If you are a gold dealer and attend some trade fair or put your gold products in the showcase, what you want least is your gold products are stolen.

However, your shining gold products are always very attractive to the thieves. In order to reduce any possible great loss, you'd better to put a fake, but a very similar substitute for gold products.

Tungsten alloy golden rod or gold-plated tungsten rod are the best choice.

Tungsten carbide planer for planing, with a cutting tool parts. Tungsten carbide planer can be divided according to use longitudinal, transverse, grooving, cutting and shaping planer and so on. For planing, the tool having a cutting portion.

Tungsten carbide planer’s structure substantially is similar to turning, but the work was interrupted cutting planer, by the impact load. Therefore, in the same cutting section shank tools sectional size large than 1.25 to 1.5 times, and using large negative blade angle (-10 ° ~ -20 °), the cutting edges to improve the performance impact loads.

Tungsten carbide thin-shank-machine-tap is used for fine machining deep hole common thread (GB192 ~ 193, GB196 ~ 197) of the internal thread.

Tungsten carbide thin-shank-machine-tap’s features and precision: fine shank machine taps rotate clockwise direction, the precision is divided into three tolerance levels. That is: H1, H2, H3.

H1 level: suitable for processing thread 4H, 5H's;

H2 grade: suitable for processing 5G, the internal thread 6H;

H3 level: suitable for processing 6G, internal thread 7H, 7G's.

Tungsten carbide 60-cylindrical-pipe-thread relies entirely on their own to form a seal between the threads without any sealing medium. Dry seal pipe thread stipulates a more stringent tolerances, precision metal thread , only on special occasions.

Tungsten carbide 60-cylindrical-pipe-thread has high strength and good sealing, the use of threads on the brittle material having a thin cross-section can reduce breakage. Tungsten carbide 60-cylindrical-pipe-thread between internal and external thread with no gaps, isan interference fit. There is transition cooperation with Tungsten carbide 60-cylindrical-pipe-thread. It is mainly used for high temperature and pressure on the sealing demanding places.

Tungsten carbide 60-cylindrical-pipe-thread, is also known as NPTF. US-made dry seal tapered pipe thread, National (American) Pipe Thread abbreviation belonging to the American standard 60-degree taper pipe thread for the North American region. Its tooth type angle of 60 degrees, cone degrees 1:16 taper limit deviation of -0.005 ~ +0.005 mm / mm NPTF thread of one and two two levels.

For the level, to test the height level of the thread. When a standard test can be omitted NPTF male thread, to ring simultaneously with the L1 and L2 ring; within the detection tungsten carbide 60-cylindrical-pipe-thread, we should use with the L1 plug and L3 plug at the same time.

In the sealing mechanism, tungsten carbide 55-tapered-pipe-thread-tap, with its unique sealing effect, are widely used. But in machining, the parameters listed in the various manuals, without exception, to the base surface is given in a standard size.

This abstract dimension, both in the actual processing is difficult to measure and difficult to control, resulting in the processing of the thread will vary and reduces interchangeability. Tungsten carbide 55-tapered-pipe-thread-tap are in the assembly, not the song is tight, not difficult to install, but also seriously affect the sealing performance. By now translated, with precise, habitual use of lip dimension to replace the complex base size, not only more convenient processing, and significant progress in tungsten carbide 55-tapered-pipe-thread.

Tungsten carbide ladder-shaped-thread to be processed, to start with, the processing time of the rectangle, just to try to make the size of the processing to eight points. A thread of a rectangular feed only about 0.05 ~ 0.1mm. But deep trench, it will take a lot of time. While machining the teeth side of the feed 0.05mm, there will be an angle of 30 degrees.

Scale readout = 0.05mm * cot15 degree
= 3,732 ≈ 0.2mm * 0.05mm

It will produce four times the original amount of chips. In other words, the same chip, because the thread lead angle, the movement of the cutting edge length becomes longer, the chip will be thin.

Tungsten carbide ladder-shaped-thread is mainly used for feeding device, the thread is basically for a softer non-ferrous metals. Especially brass, bronze, chips can be well drained from the outset with the form tool linear feed can be.

Generally, the tungsten carbide ladder-shaped-thread is bigger than the triangle’s, so cutting capacity is much, and the feed screw triangle method is different. According to the basic tooth type tungsten carbide ladder-shaped-thread-taps, with a bottom width of the rectangular teeth begin processing thread turning moment tooth width table thread.

Compared to the width of the teeth at the end of the larger rectangle with the general thread, so people need to take a good angle.

Secondly, with the basic tooth type matches the turning tungsten carbide ladder-shaped-thread-taps flank both sides of finishing. Order processing flank, tungsten carbide ladder-shaped-thread-taps’ teeth will increase, a force when turning machining on both sides too, so side to side processing.
