Vitrified Diamond Grinding Wheel for Cutting & Grinding Natural Diamond

Diamonds are made of the hardest material in the world, only a diamond can be used to mechanically cut another diamond. Lasers are another alternative but their uses are largely limited to the cleaving and bruting purposes. Usually, the tools used in the workshop consist of diamond-bladed edges or cooper discs that are lined in diamond dust for cutting, while for the Grinding, Vitrified Bond Diamond Grinding Wheels could be used.

    Diamond cutting is the process that takes a rough diamond and changes it into a shaped and beautiful gem. The process must be undertaken by a professional with expert knowledge, equipment and tools for the job since every single decision made will affect the outcome of profitability.

This process will be involved into five steps: planning, cleaving, bruting, polishing and inspecting. Planning to cut a rough stone can actually be a time consuming process because this is the step that determines the final value of the finished products.


In the planning stages, the cutter will figure out the best possible shapes of the diamond in order to minimize waste and maximize the yield of the rough stone. Typically, the rough stone is mapped with a Sarin machine to generate accurate measurements. With this data, computer soft-wares are then used to form 3D models that will show the cutter the best way to optimize the rough.

  The cleaving process is the part that involves splitting the rough into separate pieces. This will then allow the cutter to work on the pieces separately and also to utilize the rough fully. Mechanical sawing can also be undertaken at this stage. In the case of oddly shaped roughs, the sawing process can also be undertaken with contactless cutting tools like lasers.

   After the diamond is split, bruting is then performed to make the separated rough stones round. This is process is also known as grinding. What happens here is that two diamonds are placed on a spinning axle across each other. They will then turn in opposite directions and grind against each other to create a rough girdle finish.
Faceting Process of Rough diamonds
A Diamond Polishing Wheel often was Vitrified Diamond Wheel with the rounded shape. The next stage is to create and form the facets of the diamond. The cutter places the rough on a rotating arm and uses a spinning wheel to polish the rough. This creates the smooth and reflective facets on the diamond.

The last stage is the inspection process. This is where the diamond is checked to make sure it meets the specifications set out by the manufacturer. If need be, the stone would be sent back to the polishers for some touching up if it didn’t meet the quality control standards.
