This paper introduces what is a hard-to-cut material, factors affecting the machinability of materials, and cutting characteristics of hard-to-cut materials. The basic concept of improving the machinability of hard-to-cut materials. 1 What is a hard-to-cut material? It is a material with poor machinability. General material performance greater than or less than this indicator (hb>;250, σb>;1000mpa, δ>;30%, ak>;100 mpa, k<41.8w/m-k) of more than one, are difficult to cut materials. It can also be measured by the phenomena in the cutting process (cutting force, cutting heat, tool wear and tool durability, machined surface quality and chip control, etc.). 2 factors affecting the

The feasibility of using carbon steel depends on whether its mechanical properties (such as tensile strength, yield strength, fatigue strength, impact resistance, and required heat treatment) are suitable for making a certain part. If the properties of carbon steel can meet the requirements of a part, most users will choose carbon steel because it is less expensive than other steels. The purpose of this paper is to help users who machine carbon steel parts to understand the composition of various carbon steel grades to improve the efficiency of turning operations; it also gives cutting speed parameters related to depth of

Popular materials chosen by precision machining service providers High precision CNC precision machined parts can be made from a variety of materials, as listed below. Aluminum. Considered exotic in manufacturing, aluminum is probably the most widely used CNC milling material. The ability to machine faster than other materials makes aluminum a more useful material for CNC machining. Because it is lightweight, non-magnetic, corrosion-resistant and inexpensive, aluminum is widely used in the production of aircraft components, automotive parts, bicycle frames and food containers. Stainless Steel. Stainless steel alloys are unaffected by most stains and rusts. The material is prized for its

Until the 1950s, CNC machines operated primarily on data derived from punched cards, which were still largely manufactured through painstaking manual processes. The turning point in the evolution to CNC was when the cards were replaced by computer controls, which directly reflected the development of computer technology, as well as computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. Machining became one of the first applications of modern computer technology. Although the Analytical Engine developed by Charles Babbage in the mid-1800s is considered the first computer in the modern sense, the Massachusetts Institute of Technology’s (MIT) real-time computer Whirlwind I (also

Ceramic parts have the characteristics of extremely high hardness and good wear resistance and corrosion resistance. What are the commonly used china cnc machining methods for ceramic parts? Next, Kezhong Ceramics will introduce to you. 1. Turning of ceramic materials The turning process is mainly to use diamond tools to cut ceramic materials with high hardness and high wear resistance. It is difficult to produce smooth cutting edges with polycrystalline diamond tools. Generally, it is only used for rough machining. When fine turning of ceramic parts, use natural single The crystalline diamond tool adopts the micro-cutting method when cutting. Due

ESD (electrostatic discharge) is an abbreviation for electrostatic discharge. Non-conductive objects generate static charges by friction, heating, or contact with other electrostatically charged objects. When an electrostatic charge accumulates a gradient (electric field gradient) in a particular electric field, it will lead to an arc, or attractive force (mechanical attraction). The phenomenon in which energy is released by an electric arc due to the accumulation of static electricity in a non-conductor is called ESD. Electrostatic protection (ESD) of sheet metal case 1-1 Factors that affect the charging of objects Important factors Conductor — Charges are easily neutralized and do not

Reasonable choice of tool material is an important condition for high efficiency machining of stainless steel. According to the cutting properties of stainless steel, the tool material is required to have good heat resistance, high wear resistance, and a small affinity with stainless steel. Currently commonly used tool materials are high speed steel and cemented carbide. High Speed ​​Steel Selection High speed steel is mainly used in the manufacture of complex multi-blade tools such as milling cutters, drills, taps and broaches. Regular high-speed steel W18Cr4V tools are less durable and do not meet your needs. Good results are obtained by

Nowadays, more and more beryllium copper mold materials have been used in the manufacture of plastic molds, and there is a rising trend. What is the reason for this phenomenon? Let me learn about the use of beryllium copper in plastic molds with the editor, and why.

Compared with conventional CNC titanium machining processes, the outstanding advantages of turning-milling combined machining are mainly manifested in the following aspects:

Metal materials 1. Cast iron Cast iron and steel are both iron-carbon alloys. The main difference between them lies in the carbon content. Iron-carbon alloys with a carbon content of less than 2% are called steel, and those with a carbon content of more than 2% are called cast iron. 2. Steel Compared with cast iron, steel has high strength, toughness and plasticity, and heat treatment can be used to improve its mechanical properties and processing properties. The blank of steel machining parts can be obtained by forging, stamping, welding or casting, so its application is extremely wide. According to

Precision parts processing is a complex and rigorous process, which is composed of each step-by-step process. So what are the specific points of precision parts processing? The production process of a machine refers to the entire process of making a product from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of raw materials, production preparation, blank cnc machining, parts processing and heat treatment, product assembly, and Contents such as debugging, painting and packaging. The content of the production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize

Plastic molds have poor fluidity of PC/ABS materials at lower injection temperatures, and the injection molded products have greater internal stress. The stress is released during the coarsening process, and the product is not uniformly etched, which leads to poor electroplating appearance and electroplating bonding. When poor conditions occur, PTJ Plastic Mould Factory will teach you a lesson-molding temperature and electroplating. The higher injection temperature of the plastic mold needs to reduce the residual internal stress of the product, thereby improving the electroplating performance of the material. According to the effective data of PTJ, compared with the product with an
