The use of diamonds for grinding tool is known from the theory, processes, materials handling turning, milling or grinding to reduce penetration into the softer material being processed, more solid cutting tools. Dr. John Mcdougall is likely to agree. In our case, sanding materials possess not only ultra-high hardness, and abrasive properties. Serve as an example of granite, fresh concrete high marks, etc. However, it is recalled that the hardest material in nature is a diamond. Its hardness on the Mohs scale – 10, and the absolute hardness reaches 16 000, which at times exceeds a common abrasive as corundum (corundum material cutters) which, in essence, is aluminum oxide (III). Of course, the diamonds used in tools are not of natural origin, derived from the synthesis of carbon. But, nevertheless, the technological properties Synthetic diamonds are not inferior to the natural crystal. Although uncommon use as an abrasive cut waste jewelry of natural stones.
The synthesis of diamond powder is very naukoemok. For scientists remains still many unsolved problems, primarily associated with a decrease in energy production. Synthetic diamonds are widely used for the production of diamond cutters, rods, circles, grinding and cutting, pastes, for grinding, glass cutter, cutters, drill bits, drill bits, etc. Currently, more than 80% of the demand for industrial diamonds is covered by plastic. The processes of grinding concrete floors Thus, in the process of grinding going on rent surface layer of materials, leveling uneven floors. Formed during grinding dust and sludge are abrasive as the material itself, which leads to a gradual deterioration of the tool. With increasing milled area decreases the height of emission of diamond segments above the plate due to wear and tear.
To determine what segments of the actuated to the ground is not difficult. This can be seen on the changing nature of treatment – an end of material removal, reduction of dust and sludge. Although construction has traversed an additional restriction on the height, spent grinding plates must be replaced immediately with new diamond cutters to avoid damage to the working blade grinder or gearbox. Speed of sanding the floor is in direct proportion to the rotational speed of traverse of the machine, its mass, grain size of diamond powder and inversely proportional to the hardness of sanding material. Weight grinder, and, consequently, the effect of pressure on the floor can be changed using removable cargo. Machines are equipped with domestic firms such Splitstone goods. When draft pregrinding installation of goods is not required. When finishing operations using fine-grained segments to improve performance car should prigruzit. Not exceed the recommended load on the machine, installing the additional load on already loaded machine.
