous variables based on the frequency of use and the depth of cut. For this reason it is essential to know the power of the machine's engine and consequently its peripheral speed.
It is no coincidence that a diamond blade for asphalt can have different cutting performances if mounted on a more or less powerful asphalt cutting machine.
Asphalt cutting: laying of optical fiber
If you are looking for an adequate solution for cutting asphalt in nano or micro trenches, know that even in this case there are numerous opportunities. The use of multi-discs that can be mounted on powerful machines is a new technology that offers excellent cutting performance with moderate speeds.
Today, in addition to diamond discs for single cut with multiple tools, Nord Srl also offers a specific product: a beating wheel for asphalt. This product is able to cut the road surface in one pass with customizable cutting thicknesses: 8/10/12/15/20 mm
Abrasion: The Worst Enemy of the Asphalt Cutter Disc
There are many legends about cutting asphalt told by many salesmen. However, the worst enemy of diamond blades is the abrasion of the materials. While hardness is easily workable, abrasion is the biggest challenge. Cutting asphalt in fact causes the metal alloy to wear out more quickly than the diamond. In this way, diamond products last less than expected if they do not have a very hard binder.
This explains why cheap products with soft binders cut asphalt without problems but with insufficient yields (about 50/80 ml).
Nord Srl has developed ad hoc formulas that have cutting yields from 400 to 1200 ml with excellent speeds.
Undercutting: How to Avoid It While the Disc Cuts the Asphalt
Another problem related to asphalt cutting abrasion is undercutting. This phenomenon occurs when the abrasive material remains in prolonged contact with the steel core. In this case the steel wears out and becomes thinner, causing the segment to detach.
To avoid this problem you can safely take two precautions. The first is to use the right amount of water avoiding excessive effort on the tool. The second is to buy diamond tools that have segments with the right labrating.
For over 60 years we have been producing diamond blades for asphalt cutters with diamond segments with thicknesses sufficient to avoid this problem. The difference in thickness between the diamond segment and the steel core allows a considerable distance between the cut material and the core itself. In this way, undercutting is easily avoidable.
Asphalt cutter for excavators
In collaboration with ECHIDNA and PR equipment we are developing an optimal solution for cutting asphalt for excavators. This hydraulic technology allows the user to cut asphalt with his excavator without the need for special adjustments. Unlike pick machines, it guarantees a clean, fast cut and small thicknesses.
