Electroplating is often mentioned in the production process of hand board. It is a commonly used surface treatment technology in hand board production. Then, what is the role of electroplating technology in hand board manufacturing? Electroplating is the process of plating a thin layer of other metals or alloys on the metal surface using the principle of electrolysis. The purpose of electroplating is to coat the metal coating on the substrate and change the surface properties or dimensions of the substrate Electroplating can enhance the corrosion resistance of metal (the coating metal mostly adopts corrosion-resistant metal), increase hardness, prevent abrasion,…

Full CNC process? die-casting? CNC + die casting? Before restoring the manufacturing journey of mobile phone shell, let's clarify several concepts: full CNC process and die-casting process, and CNC + die-casting. The middle frame of full CNC mobile phone is milled into a specific shape through the CNC machining center. Die-casting is to use the mold cavity to apply high pressure to the molten metal and die-casting the fluid metal into a solid metal shell or middle frame, Of course, there is the practice of combining the two processes. Think about it with the appendix. The cost of full CNC…

A car is composed of more than 10000 parts and components. Each part must be processed and formed through different processes before it can be assembled on the car. Today, let's take a look at the processing technology of seven auto parts. 1. About casting Casting is a production method in which molten metal is poured into the mold cavity, cooled and solidified to obtain products. In the manufacturing process of various parts, such as the cylinder body and the brake drum, many parts are made of cast iron, accounting for about 10% of the total weight of the vehicle…

CNC hand board processing is usually divided into four links: 1. Rough machining. Rough machining is mainly to cut off most of the machining allowance on each surface to make the shape and size of the blank close to the finished product. This stage is characterized by the use of high-power machine tools and large cutting tools to improve productivity and reduce tool wear as much as possible. 2. Semi finishing. Semi finishing is to finish the machining of the secondary surface and prepare for the finishing of the main surface. 3. Finish machining. Finish machining is to ensure that…

Integral impeller is the core component of turbo engine and turbocharged engine. It is widely used in energy and power, aerospace, petrochemical industry, metallurgy and other industries. It is a representative, standardized and typical channel complex part. The machining means, machining accuracy and machining surface quality of its profile directly affect the aerodynamic performance and mechanical efficiency of the engine, and have a decisive impact on the performance of the engine. Integral impeller has become a typical difficult to machine part because of its complex surface and high machining precision. With the increasing market demand for turbine engine, it is…

Abstract: five axis linkage milling can optimize the cutting process and parameters, which is conducive to reducing tool wear and post machining. It is the trend of the development of automobile mold processing technology. It is suitable for machining convex surface and shallow concave surface with small curvature with ball end milling cutter. It can also be used for machining free surface with side of milling cutter. The 3 + 2 axis machining method can speed up the tool walking to the greatest extent. NC milling has higher precision and less post-processing than profiling milling. The realization of five axis…

With the rise of the automobile industry, there are more and more five axis CNC machine tools. However, in the current market, there are few real five axis (RTCP function) machine tools and many fake five axis (only indexing function) machine tools. What is true five axis, what is false five axis, and what is the difference between three axis? The following description is as follows. True five axis has RTCP function. It can automatically convert according to the swing length of the main shaft and the mechanical coordinates of the rotating table. When compiling the program, only the coordinates…

The modeling design of mechanical products belongs to the category of "industrial design". Industrial design is a new frontier discipline in modern times. It is a creative design that applies engineering technology and artistic means to design and shape the image of products, and finally unifies it in the function, structure, process, agreeableness, visual communication and market relationship of products, so as to achieve the harmony between man, machine (product) and environment. With the advance of the times, the development of science and technology, the improvement and change of people's aesthetic concept, the modeling design of mechanical products, like other…

EDM is an important process method of mold manufacturing, especially in plastic mold manufacturing. The cavity of plastic mold, many groove corners of sliding block, insert, inclined pin and other parts need EDM. Because EDM is a process method with slow processing speed, EDM needs to spend more man hours in mold manufacturing. How to improve the machining speed of EDM machine tools on the premise of ensuring the machining quality through effective and feasible process measures, and how to shorten the mold manufacturing cycle and reduce the mold manufacturing cost by relying on high-efficiency EDM production has always been…

Thermit welding: during welding, the ends of the two workpieces to be welded are fixed in the mold in advance, and then the mixture of aluminum powder and iron oxide powder (called thermite) is heated in the crucible to make it undergo reduction exothermic reaction to become liquid metal (iron) and slag (mainly Al2O3) and injected into the mold. The liquid metal flows into the gap of the joint to form the weld metal, and the slag floats on the surface. Sand mold casting: a casting method for generating castings in sand mold. Basic raw materials: casting sand and molding…
