Wood products processing refers to the processing process of changing the shape, size and surface quality of wood by destroying the connection between wood fibers through cutters. The machinery for processing wood products is called woodworking machinery. Woodworking machinery is widely used in construction, furniture, factory wood mold processing and home decoration industries. There are many kinds of woodworking machines, which can be divided into woodworking sawing machine, planer, milling machine, drilling machine, lathe and sanding machine according to their working principle, scope of application and performance structure. Woodworking machinery and equipment belong to equipment with high operational risk. Since…

With the higher and higher requirements of hardness in modern engineering material processing, the hardness of tools is also higher and higher, and more superhard tools are applied. Superhard tools are mainly used for cutting hardened steel, including carbon tool steel, alloy tool steel, high-speed steel, bearing steel, die steel, etc., or cutting various iron-based, nickel based, cobalt based and other thermal spraying (welding) parts. However, cutting different materials will have different superhard tools, so it is very important to understand the classification of superhard tools. Here is a brief introduction for you. (1) PCD metal cutting tool Tool type:…

one Scorched 1. Scorching phenomenon (1) The temperature is too high, or the instrument controlling the temperature is out of order, causing the plastic to scorch due to high temperature. (2) The rubber outlet of the machine head has large smoke, strong irritating smell and crackling sound. (3) Granular scorched matter appears on the plastic surface. (4) There are continuous air holes at the glue joint. 2. Causes of scorching (1) Super high temperature control causes scorching of plastics. (2) The screw has been used for a long time without cleaning, and burnt materials are accumulated and extruded with plastic.…

If no measures are taken after the door cover is welded, assembled and adjusted to be qualified, the flatness and clearance of the door cover will be greatly changed under the influence of external force and internal stress release during transportation and coating. This phenomenon is common in the automobile industry, especially the impact on flatness is obvious. In view of this problem, this paper introduces the concept of welding boss applied to the welding spot of the door cover, and proposes a new process method - using the welding boss to realize welding, so as to improve the rigidity…

With the development of microelectronics and computer technology, the development of numerical control technology in China has been promoted. The domestic numerical control system has been successfully developed, which ensures the quality and performance of numerical control machine tools in China. Numerical control machine tools have been widely used in various fields because of their strong adaptability to workpiece modification, high machining accuracy and high productivity. Numerical control technology has been widely used in sheet metal machine tools. It solves the problems of high precision, complex shape and large batch in sheet metal processing. Numerical control sheet metal machine tools…

The combination of laser and welding is a great breakthrough in traditional industry. It not only improves the welding quality, but also shortens the welding cycle. Today, laser welding processing technology has been applied in many industries, the most common being high-tech electronics, automobile manufacturing and precision processing. However, in the field of automobile manufacturing, the application proportion of laser welding is still in the lower middle level. The concept of laser welding is also credited to Volkswagen. In the dazzling automobile market, Volkswagen brand has always been favored for its durability. This is exactly what the traditional welding processing…

All control of the 6-axis industrial robot is completed by a microcomputer. The other is decentralized (level) control, that is, multiple microcomputers are used to share the control of the robot. For example, when the upper and lower level microcomputers are used to jointly complete the control of the robot, the host computer is often used to be responsible for the management, communication, kinematics and dynamics calculation of the system, and send command information to the lower level microcomputers; As a subordinate slave, each joint corresponds to a CPU to perform interpolation operation and servo control processing, realize a given…

As one of the most widely used digital products in modern society, smart phones have become the most essential items in people's daily life. However, the development history of mobile phones is only 44 years, and the popularity of smart phones is only in the last decade. The changes in the shell materials of mobile phones are very significant. From the beginning of plastic to the new generation of materials represented by metal glass today, what is the best material for mobile phones? First, let's sort out the common cell phone shell materials, such as plastic, metal, glass, ceramics, wood,…

As we all know, rare earth has always been China's national defense strategic armament material. At the same time, due to its irreplaceable role in national defense and military weapons and equipment, and its reserves are extremely low, all countries are making long-term reserves. At present, the advanced weapons and equipment of western countries are extremely dependent on China's rare earth materials. The United States, in particular, relies almost entirely on imports from China. Of course, in addition to the military field, these materials are also used in smart phones, global positioning systems, automotive electronic components, computers, computer screens and…

Tool steel is particularly attractive to manufacturers compared to steel. As its name suggests, tool steel is very suitable for making tools. It is a very hard, highly heat-resistant and wear-resistant material, with multiple grades, suitable for various applications. For such a high-quality material, the 3D printing industry certainly has a great demand, as CEO markforge pointed out in a recent interview. Markforge will develop tool steel materials for its metal x 3D printer. It is exciting that nanosteel has taken the lead. Today, the company announced the launch of a new 3D printing tool steel material, which is also…
