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

Five aspects of sheet metal sandblasting applications

Five aspects of sheet metal sandblasting applications

Sheet metal sandblasting uses compressed air as the power to form a high-speed jet beam to spray the spray material on the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. The impact and laser cutting action make the surface of the workpiece obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, thus improving the fatigue resistance of the workpiece and increasing the adhesion between it and the coating, Extends the durability of the coating film, and also facilitates the leveling and decoration of the coating.

There are five main applications of sandblasting:

1. Improve the mechanical properties of the parts After sandblasting, Cnc turnning parts can produce uniform and fine concave and convex surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubricating conditions, reducing noise and improving the service life of the machine.

2. Sandblasting before workpiece coating and workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece. The abrasives of the exhibition abrasive tools reach different degrees of roughness, which greatly improves the bonding force between the workpiece and the paint and plating. Or make the bonding parts more firm and better in quality.

3. Cleaning and polishing sandblasting of rough surface of castings and workpieces after heat treatment can clean all dirt on the surface of castings and forgings and workpieces after heat treatment, and polish the surface of workpieces to improve the smoothness of workpieces, so that the workpieces can reveal uniform and consistent metal forging color. Make the workpiece appearance more beautiful and good-looking.

4. Lighting effect For some special-purpose workpieces, sandblasting can achieve different reflections or matts at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade articles, the mattization of the surface of wooden furniture, the pattern of frosted glass surfaces, and the textured processing of cloth surfaces.

5. Burr cleaning and surface beautification of machined parts Sandblasting can clean the tiny burrs on the surface of the workpiece, make the surface of the workpiece more flat, eliminate the harm of burrs, and improve the grade of the workpiece. And sandblasting can make small rounded corners at the junction of the workpiece surface, making the workpiece more beautiful and more precise.
