DIAMOND

It is one of the organic origins of carbon minerals. Tough: 10 Oz. A.3.51, Shape: Cubic, Modulus of rupture: 2.5. Melting Point: 3845 C. It is colorless and transparent as well as yellow, red, blue and black. Although it is electric with rubbing, it does not transmit electricity and heat. It is pure carbon. At 770 C, it burns without ashes.

Diamonds used in the manufacture of diamond grinding wheels can be divided into two categories: natural diamonds and synthetic diamonds. Since 1957 when synthetic diamonds were introduced into the market, their use has increased steadily. Nowadays synthetic diamonds are accepted as the main material for diamond grinding discs in the industry.

TYPES OF DIAMOND

Natural Diamond: Used in electrolytic coating and thin-grinding.

Synthetic Diamond: It is used for all types of abrasive work in organic and mechanically connected discs. Surface coated types are available. Super grinding and polishing paste are made with synthetic diamond. Synthetic diamond types are titanium, nickel, copper, silver coated ones.

USAGE AREAS

CBN (CUBIC-BORON NITRIDE)

It is a kind of abrasive obtained from chemical processes of Boron and Nitrogen elements.

Its physical location, atomic structure and crystallization properties are very similar to diamonds.

It has very good results in abrasion of high-speed steel, tool steels, carbon steels and hard ferro-titanium alloys. It is harder than Silicium Carbide and Curedondan. In the aerobic environment, CBN is resistant up to 1400 C.

CBN TYPES

It has different acoustic elastic types compared to synthetic diamonds.

There are varieties covered on the surface. These CBN types are those coated with titanium, nickel, copper and silver.

USAGE AREAS

• High Speed Tool Steels
• High Alloy Tool Steels
• Chromium steels (25% Cr)
• Heat treated steels
• Special alloys
• Stellit
• Steel alloys (HRc3 58)
