There are various procedures involved in diamond processing. Among them, the method for separating diamonds can be categorised in three types. They are separated by sawing, cleaving, and laser beam. The principal methodology is sawing, and it is also the most effective methods. Special saw machines are used for the operation. The diamond sawing machines come with blades bearing diameters and thicknesses ranging from 76mm and 0.04-0.14 mm respectively. There is a specific rotational velocity as well ranging between 6000 and 12 000 r.p.m. The periphery of the disc is embedded within the diamond powder. As the sawing operation takes place, the surface of the diamond tends to be smooth and flat. In case the perfect texture is obtained, the procedure tends to get more comfortable. The polishing time reduces, and there is less chance for the diamond to lose the real weight and the size.
The favourable cutting angle, the positioning of the diamond and the particles embedded in the disc must be discussed. Thus, the rake angle tends to get almost zero. There are also procedures to have control over the size of the grain of the diamond powder while conducting the cutting operations.
Sawing modes prevalent in the diamond industry
There are two main modes for diamond sawing prevailing in the industry. One of the methods employs a hole circular in diameter placed at the middle of the disc. Whereas, another way utilises disc periphery for operating the saw properly. The hole method is much useful as it opts for tensioning of the disc. Therefore, a better level of lateral stability during the sawing process can be achieved. Another approach involved in sawing is the calculation of the tangential and the radial stresses.
