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

Hardware Processing Factory: Process Skills for Surface Processing of Hardware Parts

 Surface processing of hardware parts:

  • 1. Spray paint processing: The hardware processing factory uses spray paint processing when producing large hardware products. By using spray paint processing, the hardware can avoid rust, such as: daily necessities, electrical equipment shells, handicrafts, etc.
  • 2. Electroplating: Electroplating is also the most common processing technology for hardware processing. Through the development of modern design process information technology, the surface of the hardware is electroplated to ensure that the product can be used for a long time without mold and embroidery. Electroplating is common There are: screws, stamping parts, batteries, car parts, small accessories, etc.
  • 3. Surface polishing processing: Surface polishing processing is generally used in daily necessities. Through the surface burr processing of hardware products, for example, we produce a comb, and the comb is a hardware part made by analysis and stamping, then stamped out The corners of the comb are very sharp. We need to polish the sharp corners into a smooth face so that it will not cause serious harm to human health during use.
  • 4. Round surface is the basic method of metal processing, and the equipment used is a lathe. In general machinery factories, lathes account for about 40 of the total number of machine tools. Turning is the main method of rough machining and semi-finishing of various materials, and it is also the final finishing method of various materials that are not suitable for grinding.
  • 5. In the production of small batch products, turning the outer surface can generally be done on a normal lathe. In mass industrial production, hardware processing has extensively studied the use of multi-tool semi-automatic lathes or automatic selection lathes. The design of large disc parts should be analyzed and processed on a vertical lathe. Large long shaft parts need to be processed on a heavy-duty horizontal lathe.
  • 6. The characteristics of turning the outer surface are: simple tool, easy to manufacture, sharpen and install;. The cutting process is stable and the cutting force fluctuation is small, which is conducive to adopting high cutting speed and improving productivity. The machine has good versatility and can be clamped out when processing circles, ends, holes, threads and chamfers. The positioning accuracy between the surfaces is easy to ensure, and it is suitable for non-ferrous metal parts.
