CNC lathe is one of the most widely used CNC machine tools. It is mainly used for machining symmetrical rotary parts, such as shaft parts, inner and outer cylindrical surfaces of disk parts, inner and outer conical surfaces with arbitrary cone angles, complex inner and outer curved surfaces of rotation, and cylindrical and conical threads.
Austenitic 304 stainless steel is a very common stainless steel with corrosion resistance, heat resistance, low temperature strength and overall mechanical properties. Widely used in food equipment, chemical equipment and nuclear industry equipment.
In the process of thread CNC turning, it is often necessary to reinstall the tool and set the tool due to the wear and tear of the thread tool. The quality of the tool setting directly affects the accuracy of the turning thread, especially the repair turning of the thread, which requires secondary clamping The second tool setting restricts the machining efficiency of CNC lathe machining threads.
Aluminum alloy die casting refers to the method in which liquid aluminum alloy flows from the pressure chamber into the mold cavity at an extremely fast speed under high temperature and high pressure, and forms a casting after cooling.
Etching usually refers to photochemical etching, which refers to removing the protective film of the area to be etched after exposure and development of the plate, making the metal contact with the chemical solution during etching, and using two positive patterns to achieve the effect of dissolution and corrosion through chemical grinding from both sides. To form the effect of concave-convex or hollow molding, chemical etching is very targeted. It refers to controlled corrosion. It is a controllable processing method for metals through chemical methods.
The surface treatment of aluminum alloy is usually anodized, which is not suitable for electroplating.The common surface treatment of zinc alloy die casting is electroplating, which is not suitable for anodizing.Aluminum alloy die castings are also not suitable for anodizing effect is relatively poor, those with high appearance requirements should be used with caution.
Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to molten metal, similar to plastic injection molding. Die casting is especially suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used of various casting processes. Compared with other casting technologies, die casting has a flatter surface and higher dimensional consistency. However, irregular operations and parameters can also produce a wide variety of defects.
Common electroplating is divided into specific processes such as copper plating, gold plating, silver plating, chrome plating, nickel plating, and galvanizing. Among them, galvanization, nickel plating, and chrome plating are the most widely used in the manufacturing field, so what is the difference between the three?
