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 are the selection of positioning datums for precision parts processing?

 The production of nuts, studs, and stainless steel materials is becoming more and more intelligent now. When producing these equipment accessories, choose accurate and high-standard equipment. With the advancement of science and technology, intelligent and automated instruments , The equipment has a very fast speed in the circulation of various fields, which brings challenges and opportunities in a new stage to the development of precision parts. This paper analyzes the market demand and process concept of precision parts, and combines the skills and problems in actual processing (with the scope of clamp work as the limit), and explores the solutions and skills of related problems in precision parts processing in order to improve precision parts. Improve the quality of market supply and demand, and promote the development of a technological and intelligent society.


In actual production, the structure of each part may be very different, which also greatly increases the difficulty of processing. However, if you observe carefully, you can find that the basic geometric composition of parts is nothing more than outer circle, inner hole, plane, thread, tooth surface, curved surface, etc., so as long as the processing of these shapes is mastered, the difficulty of precision parts processing is also Can be greatly reduced.

In the process of precision parts processing, whether the selection of positioning reference is reasonable or not determines the quality of the parts, and it is very important to ensure the dimensional accuracy and mutual position accuracy of the parts, as well as the arrangement of the processing sequence between the surfaces of the parts. Big impact. If the fixture is used to install the workpiece, the choice of positioning datum will also affect the complexity of the fixture structure. Therefore, the choice of positioning datum is a very important process problem in precision parts processing.

Nowadays, mechanized and automated production has been achieved in part of the production process. Then the automated processing system can automatically monitor its operating status, and automatically adjust its parameters when subjected to external interference or internal excitation to achieve the best state and availability. Self-organization ability, so as to greatly improve the efficiency of rough and finishing processing under the premise of ensuring processing accuracy.
