Tungsten Carbide Die Milling Cutter Introduction

Details: Category: Tungsten Information; Published on Monday, 03 November 2014 18:19; Written by xjq; Hits: 572

Tungsten carbide die milling cutter, also called tungsten carbide high-speed mixed milling cutter or tungsten carbide rotary file, can be compatible with high-speed electrical machines or air tools. It can be used in the finish machining of various kinds of metal die cavities and inner bore surface of machine parts; cleaning the trimming, burr, welding line of castings, forgings and welding; chamfering, rounding, groove and keyway machining of different types of machine parts; sleeking of impeller passages; and cleaning of pipeline.

Tungsten carbide die milling cutters gain wide applications in mechanical, automobile, shipping, chemical, carving and other industrial sectors, and achieve good effects. Its main applications include:

I. Finish machining of various kinds of metal mould cavities, like shoe mold.

II. Handicraft carving of various kinds of metal and nonmetal.

III. Cleaning the trimming, burr, welding line of castings, forgings and welding, such as in casting machining factories, shipyards, automobile factories, etc.

IV. Chamfering, rounding, groove and keyway machining of different types of machine parts, such as in machinery factories, repair factories, etc.

V. Sleeking of impeller passages, such as in automobile engine factories.

Tungsten Carbide Cutting Tool CVD Coating Technology Development

Details: Category: Tungsten Information; Published on Monday, 03 November 2014 18:17; Written by xjq; Hits: 583

Tungsten carbide cutting tool coating previously usually adopted high-temperature chemical vapor deposition (GTCVD) technology. According to the constituents of the sediment, clean gases like H2、CH4、N2、TiCl4、AlCl3、CO2, after mixed in a certain proportion, are applied on the blade surface of tungsten carbide cutting tool with certain temperatures (generally 1000~1050℃) in the deposition system under ordinary or negative pressure. Up to now, HTCVD is still the most popular technology in this area. In addition, there is also anther technology called plasma chemical vapor deposition (PCVD) applied in tungsten carbide cutting tool coating. Due to its relatively low technological temperature (700~800℃), it reduces the bend resistance of the blade.

Later on, multilayer coating with different combinations have been developed, such as TiCN/Al2O3、TiCN/TiC/TiN、TiCN/TiC/Al2O3、TiCN/Al2O3/TiN、TiCN/TiC/Al2O3/TiN、TiCN/Al2O3/TiCN、TiN,TiC/TiCN/TiN、TiN/TiCN/TiN and so on.

We can clearly see that in recent years, TiCN or TiN are often used as the bottom layers due to the improvement of tungsten carbide substrate. For example, gradient structure is taken, so that it is possible to take TiCN or TiN as the bottom layers. Besides, TiN is not suitable to be applied alone, because TiN has less improvement in its hardness compared with tungsten carbide. That is why TiN has to be used in combination with TiC, TiCN and Al2O3.

Tungsten Alloy for Efficient Radiation Protection

Details: Category: Tungsten Information; Published on Monday, 03 November 2014 13:59; Written by Cher; Hits: 543

The tungsten alloy reliably shields against X-rays and gamma radiation. With its new production process and great expertise in the materials field, PLANSEE has made the manufacture of shielding components particularly cost-effective.

Whether in the world of medical or industrial X-ray technology, radiotherapy or nuclear power stations: Wherever high-energy radiation is used, it is vital to protect people against it.

The denser the material, the better able it is to protect from radiation. That is why heavy elements absorb X-rays and gamma radiation particularly well. Lead is still the most frequently used shielding material. Because it is a very soft material, it is mostly used only in combination with support structures made of steel.

Lead is a toxic material that is harmful to the environment and humans. The onerous recycling process makes lead expensive despite the low initial procurement costs. Many enterprises are therefore looking for a suitable alternative for providing reliable radiation protection.

High-Density Heavy Metals for Radiation Shield

Details: Category: Tungsten Information; Published on Monday, 03 November 2014 14:02; Written by Cher; Hits: 558

Heavy metal alloy composed primarily of tungsten. Heavy metals manufactured by our advanced powder metallurgy feature very high density and excellent radiation shielding as well as mechanical strength and machining/processing characteristics. These metals have been well accepted as alternative materials of lead that has adverse impact on environment. They are also used for various weights and rotors and for their excellent shielding performance, in a variety of fields including medical equipment and nuclear power plants.

Compared with other metals, our heavy metals are far superior in terms of absorption of high-energy beams and radiation. They have extremely low gas emissions in high vacuum and are superior in mechanical strength and processing workability. They are ideal materials for such applications as medical equipment, nuclear power plants and other radiation shielding applications.

Tungsten Nail Sinkers

Details: Category: Tungsten Information; Published on Monday, 03 November 2014 13:41; Written by Sherry; Hits: 606

Nowadays, a popular approach to weighting down soft plastics is the advent of small tungsten nail sinkers to add small amounts of weight internally to soft plastic lures.

Tungsten nail sinkers are thin and nail-like weights insert into soft-plastic baits, like jerk baits, sticks or finesse worms. Tungsten nail sinkers can be used to balance rigged jerk bait for a natural-looking fall. Another option is tail-weighting finesse worms for a tail-first, fall that can trigger hits from shy, following fish.

Tungsten nail sinkers are perfect for adding a small amount of weight to your soft plastic lures. An adjustment in weight can make the difference when conditions on the water change or you want to modify your bait's action. Easily clipped down with standard line clippers, tungsten nail sinkers are an ace-up-your-sleeve. The ability to make quick changes helps you stay one step ahead.

Each active tungsten nail sinker comes with three factors: a sharp tip to penetrate any section of the soft plastic lure, a narrow shank profile to minimize damage to the soft plastic lure and a set of conical barbs along the length of the shank to securely fasten the tungsten nail sinkers into the body of your soft plastic lure.
