Diamond tools – all about diamond laps

When a stone is cut, especially granite, the material requires special equipment in order to be cut properly. Such equipment should be durable, allowing to obtain the desired effect. Due to the fact that the stone is a very hard material with a compact structure, diamond tools have been created allowing precise and quick cutting, grinding, etc. In this article, we focus on describing the most popular tools of this kind, namely diamond laps. We have compiled all the important information relating to these products and created one small article. You fill find all the details below, enjoy reading!

Diamond Tools – important information about the laps

  1. Construction of the diamond laps

Diamond laps consist of two parts: the steel body and the rim on which the diamond grains are found. The rim may be fully covered with the grains, there can be diamond segments on the rim, as well as side blades. The body, on the other hand is made from high quality hardened steel and has on its surface water lines which cool the blade during its use, by making the water or air (depending on the machine) flow through the lines/cuts. In most cases, the above-mentioned diamond tool bodies are pre-tensioned so that they are sufficiently rigid and resistant to bending. However, during their production the diamond segments are made of diamond grains and metal powders, which are conjoined together using heat and pressure (a process also known as sintering). It should be noted that diamond grains are synthetic, have different quality, size and granulometry. Of course, they are always made a little larger than the body, so that after their imposition, the edge extends beyond the lap. As a result, during its use, the body is out of contact with the cut material. In terms of the connections of the body to the rim, it is carried out it using several methods. These include soldering using silver alloys, laser welding (in most cases this process produces diamond tools for dry) sintering of the body (ideal for manufacturing laps with a continuous rim) and the plating technique, which involves a deposition of diamond grains with metal.

  1. The way the diamond lap works

First of all it should be mentioned that the lap does not cut the material, but it rubs it instead. It must be very sharp, because only then it is possible to obtain a fairly smooth edges and precise cutting of all elements. The largest part of the process consist of diamond grains appearing on the front of the blade and side surfaces of the rim. It is them that rub the stone, while the comet, which is the grain on the back form an adhesive press thus increasing their clamping force in the binder. Of course, it needs to be considered that the frequent use of the diamond tools leads to their eventual loss, in fact to be precise, the outer layer of the lap is rubbed off. It should be added that the treatment may be accompanied by crushing of the stone and breaking off the diamond grains. We see this in particular during polishing or cutting of dense and hard stone. Unfortunately, this leads to a rapid wearing of the blade, therefore the laps must be very precisely selected in accordance to the type of the stone – paying close attention to the properties of the material. It is generally thought that the cutting of hard stones leads to the use of blades with a soft binder, and the cutting of soft stone is equal to the use of blades with a hard binder.

  1. What to keep in mind when choosing these products?

When choosing such products, bear in mind that the diamond tools serve longer if they are wet. However, in some cases, the process of wetting the blade is impossible. Then, of course, a dry lap should be used, making sure that a suitable amount of air is delivered during the work. Another issue is the type of edge. The best and most durable edges are diamond blades with continuous/segmented rim. They are the cheapest materials and wear the slowest, but most of all, they guarantee the highest quality of cut. It is worth noting that it is much better to avoid reaching for ‘universal’ products. They are usually very poor – so it is a much wiser choice to invest in several discs and adjust them to the type of the material, because then the effect will be the greatest. Naturally, in the course of making a choice you must also have in mind the technical parameters of the tool, which we will use in order to work with the material. The construction of the machine and its dimensions are also of considerable importance and determine the choice of a suitable grinding tool.
