Part machining process route refers to the production process of parts, from the blank to the finished product through the sequence of processes. In the development of the process route, in addition to the first consideration of the choice of positioning datum, should also consider the choice of surface processing methods, the degree of concentration and dispersion of the process, the division of the processing stage and the arrangement of the sequence of processes and other issues. At present, there is not a set of general and complete process route formulation method, only some comprehensive principles are summarized, in the

Most of the power tools on CNC lathes have only a limited speed of 5000r/min, for large diameter tools this speed limit will not be a problem, however, most of the machining on Swiss machines is small diameter, for small diameter drills and milling tools, high speed is extremely critical to increase the feed rate and to provide productive cutting efficiency accordingly. High-speed electric spindles always significantly reduce the cycle time for drilling, which is usually the slowest process, to 1/5 of the original drilling time. IBAG, a Swiss manufacturer of precision high-speed electrospindles, has brought micro-precision high-speed milling and

De-coring and surface cleaning: Divided into two types, dry and wet. Dry cleaning is the use of mechanical equipment to clean the castings. The equipment used is simple, the production efficiency is high, it has the advantages of greater adaptability to different types of castings and can remove the core and effectively clean the surface. The disadvantage is that the equipment is often dusty, noisy, and pollute the environment during operation. Wet cleaning has no dust, but because water is used as a medium, the surface of the investment casting is easy to rust. During the operation, a large amount

Aluminum casting is a kind of parts made by pressure casting. It uses pressure casting machinery with investment casting molds to cast aluminum or aluminum alloy heated to liquid into the inlet of the aluminum casting. Die casting parts and then cast the castings you want. Aluminum castings are widely used in motorcycle manufacturing, electric motor manufacturing, automobile manufacturing, internal combustion engine production, oil pump manufacturing, landscaping, transmission machinery manufacturing, precision instruments, power construction, architectural decoration and other industries. In the manufacturing process of aluminum castings, the formulation and execution of the die-casting process are closely related to the quality

Whether the structure of the aluminum casting is reasonable will have a great impact on the quality of the casting and the feasibility and simplicity of the production process. The structure of the aluminum casting is equivalent to the production characteristics of investment casting, so part of the investment casting is reasonable Examples of structures. In order to effectively ensure the quality of investment castings in the production process of aluminum castings, it is often necessary to effectively set process ribs and holes on the investment castings according to needs, so the reference size of the process rib design is

Brass casting is a kind of brass molding object Bai obtained by various casting methods, that is, the melted liquid metal is injected into the prepared casting mold by pouring, injection, inhalation or other casting methods, and then cooled, sand falling, cleaning and post-treatment are carried out to obtain the object with certain shape, size and performance. Brass casting has a long history of application. In ancient times, people used castings to make coins, sacrificial vessels, weapons, tools and some living utensils. In modern times, brass casting is mainly used as blank of machine parts, and some precision castings can

Method to solve casting porosity First analyze the reasons for the formation of stomata, and then take corresponding measures. Choose the right die casting machine Die-casting machine is the key equipment for die-casting production, and its performance objectively determines the quality of die-casting parts. The correct choice of die-casting machine is essential to ensure product quality, improve production efficiency and reduce production costs. The performance of the die casting machine depends on two aspects. Sufficient clamping force: to prevent the flow pressure of the molten metal from reaching high peaks, and to prevent flashing and flying materials. Sufficient injection capacity:

For zinc alloy die castings to be electroplated surface treatment, this link is very important. If the electroplating is not done well, all the work in the early stage will be wasted. Therefore, we must pay attention to the electroplating process of the product. Then the quality of electroplating is affected by those factors. Carbide die casting summarizes the following for you: Zinc alloy die casting The main factors affecting the electroplating quality of zinc alloy die castings are summarized in the above seven points. We focus on the customization of the die casting industry and have our own surface
