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.

There is centering degree of tungsten carbide ladder-shaped-thread-taps, so the thread is large. Therefore, to use a feed device with high precision. Screw machine and other machine tools used in the feed screw, almost all tungsten carbide ladder-shaped-thread-taps.

There are 30 degree tungsten carbide ladder-shaped-thread and 29 degree tungsten carbide ladder-shaped-thread, can be processed into a predetermined angle turn. 30 degree of pitch with tungsten carbide ladder-shaped-thread-taps, said 29 degree tungsten carbide ladder-shaped-thread according to the number of teeth to represent 1in.

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.

Darts was caught up in the high-tech materials revolution, and nickel-tungsten darts soon became ubiquitous. Before the age of Internet shopping, hundreds, perhaps thousands, of darts shops opened worldwide to provide a growing range of darts supplies to darts enthusiasts.

Dozens of darts equipment manufacturers, both large and small, provided a vast array of merchandise to these new shops. In the early years of the 21st century, the industry consolidated, became much more competitive, and many of these pioneer darts companies went out of business.

Technology continues to influence innovation in darts, as seen in the recent trend towards highly milled textures and finishes on darts barrels. Many of these new designs would have previously been very difficult, and certainly very expensive, to create. Computer controlled machining centers have now become affordable for even small factories, and these machines can repeatedly duplicate incredibly precise machining projects.

It seems likely that darts designs will continue to evolve along with the materials and technology used to make them.
