The spindle taper holes in the machining center are generally divided into two categories, a general-purpose system with a taper of 7:24 and a 1:10 HSK vacuum system. 1. Universal shanks with a 7:24 taper usually have five standards and specifications: NT (traditional) referred to as NT or ST) DIN 69871 (German standard) (JT, DIN, DAT or DV for short) IS0 7388/1 (International Standard) (referred to as IV or IT) MAS BT (Japanese Standard) (BT) ANSI/ASME (US Standard) (CAT) ★NT type shank German standard is DIN 2080, which is used to tighten the shank by the tie rod on the traditional type machine tool, also known as ST in China; The other four shanks are used to tighten the shank on the machining center through the shank at the end of the shank. At present, the most commonly used in the country are the DIN 69871 (ie JT) and MAS BT type. The DIN 69871 tool holder can be mounted on DIN 69871 and ANSI/ASME spindle taper machines. The IS0 7388/1 tool holder can be mounted on DIN 69871, IS0 7388/1 and ANSI/ASME spindle tapers. On the machine, so the shank of IS0 7388/1 is the best in terms of versatility. ★The rivet has three key parameters: θ angle, length l and thread G There are several cases regarding the θ angle of the shank pull: 1, MAS BT (Japanese standard) handle rivet angle θ angle of 45 °, 60 ° and 90 °, commonly used 45 ° and 60 °; 2, DIN 69871 shank pull pin (commonly known as DIN 69872-40/50) θ angle is only 75 °; 3, IS0 7388/1 handle shank (commonly known as IS0 7388/2-40/50) θ angle has 45 ° and 75 ° points; 4. ANSI/ASME (American Standard) shank θ angles are 45°, 60° and 90°. Regarding the thread G of the shank rivet, except for the ANSI/ASME (American Standard) shank rivet, there are three types of metric thread. The other three use metric thread. The 40# shank rivet usually uses M16 thread, 50# knives. The shank pull is usually M24 threaded. The 7:24 shank has: JT series holder (ISO, German DIN standard, Chinese GB standard) BT series holder (Japan MAS standard) JT-WA series holder (German VDI standard) JT-U series holder (American ANSI standard) CAT Series Holder (American ANSI Standard - Caterpillar) ST series tool holder (China GB standard) SK series holder (German DIN standard) Second, 1:10 HSK vacuum shank The German standard for HSK vacuum holders is DIN69873. There are six standards and specifications, namely HSK-A, HSK-B, HSK-C, HSK-D, HSK-E and HSK-F. There are three commonly used: HSK-A. (with internal cold automatic tool change), HSK-C (with internal cold manual tool change) and HSK-E (with internal cooling automatic tool change, high speed type). The 7:24 universal tool holder is positioned by the 7:24 taper surface of the tool holder and the 7:24 taper surface of the machine tool spindle hole. It has limitations in high speed machining, joint rigidity and coincidence accuracy. The HSK vacuum shank is elastically deformed by the shank, not only the 1:10 taper surface of the shank is in contact with the 1:10 taper surface of the machine tool spindle hole, but also the flange surface of the shank is in close contact with the main shaft surface. The surface contact system is superior to the 7:24 universal tool holder for high speed machining, joint rigidity and coincidence accuracy. Automatic tool change without robot. BT50 holder and JT50 holder can be interchanged (1) DIN 2080 (NT or ST for short) DIN 2080 is the German standard, the international standard ISO 2583. It is what we usually call the NT type shank. It cannot be loaded by the robot of the machine tool. (2) DIN 69871 (JT, DIN, DAT or DV for short) About NT NT is just a popular name, and it has a metric system. The general devil's NT points are NT(U) and NT(m). DIN2080 is metric. The domestic ST standard is based on the DIN 2080 standard, so ST, NT (m) and DIN 2080, can be used universally. The standard number of JT is: GB10944, which is based on DIN69871/1 and is common to ISO7388/2. DIN69871 is generally referred to as the German: SK three standard parameters are universal. So some people call JT, ISO, DIN, SK, as for DV, DAT, those called the law is the name of some companies.

First, the requirement of the tool can serve as <br> <br> lathe coarse, fine turning. In order to make the rough car can eat big knife and big knife, the rough car tool is required to have high strength and good durability; the fine car first guarantees the machining precision, so the tool requires high precision and good durability. In order to reduce the tool change time and facilitate the tool setting, the machine clamp should be used as much as possible. Use the machine clamp to prepare conditions for automatic tool setting. If it is only an initiative to use a machine clamp on a conventional lathe, then a machine clamp on a CNC lathe is a requirement. The cutter body of the machine clamp requires high manufacturing precision, and the method of clamping the blade should be selected reasonably. Since the machine clamp is mounted on a CNC lathe, generally no spacer adjustment is made, so the accuracy of the tip height should be guaranteed during manufacture. For the inner diameter arbor with a large ratio of long diameter, it is preferable to have an anti-vibration structure. The coolant of the inner diameter knife is preferably introduced into the cutter body first and then ejected from the vicinity of the cutter head. For inserts, coated carbide inserts should be used in most cases. The coating exhibits its superiority at higher cutting speeds (>100 m/min). The cutting speed of a general lathe is generally not good, so the cemented carbide insert used may not be coated. Blade coatings cost less than double the cost, while durability can be more than doubled when used on CNC lathes. The use of coated inserts on CNC lathes increases the cutting speed and thus increases machining efficiency. The coating material generally has titanium carbide, titanium nitride and aluminum oxide, and the same blade can also be coated with several layers of different materials to form a composite coating. CNC lathes have higher requirements on the chipbreaker of the blade. The reason is simple: CNC lathes are highly automated, and cutting is often done in a closed environment, so it is difficult to manually dispose of large amounts of chips during turning. If the chip is not broken well, it will wrap around the bit, which can both crush the blade and strain the cutting surface. Carbide inserts for general lathes are typically two-dimensional chipbreakers, while CNC turning inserts often use three-dimensional chipbreakers. Three-dimensional chipbreakers come in many forms and are typically shaped into several standards in blade manufacturing plants. Its common feature is good chip breaking performance and wide chip breaking range. For the specific material parts, after the cutting parameters are set, pay attention to the slot shape of the blade. Some theoretical discussions can be made during the selection process, but more importantly, the actual cutting test is carried out. In some cases, the cutting parameters can also be modified based on the groove pattern of the existing blade. There is no doubt that the blade is required to have high durability. CNC lathes also require consistent blade durability for easy tool life management. When using tool life management, blade durability is set based on the lowest durability blade in the batch. In this case, the consistency of blade durability is even more important than its average life. As for the accuracy, the precision consistency between the blades is also required. Second, the requirements for the knife holder (clip) Knives (blades) are rarely mounted directly on the tool holder of a CNC lathe. They are usually transitioned between the holders (also called tool holders). The structure of the tool holder mainly depends on the shape of the tool body, the shape of the tool holder and the arrangement of the tool holder to the main shaft. Nowadays, there are many kinds of tool holders, and the production plants are doing their own thing, and the degree of standardization is very low. The standardization degree of the machine clamp body is relatively high, so there are not many types and specifications; there are only a few ways to arrange the tool holder to the machine tool spindle; only the shape of the tool holder (mainly refers to the part connected with the tool holder) Too many types. When selecting users, users should minimize the types and types to facilitate management.

The National Day of the People's Republic of China is also known as the National Day, National Day, China National Day, National Day Golden Week. The Central People's Government announced that since 1950, on October 1 of each year, the day of the founding of the People's Republic of China, the National Day. The National Day of the People's Republic of China is a symbol of the country, which has emerged along with the founding of the new China and has become particularly important. It has become a symbol of an independent country, reflecting the country and polity of our country. National Day is a new and universal form of festival that carries the function of reflecting the cohesiveness of our country and nation. At the same time, the large-scale celebrations on National Day are also a concrete manifestation of the government's mobilization and appeal. It has three basic characteristics of showing the strength of the country, enhancing national confidence, embodying cohesiveness and exerting appeal.

Historical origin This is a traditional Chinese festival. On the 15th day of the lunar calendar, this day has the custom of enjoying the moon and eating moon cakes. Mid-Autumn Festival is a traditional Chinese festival. According to the records of historical records, the word "Mid-Autumn Festival" first appeared in the book "Zhou Li". By the time of the Wei and Jin Dynasties, there were records of "the cattle in the Shangshang Book, the Mid-Autumn Festival and the Weijiang River." It was not until the early Tang Dynasty that the Mid-Autumn Festival became a fixed holiday. "Tang Shu Tai Zong Ji" records "August 15 Mid-Autumn Festival". The prevalence of the Mid-Autumn Festival began in the Song Dynasty. By the time of the Ming and Qing Dynasties, it had become one of the main festivals in China. This is also the second largest traditional festival in China after the Spring Festival. According to the Chinese calendar, the lunar calendar is in the middle of autumn, the second month of autumn, called "Zhongqiu", and August 15th is in "Zhongqiu", so it is called "Mid-Autumn Festival". There are many other names for the Mid-Autumn Festival: because the festival is on August 15th, it is called "August Festival" and "August and a half". Because the main activities of the Mid-Autumn Festival are all around the "month", it is also known as the "Monthly Festival". "Month of the Moon"; the Mid-Autumn Festival is full of moons, symbolizing reunion, and is therefore called "Reunion Festival". In the Tang Dynasty, the Mid-Autumn Festival was also known as the "Terminal Moon." The record of the "Reunion Festival" was first seen in the Ming Dynasty. "West Lake Tour Zhiyu" said: "August 15 is called Mid-Autumn Festival, the folks send the moon cakes, take the meaning of reunion." "The Emperor Jingjing Scenery" also said: "August 15th Festival, the cake will be round, the melons will be wrong, and the petals will be carved like lotus....There is a woman who is returning to the house, and will return to the husband's house. Festival also." In the Mid-Autumn Festival, most of China also has the custom of branding [reunion", which is to make a small pie that symbolizes reunion and mooncakes. The cake contains sugar, sesame, sweet-scented osmanthus and vegetables, and the moon, laurel, rabbit and other patterns are pressed outside. . After the festival month, the elders at home will divide the cake into pieces according to the number of people, one for each person. If someone is not at home, they will leave a copy for the family reunion.

Chuck claw is also a part of the chuck. The use of the chuck is very extensive, it can play a role in improving efficiency, and can reduce the labor intensity, etc., and the simple structure and the convenience of use have brought us numerous Convenience, then what are the issues that need to be paid attention when the chuck jaws are used? This is where we need to know. We must pay attention to the problem and we must achieve better results. During the use of the chuck jaws, the first point of attention is to maintain the cleanliness of the workpiece surface. Of course, the degree of cleanliness of the clamping arc of the jaws should also be ensured. If the degree of cleanliness is not guaranteed, it may be during the use process. There will be situations such as excessive standards, which is not good for our normal use, so this must be handled well at work. The second point in the process of using the chuck jaws is to replace the jaws. Do not install the wrong order. Don't think that there is no big relationship between the wrong order. If the order is wrong, then the use effect is not good. On the other hand, it is possible that there will be a situation that exceeds the standard, so the grasp of accuracy, etc. is naturally not the best. Of course, it does not bring us greater convenience. The third point of attention is that when it is used, there should be no unstable positioning. Positioning instability will inevitably have some impact on production and processing. Note that the fourth point is to carry out some checks frequently. If the claws have problems, they must be timely. Only in this way can we bring the best results to us. If we ignore them for a long time, then naturally there will be many unqualified cases.

Definition of heat treatment: A process in which the solid metal is heated, insulated and cooled in a suitable manner to obtain the desired microstructure and properties. The heat treatment of steel not only improves its structure and properties, but also improves its process ability. More important are the key processes that give the final performance of the part. Many parts can not be used directly after being shaped, but must be heat treated before they can be used. Electroplating: It is the process of electroplating a thin layer of other metals or alloys on the surface of certain metals. It is a process of using electrolysis to attach a metal film to the surface of metal or other materials to prevent corrosion and improve resistance. Grinding, conductive, reflective, and aesthetic enhancement. During electroplating, a plated metal or other insoluble material is used as an anode, and a workpiece to be plated is used as a cathode. The cation of the plated metal is reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the coating uniform and firm, it is necessary to use a solution containing a plating metal cation as a plating solution in order to maintain the concentration of the plating metal cation unchanged. Non-metallic materials are not electrically conductive and therefore cannot be plated directly. To perform electroplating, it must be made conductive. For this purpose, a conductive film is applied, i.e., the surface of the non-metallic material is subjected to a rigorous treatment, physically or chemically coated with a conductive material, and then electroplated in the usual manner. The metal is plated and deposited on the surface of the non-metal material through the intermediate action of the conductive film. Decorative: Plastic plating has played a huge role in both economic benefits and external appearance. It is widely used in modern automobiles, cruise ships, high-speed trains, and airplanes. The architectural decoration is mainly used for building metal emblems, large signboards, wall reliefs, chandeliers, and pillars. In addition household products and electronic products, but also can not be separated from plastic plating, such as mobile phones, MP3, U disk, laptop computers and other shells, are using plastic plating accessories.
