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 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 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
Several common surface treatments for steel structure bolts
Electroplating, hot dip galvanizing and mechanical equipment plating on the surface of fasteners are widely used. The whole process of creating a soil layer on the surface of fasteners can show a more beautiful and elegant surface after surface treatment, and the corrosion resistance of fasteners themselves will gradually improve.The key goal is to make the fasteners themselves get corrosion resistance, in order to improve the credibility and adaptability of fasteners application, so the quality of the surface treatment of fasteners to distinguish, the key is to check whether the corrosion resistance of fasteners is reasonable, and the intensity of the improvement is not in line with the estimated provisions.
1, fasteners, fastener of electroplating electroplating is refers to the fasteners must be part of the electroplating entering into a special solution, the solution will have some accumulation of metal materials, chemical substances, as in electricity flow according to the solution, the aqueous solution of metal materials chemical dissolving and adhesion on into part of the fasteners.The electroplating of fasteners generally includes hot dip galvanizing, copper, nickel, chromium, copper nickel alloy, etc.
2, fastener hot dip galvanized fasteners is the fastener of carbon steel components into the attention of about 510 degrees of molten zinc plating tank, so that the surface of the fastener iron zinc alloy material will change to passivation zinc treatment, and then get the actual effect of surface treatment.The price of hot-dip galvanized fasteners is higher than that of electroplating, about 1.5¥ ~2 ¥ for 1 kg.
3, mechanical equipment of fasteners plating mechanical equipment plating fasteners refers to according to the special physical and organic chemistry way, with coating metal material powder, impact the surface of the fastener, so that the coating metal material according to the way of cold welding, produce coating on the surface of the fastener, to achieve the actual effect of surface treatment.Mechanical equipment of fasteners plating key applicable screws, nuts, gaskets and other accessories.
Main products: steel structure bolts and nuts, high strength bolts and nuts, hex bolts, hex nuts, chemical bolts and nuts, and more types of customized screws, nuts and bolts.
