CNC milling is gradually active in the market and widely welcomed by people. This is an automatic processing equipment, which is developed on the basis of ordinary milling machine. CNC milling machine is controlled by computer digital signal, and their processing technology and structure are roughly the same. In this paper, we introduce the characteristics of CNC milling machine and the calculation method of surface velocity of end milling cutter. ......

In recent years, 3D printing technology has developed very rapidly and has been widely used in many fields of social life. In the construction field, 3D printing technology is more convenient, simple and fast. It can use simple and real materials to quickly build and shape entities. For finished products, it can intuitively reflect the structure, size and other relevant characteristics of buildings, 3D printed building model has a good development prospect in the future development. Here’s everything about 3D pri......

Nylon is the earliest man-made material and one of the most widely used plastics. It covers almost all aspects of life. From wear to use, it is a material with comprehensive properties. Nylon itself is a semi crystalline, thermoplastic material with low melting point and good fluidity, making nylon an ideal 3D printing material. Nylon is mainly divided into eight types: PA6, PA66, PA46, pa69, PA610, pa612, PA11 and PA12. At present, PA12 is the main nylon that can be 3D printed on the market, and PA11 and PA6 are......

After the tool is broken, it may be unable to continue to use in serious cases, resulting in scrapping. Then how do you know when tool breakage or tool chipping occurs? In this article, we’ll introduce the types, causes and solutions for different forms of cutting tool breakage. Types of Cutting ......

Metal cutting machine tools provide a great platform and guarantee for mechanical manufacturing. Good cutting tools should have high hardness and flexibility, especially with the application of high-speed machining technology, dry cutting, and other technologies, the requirements for cutting tools are becoming higher and higher. In fact, there are five kinds of commonly used materials for cutting tools on CNC machine tools. These five materials basically have the characteristics of high hardness, high wear resis......

At present, there are two kinds of nylon materials for 3D printing in the market. One is SLS nylon based on SLS 3D printing, and the other is HP nylon based on HP MJF. What are the differences and connections between these two mainstream nylon and mainstream 3D printing functional plastics? SLS Nylon Vs MJF Nylon For 3D Printing ......

Flanges are a type of commonly used parts in piping, that come in various designs and forms to suit different applications. In this guide, we’ll get into some basics of flanges, featuring the definition, uses, types, important sizes, and more. What is a Flange? ......

The strength grade of the bolt is divided according to the hardness, force, and yield of bolt raw materials. For fastening bolts used in different products and applications, bolts of different grades are required to suit the uses. Bolt strength can be divided into ordinary grade and high strength grade. In this article, we’ll introduce the bolt grades system, the meaning of the bolt head markings grade, you can also check out the metric bolt grades chart. ......
