What is ultra-low temperature processing? Why hasn’t it become popular? In the tool wear mechanism, wear itself is not the only reason for tool failure; high temperature is the real enemy of tools. In conventional wet cutting processes, the main function of cutting fluid is lubrication and/or splashing on the tool and workpiece to remove heat. In low-temperature cutting processes, liquid nitrogen is used as the coolant instead of cutting fluid. The temperature of the coolant poured may be 20°C, while the temperature of liquid nitrogen is -196°C. Such a large temperature difference......

Polysulfone (PSU) is a versatile engineering plastic that has been increasingly adopted across various industries due to its exceptional mechanical, thermal, and chemical properties. This article provides an in-depth look at the properties and applications of PSU plastic, highlighting the PSU machining service at CNCJY and its uses in different fields. What Is PSU Plastic? Polysulfone (PSU) is a high-performance, amber-colored, amorphous polymer that is transparent or semi-transparent. It has excellent mechanical properties, including rigidity, abrasion resistance, and heat resistance,......

Nylon is a type of polyamide, a polymer with repeating units linked by amide bonds. It is characterized by its strength, elasticity, and resistance to abrasion and chemicals. The name “Nylon” is often used to refer to a family of materials, each with a different number designation. These designations refer to the number of carbon atoms in the diamine and dicarboxylic acid monomers used to produce the CNCJY nylon polymer. 5 Types of Nylon Nylon 1,6: This is a relatively rare type of nylon. The numerals “1,6” indicate that it is made from one carbon atom in ......

Brass is a yellow alloy of copper and zinc that is valued for its corrosion resistance, machinability, attractiveness, and ability to be formed or joined. It has many applications in both industrial and decorative products. What Are the Different Types of Brass -Alloy 260 (Cartridge Brass): Has approximately 62% copper and 38% zinc. Commonly used for ammunition cartridge cases and other applications requiring high strength. Also known as Brass 260. -Alloy 280 (Muntz Metal): Composed of approximately 60% copper and 40% zinc. An architectural grade brass known for its corrosion ......

Metalloids, also known as semi-metals, occupy a unique position in the periodic table. They are elements that straddle the line between metals and nonmetals, possessing characteristics of both. This unique group of elements includes boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po). Properties of Metalloids Though the properties of metalloids can vary greatly, there are six key characteristics that most share: 1. Physical Appearance Metalloids generally have the appearance of metals. They are usually shiny, silvery-......

Steel is primarily made of iron and carbon. The process of making steel involves the reduction of iron ore to produce iron, which is then combined with carbon and other elements to create different types of steel. Types & Properties of Steel Steel is an alloy of iron carbon, and sometimes other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. There are many different types of steel, each with unique chemical compositions and properties: 1......

A spring is a mechanical device that stores and releases energy. Springs can be made from a variety of materials, but most commonly they’re made from hardened steel. A spring is typically formed into the shape of a coil to effectively store and release energy. The most fundamental law relating to springs is Hooke’s Law, which states that the force a spring exerts is proportional to its extension. Spring can be tailored by changing the material or geometry of the spring. This allows engineers to design springs for a wide variety of specific applications. Types of Springs: ......
