In the mid-to-late 1980s of the 20th century, most of the rotary file coarse tooth F is still relying on hand-made to carry out manufacturing and manufacturing, and then it will be accompanied by the continuous development of computer-controlled machining technology. Automation Technical equipment has been gradually popularized, so with the help of them, they can engrave the official seal and turn it out in all ways.

It can also be used according to the trimming of the tail to make it have the requirements for drilling coarse teeth H. The rotary file with the characteristic Z is produced by the CNC machine tool equipment on the computer. The main use of cemented carbide tool rotary files is very common. It is widely used in machinery, equipment, vehicles, and chemical process manual engraving. The actual effect is very obvious. The key main use is

1. Deep processing of various metal material molds and concave molds like shoe molds

2. The processing technology of various metal materials and non-metal materials, the manual engraving removal of carved parts and craft products

3. To block the burrs, burrs, and welding of welded parts, such as tin foundries, shipyards, automobile manufacturers, etc.

4. Used in processing plants of various mold parts to professional choreographers, production and processing of cleaning pipelines, production and processing of the inner thread surface of mold parts, to foundry auto repair shops, etc.

5. Repair the light-like vehicle engine factory at the impeller landing position

The key features of carbide tool rotary files are as follows:

1. Ability to drill, produce and process various metal materials and non-metal materials below HRC70 at will

2. For a large part of the work, the brochure can also replace the small sand wheel, and it can produce dust and zero pollution.

3. The high efficiency of production is very high, which is 10 times higher than that of manual production and processing, and the production and processing efficiency of coarse tooth L is nearly 10 times higher.

4. The quality of the production and processing is very good, the smoothness is extremely high, and it can produce high-precision molds and cavities of various shapes.

5. The application has a long service life, 10 times higher than the wear resistance of the spring steel CNC blade, and 300 times higher than the wear resistance of the aluminum oxide sand wheel.

6. The operation method is very simple, convenient and reliable, which can alleviate the compressive strength of employees and improve the natural environment at work

7. It can greatly increase the economic benefits, and the comprehensive production cost can be reduced by several times.

In real life, there are still some manufacturers who make rotary files by hand. In fact, the products they produce are very untidy. In the case of application, it is very easy to produce vibration, cracking of the cutting edge, and damage. Situation, so the actual operation will cause many inconvenient areas.

However, after the rotation produced by the CNC machine tool equipment, the groove width is very neutral and the key parameters of the equiangular rotation angle of the steel are also very high reliability. As a result, it is naturally produced with equipment. The actual operation of manufacturing is more convenient, the operation is more stable, and the actual effect of production and processing is better. The overall view is Z effective.
