Brazed tungsten carbide turning tool is a type of commonly used brazed turning tool with high hardness and thus can meet the needs of most of machining materials. Brazed turning tool, as its name implies, is a type of tool in which the blade and the shank are tied by welding.
Brazed tungsten carbide turning tool is simple in structure, easy for manufacture and flexible in use and can be sharpened according to different requirements. It has high stiffness due to its material characteristics. However, it also has its disadvantages, which lie in its relying the cutting properties on the sharpening technology by manpower. In addition to that, its shank cannot be used repeatedly. If the blade is worn or broken, then the shank will also be out of use.
Brazed tungsten carbide turning tool, according to its properties and objects, can be divided into three types: the red shank type, the yellow shank type and the blue shank type.
The red shank type is made of YG tungsten carbide, which is represented by YG6 and YG8. It is mainly used in the rough machining of cast iron, non-ferrous metal and non-metallic material. This type of carbide is of high bending resistance but poor abrasion resistance, thus is only suitable for low-speed processing.
The yellow shank type is made of YW tungsten carbide, which is represented by YW1 and YW2 and is mainly used in the semi-finish and finish processing of high-viscosity material like stainless steel. This type of carbide is of high hardness, good abrasion resistance and universality but low bending resistance, thus is only suitable for high-speed feed processing.
The blue shank type is made of YT tungsten carbide, which is represented by YT15 and YT5, and is mainly used in the machining of 45# steel and ordinary steel. This type of tungsten carbide is of high hardness, good abrasion resistance but low bending resistance, thus is suitable for rough processing and semi-finish processing.

Tungsten carbide threading turning tool is used in thread machining. Currently, due to the characteristics of numerical control machining, the traditional high speed steel turning tool can no longer meet its needs. Nowadays, the threading machining in cast iron material often uses YG tungsten carbide, while that in steel material often uses YT tungsten carbide, such as YT15. This type of cutting tool is of wide universality, not only suitable for rough machining but also finish machining.
Tungsten carbide threading turning tool can be divided into two types, which are internal turning tool and external turning tool, among which, it can again be subdivided into the solid type and the clip type. The clip type threading turning tool is increasingly common in use. The structure of clip type threading turning tool has two main parts, which are the shank and the blade. There is a shim on the shank, which is fastened by a bolt and the blade is installed in the shim. There are two types of blades in the clip type turning tool, that is uncoated tungsten carbide blade and coated tungsten carbide blade. The former one is generally used in non-ferrous metal machining, which include aluminium, alloy, copper, copper alloy etc., while the latter generally in rolled steel, cast iron, stainless steel, alloy, and so on. Coasting can greatly extend the blade’s service life.

Tungsten carbide nozzle, with high hardness and high abrasion and corrosion resistance, is a kind of tungsten carbide product used in surface treatment, sand blasting, paint spraying, electronics and other industries.
Tungsten carbide nozzle requires a certain roughness in its surface, therefore, it is necessary to conduct grinding finishing towards its surface to achieve the roughness required. Centerless grinding is often adopted in this process. Centerless grinding consists of grinding wheel, adjusting wheel and work supporting device. Tungsten carbide nozzle centerless grinding can help it gain roughness required in installation.
Tungsten carbide nozzle centerless grinding can contribute to producing tungsten carbide nozzles of high size precision and smooth surface with the help of universal grinder grinding towards the inner surface.

Tungsten carbide nozzle can be classified as several types like fan-type nozzle, cone nozzle, solid stream nozzle, and so on, among which, cone nozzle can be again subdivided into solid cone nozzle and hollow cone nozzle.
Tungsten carbide solid cone nozzle has compact structure, good atomization effect and excellent technical performance, and can produce solid cone spray shape with angles of 30~120°. It can produce uniform distribution of spray with medium to large size spray drops, which owes to the unique blade design. The large unobstructed flow channel and advanced jet control character contribute to achieving amazing effect in the jet application field requiring coverage of a whole area.
Tungsten carbide hollow cone nozzle can produce hollow cone spray shape with angles of 51~114°. It can produce uniform distribution of spray with small to medium size spray drops under a wide range of flow rate and pressure.
In addition to regular tungsten carbide cone nozzle, there are also square standard angle nozzle,straight line hollow cone nozzle and other types of nozzles, and they can even subdivided into standard angle and wide angle. Choices of nozzles should be based on different applications.

Golden tungsten bar is manufactured in the form of bar, which is rectangle. Tungsten alloy is first made before plating gold on it. The tungsten alloy bar also has the properties of tungsten-high density and corrosion resistance. Therefore, the value would be remained as gold for the increasing value of tungsten and gold in August, 2011.
After the manufacturing of tungsten alloy bar, engraving should go next. After the choosing of letters, our technician would think of the difficulties of engraving, and work out methods of appropriate proportion to engrave. We always engrave words as customer' s drawings.
When engraved, the tungsten bar can be chamberred, for that people are not to get hurt form the sharpe edges. However, the unchambered tungsten golden bar also has the pleasant suface.The last procedure of manufacturing tungsten golden bar is to plate gold of 18K or 24K on it. This is also a choice made by customers.

Tungsten Carbide Self-excited Pulsed Nozzle Introduction
- Category: Tungsten Information
- Published on 17 October 2014
- Hits: 570
Tungsten carbide self-excited pulsed nozzle is developed and manufactured according to the principle of self-excited oscillation and can be used as the nozzle of roller bit. It addition to possessing the excellent properties of common tungsten carbide nozzles, it also has its unique property of intermittent jet, which improves operation efficiency.
The principle of tungsten carbide self-excited pulsed nozzle is as follows: The water jet flow coming out from the upper part of the nozzle is reflected by the upper and lower surfaces. The reflection pressure wave in the upper surface equals to the initial phase of water pressure wave moving downwards and thus forming wave superposition, which hit the jet flow reflected by the lower surface, resulting in strong circular shear stress, which makes high shear jet stream into instantaneous vacuum form alternating water bomb. High pressure generated in the vacuum projects the water bomb at a high speed, forming discontinuous water bomb jet flow, and thus overcoming the disadvantages of low energies of continuous jet nozzles and improve the instantaneous impact force of the jet effective spray distance and the hydraulic energy when the jet flow arrives at the cleaning area.
