2022 12 29 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.

VMT 2022 12 27 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.

VMT 2022 12 23 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.

VMT 2022 12 21 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.
