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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

What Does the Daily Operation of CNC Machining Attract Attention?

What are the points for attention in daily operation of Cnc Machining?

In the late 1940s, the United States began to study Cnc Machine tools, 1952, the Massachusetts Institute of Technology (MIT) servo laboratory successfully developed the first CNC milling machine, and in 1957 put into use.The first CNC machining center is the first successful development by the United States Carney – Drake Company in 1958.It adds an automatic tool change device on the basis of CNC horizontal boring and milling machine, so as to realize a clamping workpiece can be milling, drilling, boring, hinge and tapping and other processes of centralized processing.This is a major breakthrough in the process of manufacturing technology development, marking the beginning of the era of CNC lathe processing in the manufacturing field.CNC lathe processing is the foundation of modern manufacturing technology, this invention for manufacturing industry, has epoch-making significance and far-reaching influence.The main industrial developed countries in the world attach great importance to the research and development of numerical control lathe processing technology.

CNC machining is generally refers to the processing process of parts on CNC machine tools.CNC machine tool is a computer to control the machine tool, the computer used to control the machine tool, whether it is a special computer, or a general computer are collectively called CNC system.

 

The movement and auxiliary movements of CNC machine tools are controlled by the instructions issued by the numerical control system, and the instructions of the numerical control system are compiled by programmers according to the material of the workpiece, processing requirements, characteristics of the machine tool and the instruction format (numerical control language or symbols) specified by the system.According to the program instruction, the CNC system sends out operation terminations or information to the servo device and other functional parts to control the various movements of the machine tools.The machine stops automatically when the parts are finished.Any numerical control machine tool, in its numerical control system if there is no input program instruction, numerical control machine can not work.The controlled movement of the bed includes the starting and stopping of the machine tool.Spindle start and stop, rotation direction and rotation speed transformation;Direction, speed and mode of feed movement;Tool selection, length and radius compensation;Tool replacement, coolant on and off, etc.

 

The technical procedures of CNC machining are generally the same, but there have been significant changes.A machining method for controlling the displacement of parts and tools with digital information.

CNC machining is an effective way to solve the problems of variable parts variety, small batch, complex shape and high precision, and to realize high efficiency and automatic processing.Machining center originally developed from CNC CNC milling machine processing.
