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

Precautions regarding CNC machined ultra-precision copper electrodes

Many would say that when it comes to ultra-precision electrode machining, it’s very simple. Machines are often bought, tools are used correctly, materials are used well, machining techniques are sophisticated, lower knives are used less, and feed rates are slower. Ultra-precision electrode machining is absolutely not that simple, there are more requirements, and there are more things to watch out for. Share a practical analysis of PTJ Cnc Machining plant. Ultra-precision electrode programming considerations and machining requirements, we hope everyone will like it!

  • 1. Each part of the electrode must be fully engraved with the model number, part number, plate number, gap, position number, and manufacturer.Example 1: 1202B39C51-103A -0.05mm JLS (small fixture);Example 2: 1202B39C51-104C -0.05mm E JLS (Large jig)
  • 2. Electrode copper material must be machined according to the requirements of the list and NC machining program. (Red copper / alloy copper is clearly visible and alloy copper is sprayed with blue paint)
    3. Processing quantity, version number, and copper / alloy copper confirmation are included in the processing list.
  • 4, each part of electrode machining must depend on whether more spark space is needed for the program list note bar provided by the customer. An additional 0.02 / S spark position is required for the entire adhesive position using the “SPI” letter on the program sheet.
  • 5. There is no spark position on the Z axis. The requirement for ultra-precision electrodes is that the base surface follow the spark position. The spark level at the datum level is -0.10 / S or -0.05 / S in the spark gap of the machining list. No need to add sparks to the program sheet.
  • 6, programmers need to be careful. Each electrode of the ultra-precision electrode requires a three-dimensional measurement. When creating the tool path, it is necessary to consider that the treated electrode has no or minimal burrs and that the number of burrs is accurate. Reasonable tools should be selected according to the different shape of each electrode and deburring tool paths should be added when needed.
  • 7.ultra-precision electrodes require three-dimensional measurement. Since quality needs to be tested with the actual size of the processed 3D drawing, the programmer should place a 3D offset in the “CS” folder for testing depending on the spark position of each electrode during programming. And the electrode 3D should be marked with a spark. Also, the layer must specify the spark position and the original “YS”, and the original file must be saved to the file for inspection.
  • 8. Ultra-precision electrodes have dimensional tolerances of 0.01 and 0.02. To ensure tool loss tolerance, flat bottom knives are placed at 0.007, round nose knives are placed at 0.008, and ball cutters are placed at 0.008.
