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

Operation process and specifications of precision metal processing

Precision metal machining can be cut as required, and then some small parts or CNC machining can be cut. The precision metal container must be cut with a punch first, then welded, and the parts are polished and sprayed. The surface of small parts that need to be reminded also needs to be polished to electroplating or spraying. Batch machining of precision metal parts is quite common, so the manufacturing method and cycle of precision metal machining are different from the operating specifications and processes of ordinary product machining. Let me explain to you the technical operation specifications of precision metal machining.



Precision metal machining technology

  • 1. There is a big uncertainty in machining. There can be multiple processes for a part or product design. There are many types of machine learning equipment and tooling fixtures required for the production management process.
  • 2. Hardware manufacturing is mainly distributed machining. The quality and productivity of products depend to a large extent on the technical level of workers, while the degree of automation is mainly at the unit level, such as CNC machine tools and flexible manufacturing systems.
  • 3. Hardware machining product parts can generally be made by combining network self-made and external machining technology. For example, special treatment processes such as electroplating, sandblasting, oxidation, silk screen laser engraving, etc. will be entrusted to external manufacturers for machining.
  • 4. More parts are needed, and the workshop often needs to fill a lot of materials. You will see a "line-shaped" production order, such as process management, and you also need to fill in a large number of process transfer orders.

The operation of precision metal machining technology is standardized:

  • 1. Product machining. Operators should maintain the correct posture and have sufficient energy to cope. If they are unwell, they must leave the work position immediately for personal safety and report to the workshop supervisor or superior. The operation must be concentrated, chatting is strictly prohibited, mutual cooperation, the operator should not be in a state of irritability, fatigue, for personal safety, avoid accidents and ensure safe operation. All employees check whether their clothing meets the job requirements before entering the job. Don't wear slippers, high heels and safety clothing. Wear a hard hat for long hair.
  • 2. Before mechanical design work, check whether the control part is filled with lubricating oil, then start and check whether the clutch and brake are normal, and run the machine idling for 1-3 minutes. Operation is strictly prohibited when the machine is faulty.
