What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Do you know the machine tool structure in slow wire processing?

 With the continuous development of society, the mechanical processing technology of all walks of life in China has been continuously improved. According to people’s needs and market needs, today’s processing technology has become more and more mature. In recent years, slow-moving wire processing has developed rapidly. It has spread throughout our lives in less than a few years and has brought great help to our production. Slow wire processing is a kind of workpiece cutting. The process is very delicate and the process flow is various. The use not only brings extreme products to the product. With the great convenience, people are more at ease in application and will not cause sparks to affect us. Therefore, for slow-moving wire processing, how much do you know about the structure of the machine tool?

For slow-moving wire processing, this is a relatively complicated process. In order to make it more refined and excellent, we must first know its process and machine structure so that it can function better in the future. We help produce our products. Wire walking is a processing machine tool that uses continuously moving fine metal wires as electrodes to perform pulse spark discharge erosion on the workpiece and cut into shape.

The main body of slow wire processing

  • 1. There are guide rails on the fuselage, using high hardness and wear-resistant materials, and manual hydraulic lubricating oil is added, and the oil pipe flows to each guide rail to achieve lubrication. To reduce the influence of friction coefficient, there are two for each axis. There are also machine tools that use aerostatic guide rails. The friction coefficient of the guide rail is close to zero.
  • 2. The screw adopts spiral displacement, which is determined by the servo speed motor. At present, the minimum movement of a manual single step is 0.001mm. The length of the screw determines the movable range of the machine tool. The screw gap can be measured and corrected by modifying the system parameters. The screw forms a shaft.
  • 3. Secondly, regarding the servo motor, the speed of the servo motor depends on the voltage level selected by the main board of the servo box. The minimum step distance of the motor is the displacement equivalent of 0.0001MM, and each axis has it.
  • 4. After the limit switch (closed switch), the limit switch is set at the left and right ends of the screw displacement range, that is, the actual moving range of the screw. When the machine tool moves to the limit switch is closed, the electrical signal is input to the main board and the output signal of the main board Stop the operation of the servo motor, there are two for each axis.
  • 5. The deceleration switch (close switch) is set in the limit switch. When the screw rod moves to the point where the limit deceleration switch is closed, the electrical signal is input to the main board, and the main board output signal reduces the speed of the servo motor. Each axis has two No. The closing switch is set in the limit switch. When the screw rod displacement is close to the limit deceleration switch, we must master the material selection and structure, and the application quality is good. The subsequent operations can work better and produce better product.
