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
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

The translation of cnc is called computer numerical control. Abbreviated as CNC in English. The automatic machine tool is digitally controlled by a computer. CNC includes CNC lathes, machining centers, CNC wire cutting, CNC punching machines, CNC laser cutting machines, etc. Many people mistakenly think that CNC is a CNC machining center, but this is actually wrong. So what is a cnc machining center?
The CNC machining center is a CNC boring and milling machine that integrates the functions of a CNC milling machine, a CNC boring machine, and a CNC drilling machine. It is equipped with a tool magazine and an automatic tool changer.
The CNC machining center is a highly automated multifunctional Cnc Machine tool with a tool magazine and automatic tool changer. After the workpiece is clamped on the machining center once, it can complete multiple processes with more than two surfaces, and has a variety of tool change or tool selection functions, which greatly improves the production efficiency.
Many people say that CNC machining centers and CNC machining centers are the same, but in fact they are different. What is the specific difference?
The CNC machining center is actually an upgraded version of the CNC milling machine. Compared with manual machining, CNC machining center has great advantages. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce complex shapes that cannot be completed by manual machining. section.
CNC machining center is an efficient automatic machine tool that is composed of mechanical equipment and numerical control system, suitable for processing complex parts. Its comprehensive processing ability is strong, and more processing contents can be completed in one clamping of the workpiece. The CNC machining center is suitable for machining shaft parts, and the CNC machining center is suitable for adding box-shaped parts with more complicated parts geometry. Of course, CNC machining centers generally only have two axes and two linkage devices, while CNC machining centers have at least three axes. .
Materials that can be processed by CNC machining center:
Including pure metal materials, alloy materials, plastic materials, wood, etc.
Common CNC machining machine tools
Lathes, milling machines, drilling machines, etc. According to different processing complexity, it can be divided into three-axis, four-axis, five-axis machines, etc.,
effect:
The main purpose of CNC machining is to remove the excess parts of the raw materials to make them have appropriate shapes, such as circles, rectangles, etc. In the traditional method, these machines are operated by the operators of experts who operate these machines. Most jobs require accurate processing, and operators should have sufficient professional capabilities to perform precision processing.
Convenience:
In CNC machine tools, the role of the operator is minimized. The operator must only enter the instruction program in the computer, load the required tools into the machine, and the other work is done automatically by the computer. The computer instructs the machine tool to perform various machining operations according to the instruction program fed by the operator.
CNC machining center can also be understood as the following meaning: So, what does cnc machining center mean? Actually, it is CNC milling machine. It is called “CNC machining center” in Guangzhou, Jiangsu, Zhejiang and Shanghai. It is an automatic machine tool equipped with a program control system. (Numerical control machine tool) is a computer numerically controlled machine tool. (Computer numerical control) abbreviation, is an automatic machine tool controlled by a program. The control system can logically process programs with control codes or other symbolic instructions, and decode them by a computer, so that the machine tool can operate and process parts. The rough material is processed into semi-finished finished parts by cutting tools. CNC Machining (CNC Machining) CNC Machining refers to processing with CNC machining tools.
CNC index-controlled machine tools are programmed and controlled by CNC machining languages, usually G codes. The CNC machining G code language tells the Cartesian position coordinates of the machining tool of the CNC machine tool, and controls the feed speed and spindle speed of the tool, as well as the tool changer, coolant and other functions. Compared with manual machining, CNC machining has great advantages. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual machining. Numerical control machining technology is now widely promoted. Most machining workshops have NC machining capabilities. The more common CNC machining methods in typical machining workshops include CNC milling, CNC turning, and CNC EDM wire cutting (electric discharge wire cutting).
The tools for CNC milling are called CNC milling machines or CNC machining centers. The lathe that performs numerical control turning processing is called a numerical control turning center. CNC machining G code can be programmed manually, but usually the machining workshop uses CAM (computer aided manufacturing) software to automatically read CAD (computer aided design) files and generate G code programs to control CNC machine tools.
