How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

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

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Plastic materials and their characteristics

      Plastic materials refer to materials that use polymer synthetic resin as the main component, have plasticity and fluidity at a certain temperature and pressure, can be molded into a certain shape, and keep the shape unchanged under certain conditions. Commonly used plastic materials are divided into thermosetting plastic materials and thermoplastic plastic materials. Thermosetting plastic materials are characterized by being able to solidify into insoluble materials under heat or other conditions. Thermoplastic materials are characterized by repeated heating to soften or cooling to solidify within a specific temperature range. In terms of performance, plastic machining service have the advantages of light weight, good strength, corrosion resistance, good insulation, easy coloring, products can be processed into any shape, high production efficiency, and low price.

      The versatility of the application of plastic materials is inseparable from its own characteristics. The composition characteristics of plastic materials are introduced below.

(1) Molecular structure of plastic materials

The main component of plastic machining  is resin. There are two types of resin, natural resin and synthetic resin.



(2) Composition of plastic materials

Resin: The main function is to bond other components of the plastic material and determine the main properties of the plastic material, such as mechanical, physical, electrical, and chemical properties. The proportion of resin in plastic materials is generally 40% to 65%.

Filler: also known as filler. Correct choice of filler can improve the performance of the plastic material and expand its scope of use.

Plasticizer: Some resins have very little plasticity and poor flexibility. In order to reduce the melt viscosity and melting temperature of the resin, improve its molding processing performance, improve the flexibility, elasticity and other necessary properties of plastic materials, usually Add a non-volatile high-boiling organic compound that is compatible with the resin. Such substances are called plasticizers.

Coloring agent: also known as coloring material, mainly for aesthetics and decoration, including paint part.

Stabilizer: Any substance that can delay the deterioration of plastic materials is called stabilizer, light stabilizer, heat stabilizer and antioxidant.

Lubricant: improve the fluidity of plastic material melt, reduce or avoid friction and adhesion to equipment or molds, and improve the surface finish of Plastic Machining Parts.
