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 specific reasons for the popularity of five-axis machining of plastic parts?

Five-axis machining of plastic parts is a very advanced and exquisite machining technology. Nowadays, products in many fields need to use very accurate parts, such as aerospace, aviation, etc. The products of these industries cannot have the slightest error. In order to ensure that the size of the part does not have a large error, it is necessary to use a five-axis machining process. Let’s take a look at the specific reasons for the popularity of five-axis machining of plastic parts.

1. It can process parts with difficult shapes

Many parts used in products have extremely strict technical standards. Some parts are very complicated in shape and structure, and some parts have very thin wall thickness. It is difficult to complete the machining of these parts by using traditional machining methods even if they are forced. There are also various problems or defects in machining. However, five-axis machining will not have such a problem, whether it is a complex structure shape or a thin-walled part, it can meet the corresponding technical standards.

2. The production process chain can be shortened

For the production enterprise, if the process of production management can be simplified, the corresponding production cost can be reduced, which is beneficial to the operation of the enterprise. The use of five-axis machining technology can greatly shorten the formal production process chain, thereby simplifying the production management and planning and scheduling of the enterprise. Moreover, the more complex the processed workpiece, the more obvious its advantages compared to the traditional process.

3. Can shorten the new product development cycle

For some high-demand companies, some new product parts and forming molds have complex shapes and high accuracy requirements. Five-axis machining has high flexibility, high precision, high integration and complete machining capabilities, so it can It can well solve the accuracy and cycle problems of complex parts machining in the process of new product development.

Because the cost-effective five-axis machining of plastic parts can not only process parts that are difficult to shape and structure, but also greatly shorten the production process chain, greatly shorten the research and development cycle and improve the success rate of new products, so in this era , Five-axis machining is very popular among machining companies.
