Working principle of slow wire processing

by
 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...

What are the rules for metal stamping die scrap tube?

by
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...

Introduction of KOVAR parts

by
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...

What is the difference between metal processing and sheet metal processing?

cncmachining December 17, 2020

  • 1. Hardware actually refers to five metal materials: gold, silver, copper, iron, and tin. Hardware is the mother of industry and the foundation of national defense. From the perspective of the nature and use of hardware processing, it should be divided into eight categories: steel materials, non-ferrous metal materials, mechanical parts, transmission equipment, auxiliary supplies, work supplies, construction hardware, and household hardware. Each type of hardware has different uses and functions. , Can be selected according to specific needs.
  • 2. Sheet metal in sheet metal processing refers to the ability to perform data analysis and processing on even-thick plates. Sheet metal processing and hardware processing have important and substantial differences, mainly in production management processes such as shearing, folding, welding, and bonding. The natural resources of hardware include sheet metal and various sheet metal parts.

 What is sheet metal processing?

After understanding hardware processing, what is sheet metal processing? It refers to the key technology mastered by sheet metal technicians, and it is also an important process of sheet metal product forming. Sheet metal processing includes traditional cutting, blanking, bending and other methods and process parameters, including the structure and process parameters of various cold stamping dies, the working principles and operating methods of various equipment, and new stamping processes and new technologies. Parts metal plate processing is called sheet metal processing.

  • 1. Separate procedures are to separate the stamping parts and the blanks along a certain contour line during the stamping process. At the same time, the quality management of the separate sections of the stamping parts must be satisfied with certain requirements. These requirements analysis are all through the previous customers Selected by demand.
  • 2. Sheet metal processing is the same as hardware processing. In the forming process, the stamping blank is formed into the required product shape without damage, and meets the standard requirements.
