Shop of Artificial (Synthetic) Diamonds and Diamond Pastes
Terekalmaz Company has been manufacturing synthetic polycrystalline tungsten diamonds АPC-3, АPC-4 since 1977. Microgrits АPC-4 with the diamond cut from 2000/1600 up to 500/400 micron and synthetic tungsten diamond blanks of any geometrical form with the linear sizes of 4*4 mm (cylinder, cube, truncated cone, shank and so on) are produced now.
The good physical-mechanical properties and sufficiently high thermal stability allow applying the diamonds to manufacture various tools on metal bonds for working in especially heavy-load conditions, such as natural stone, concrete and building material cutting and processing, grinding wheel dressing, medium hard rock drilling including petroleum and gas drilling.
Since 1988 the factory has been producing monocrystal diamond microgrits of the AC type of different marks in accordance with All-Union State Standard 9206-80 (GOST 9206-80) [AC is the Russian abbreviation for Synthetic Diamond (SD)]. For example, АС4 – АС6 microgrits for manufacturing tools on organic, ceramic and metal bonds. These tools are used for processing hard alloys, glass, porcelain, ceramics and for honing hardened steels and cast irons.
АС15 – АС32 microgrits are used for grinding, cutting, drilling natural stones, reinforced concretes, refractory products, glass, leucosapphires, rubies and other hard materials.
АС50 – АС80 are diamonds for tools working with higher specific loads. They are used for processing, cutting and drilling quartz glass, corundum, natural stones of hyperhardness, and also for straightening.
On the basis of the produced microgrits and micropowders both synthetic, and natural, the diamond paste is produced for finishing, lapping and polishing surfaces of various products made of metals, alloys and nonmetallic materials (semiconductors, semiprecious stones and precious jewels, etc.).
Diamond pastes are complex multicomponent systems being composed of a paste body and some diamond powder. According to the materials used for the paste body (surface-active substances, amendments, lubricating substances, additives and others), they are subdivided into washable away by water (W), washable away by organic solvents (О), washable away by water and organic solvents (WO). The pastes can be of unctuous or solid consistency.
Terekalmaz Company produces diamond pastes of unctuous consistency washable off by organic solvents (О) and water (W) made of natural and synthetic diamonds, with normal (N), increased (I) and high (H) concentration of diamonds.
Drills for drilling holes in concrete, marble, granite, ceramics, other hard nonmetallic materials are made of high-strength polycrystalline diamonds. The drills of 6 and 8 mm diameters are manufactured.
