Two Important Roles of Cooling Liquid During Cutting
In addition to choose right cutting machine and install saw blade on saw machines rightly, you should have to pay attention on other factors if you want to use it for cutting rightly, for example, the choice of cooling liquid and the saw blade linear velocity.
As is known to all, when using cooling liquid, you want to get two purposes. Firstly, the role of cooling, during the cutting and sawing process, there would be strong friction between circular saw blade and cutting materials such as stone, because of such strong impact, there must be a plenty of quantity of heat, at the same time, stones materials always have poor performance of heat dissipation, as a result, lots of quantity of heat would be absorbed by the saw blade, especially the diamond tool bit, which would be damaged seriously. If such terrible condition lasts for a long time, diamond would be graphitized, as for the tool bit, it is easy to be burn and dropped. As for the matrix steel, it is easy to be out of shape because of high temperature and then crack from its root. Under such circumstance, lots of cooling liquid should be sprayed equably and persistently from the head saw blade to back saw blade, from left side to right side, saw blade would become cool and it is protected by cooling liquid.
The second purpose of using cooling liquid is to wash out the cutting crumbs. As you know, when cooling liquid rush into the cutting kerf, there would be a certain amount of pressure, which as usual should be greater than 0.1Mpa, with such great pressure, a large amount of small cutting kerf would be taken away, which is useful to reduced the abrasion on diamond tool bit and even its matrix, otherwise they are likely to be damaged by a mass of cutting crumbs accumulated at here because cutting quantity of heat can not be released.
In addition, if you used the cooling liquid which contains a certain amount of emulsified liquid, because of the feature of dissolving in both water and oil, there would be a thin layer of lubricative oil film on both the surface of saw blade and cutting stone, as a result, during cutting and sawing, friction coefficient would be reduced and cutting resistance, along with vibration, would be also reduced.
How to make cooling liquid? In fact, it is so simple, you can add a moderate amount of antirust agent and emulsified liquid into cooling water.
