As we all know, CNC Machining centers are suitable for processing parts that are complex, have many processes, have high requirements, require various types of ordinary machine tools and many tool holders, and can only be processed after multiple clamping and adjustments. The main objects processed by its CNC Machined Parts include box-type parts, complex curved surfaces, special-shaped parts, plate-type parts and special processing.
1. Box parts Generally, it refers to a part with more than one hole system, a cavity inside, and a certain proportion in the length, width, and height directions. Such parts are widely used in machine tools, automobiles, aircraft manufacturing and other industries. Box-type parts generally require multi-station hole system and surface processing, which require high tolerances, especially strict requirements for shape and position tolerances. For machining centers that process box-type parts, when there are many processing stations and the parts need to be rotated multiple times to complete the parts, horizontal boring and milling machining centers are generally selected. When there are fewer processing stations and the span is not large, a vertical machining center can be selected to process from one end. 2. Complex surface Complex curved surfaces occupy a particularly important position in the mechanical manufacturing industry, especially in the aerospace industry. It is difficult or even impossible to complete complex curved surfaces with ordinary machining methods. In our country, the traditional method is to use precision casting, and it is conceivable that its precision is low. Complex curved surface parts such as: various impellers, wind deflectors, spherical surfaces, various curved surface forming molds, propellers and propellers of underwater vehicles, and some other shapes of free-form surfaces. Our processing products include CNC Turning, CNC Milling, Electrical Discharge Machining, Hard Turning, Wire EDM Components, 5 Axis Cnc Milling, if you want to know more, please contact us.
The more typical ones are as follows: ①Cam, cam mechanism As the basic element of mechanical information storage and transmission, it is widely used in various automatic machines. To process such parts, three-axis, four-axis linkage or five-axis linkage machining centers can be selected according to the complexity of the cam. ②Integral impeller Such parts are commonly found in compressors of aero-engines, expanders of oxygen-generating equipment, single-screw air compressors, etc. For such profiles, machining centers with more than four axes linkage can be used to complete them. ③Mould Such as injection molds, rubber molds, vacuum forming plastic molds, refrigerator foam molds, pressure casting molds, precision casting molds, etc. ④Spherical surface Machining centers can be used for milling. Three-axis milling can only use a ball end mill for approximation processing, which is less efficient. Five-axis milling can use an end mill as an envelope surface to approach a spherical surface. When complex curved surfaces are processed by machining centers, the programming workload is relatively large, and most of them require automatic programming technology.
