Working principle of slow wire processing

 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 better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

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 the sales department: make statistics on the tool life data.
  • 2. The sales (marketing) department is responsible for the information reception of scrap molds and customers, and the transmission of internal information.
  • 3. The marketing department is responsible for applying to customers for reopening of mold funds for molds that have exceeded the specified service life.
  • 4. The production department is responsible for the storage and maintenance of the company's molds; responsible for the current status of the molds, and those who meet one of the conditions in the definition of scrap can submit scrap applications; responsible for taking pictures of scrapped molds and collecting evidence; responsible for handing over scrapped molds and customer documents and customers receiving scrapped molds Take pictures of the scene for evidence.
  • 5. Responsibilities of the engineering department. The engineering department evaluates the metal stamping dies that need to be scrapped due to other reasons because the mold has not reached the end of its service life, and determines whether it needs to be reopened.
