Tungsten Nail Sinker Advantages

Category: Tungsten Information
Published on 06 November 2014

Made of tungsten, tungsten nail sinker is designed specifically for the professional soft plastic bait angler to give anglers the extra edge against the competition.

And depending on where the tungsten nail sinker is inserted into the body of the soft plastic lure, the tournament angler is able to effectively tune the rolling action, diving pitch and buoyancy of the soft bait plastic lure to mimic an injured bait fish.

Tungsten nail sinker has the added benefit of being smaller than lead, thus reducing impedance of hook set. Tungsten nail sinker features barbs to help keep the sinker in place and ridges to prevent them from slipping out of the plastic. They can be took up in your tackle box, if consider carrying a few of these weights on hand, just given the limited space.

Tungsten Carbide Multithread Hobbing Cutter Introduction

Category: Tungsten Information
Published on 05 November 2014
Tungsten carbide multithread hobbing cutter is a kind of cutting tool used in gear machining. The kind of hobbing cutter normally adopted is single-thread hobbing cutter with only one helix, while multithread hobbing cutter is of several helixes. Generally, when the number of thread in a hobbing cutter increases, its efficiency will also be higher, but the gear being processed will lower its quality. Other cutting parameters remaining the same, when the single-thread hobbing cutter makes one rotation, the gear processed will move one of its teeth, and when the multithread hobbing cutter makes one rotation, the gear processed will move several of its teeth. It seems that the efficiency of multithread hobbing cutters will be much higher than that of the single-thread ones, but actually it is just a theoretical assumption. The fact is the tungsten carbide hobbing cutter should change its corresponding parameters taking into consideration various kinds of parameters like the rigidity of machine tools, so its efficiency is actually lower than the theoretical one. In addition, its machining precision is lower than that of the single-thread hobbing cutter due to the influence of its indexing accuracy. To put it simply, multithread hobbing cutters have lower precision but higher efficiency than that of single-thread hobbing cutters.
 
However, due to the high processing efficiency, if the machining precision of the tungsten carbide multithread hobbing cutter can be improved, it will surely gain wider and wider applications in gear machining.

Tungsten Carbide Cutting Tool Machining Methods

Category: Tungsten Information
Published on 05 November 2014
Tungsten carbide cutting tool when used in machining has four main machining methods to achieve shape precision, which are movement track method, rapid prototyping, form copying method and generating method.
 
I. Movement track method
Also known as tool nose movement track method, it achieves shape precision through the movement track of tool nose. When the tungsten carbide cutting tool moves around the workpiece, the surface geometry required will be obtained according to the movement track of the tool nose. 
 
II. Rapid prototyping
It is a kind of machining method carried out by using formed tungsten carbide cutting tools. The cutting edge of formed cutting tools is the shape of workpieces. This method can simplified the machine tool and cutting movement and thus improve efficiency.
III. Form copying method
When form copying method is adopted, the cutting tool will conduct machining according to copying device. The shape precision achieved by adopting form copying method depends on the precision of the copying device and that of its forming movement.
 
IV. Generating method (generation method)
In this method, the workpiece and the tungsten carbide cutting tool do generating motion during machining. The surface gained by adopting generating method is enveloping surface formed by the generating motion done by the cutting edge and the workpiece. The cutting edge shape must be the conjugate curve of the surface being processed.

Tungsten Carbide Boring Cutter Types

Category: Tungsten Information
Published on 04 November 2014
Tungsten carbide boring cutter can be classified into single-blade boring cutter, double-blade boring cutter and multi-blade boring cutter according to its cutting blade number; into-hole boring cutter, blind hole boring cutter, ladder hole boring cutter and end face boring cutter according to its machining surface; into solid type, fabricated type and adjustable type according to its structure.
 
The two types of tungsten carbide boring cutters most commonly seen will be introduced in the following:
I. Single-blade boring cutter
The cutter bit structure of single-blade boring cutters is similar to that of turning tools. The cutter bit is installed in the cutter bar and is fixed by bolt according to the bore diameter of bores to be processed by hand. Single-blade boring cutters, with simple structure, have wide applications and can be used for rough, semi-finish and finish processing. However, the size of bore diameter being bored has to be ensured by adjusting the length of overhanging by hand. Therefore, it is to some extent troublesome. In addition, there is only one main cutting edge involved during boring, so it has relatively low efficiency, and is thus usually used in unit production.
II. Double-blade boring cutter
It has two symmetrical cutting edges and the radial force can cancel each other out during boring. The bore diameter size and precision of workpieces are ensured by the radial dimension of tungsten carbide boring cutters.

Tungsten Carbide Cutting Tool CVD Coating Technology Development

Category: Tungsten Information
Published on 03 November 2014
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.
