With the growth of the economy, the field of CNC machining customization technology has been expanding rapidly. Numerous CNC machining custom industries are currently in high demand, but many factories that require processing have limited knowledge on the subject. As a result, they may be unaware of the latest advancements in the field, and thereby miss out on the opportunity to improve their operations.
CNC machining customsIn today's market, there are various types of CNC machining customization technologies available, making it difficult for consumers to choose the right one. Hence, this article aims to educate readers on some general knowledge of the CNC machining customization technique.
Customized CNC machining has become more popular with the passage of time. Many manufacturers offer different types of technologies, which can make the decision-making process quite cumbersome for consumers. Therefore, it is essential to gain knowledge of CNC machining customizations.
In conclusion, this article serves as a guide for those seeking information about CNC machining customization technology. It will help you to make a well-informed decision while purchasing your customized product.
Precision machining, also known as precision engineering, involves the process of removing material through precise machining techniques. CNC, or Computer Numerical Control, machining is a popular method used for precision machining. This technique utilizes high-precision machining machines to create accurate and precise parts, often used in industries such as aerospace and medical devices. To achieve the highest level of accuracy, high-precision machine tools are used along with error compensation techniques to improve the machining accuracy of the parts. Overall, precision machining plays a crucial role in the production of high-quality parts for various industries.
There are two main types of machining: manual machining customization and CNC machining customization. Manual machining customization is a method in which the machine operator processes various materials by manually operating machine equipment (such as milling machines, lathes, drill presses, and saws).
Custom CNC machining is a highly precise form of mechanical operation that employs CNC equipment for machining centers, powder processing centers, WEDM equipment, and thread-cutting machines, among others. This type of machining is ideal for large-scale projects and complex parts. On the other hand, manual machining is best-suited for the production of simple parts and small quantities.
The overall amount of metal layer eliminated from the machined surface during the conversion process from raw material to final product is known as the total machining allowance. On the other hand, the thickness of the metal layer deleted during each operation is referred to as the inter-process machining allowance. It is essential to have this allowance calculated so as to determine the degree of machining that is required for the manufacturing process. This will help in ensuring that the finished product is of high quality and standard, meeting the required specifications.
For rotating surfaces (e.g., external circles and holes), the machining allowance is considered in terms of diameter and is therefore called symmetrical abundance (i.e., bi-directional abundance). In other words, the actual thickness of the removed metal layer is half the diameter of the machining allowance. The machining allowance for a flat surface is a single edge allowance, such as the thickness of the metal layer being removed.
Machining allowance is deliberately left on the blank to ensure that any potential errors and surface defects from the previous process are eliminated. These may include a cold hard layer, porosity, vermilion layer, oxide on the forging surface, decarburization layer, surface cracks, internal stress layer after cutting, and surface roughness. By leaving machining allowance on the blank, a high working accuracy can be achieved, and surface roughness can be minimized.
The size of the machining allowance has a great impact on machining quality and productivity. Too much machining allowance will not only increase machining workload and reduce productivity but also increase material, tool, and power consumption, thus increasing machining cost.
Too small a machining allowance cannot eliminate various defects and errors in the previous process, nor can it compensate for fixture errors during the machining of that process, thus producing scrap. The principle of selection is to ensure quality and to make the margin as small as possible. Generally speaking, the more you finish, the smaller the margin.
