CNC Machining Is Often Used In Which Parts Processing

CNC machining has a very high position in CNC equipment. Many parts processing companies will apply CNC machining centers. So what types of parts can CNC machining process? As we all know, CNC machining centers are suitable for machining parts that are complex, have many procedures, are more demanding, require multiple types of ordinary machine tools and many tool fixtures, and can only be processed after multiple clamping and adjustments. The main objects of its processing are box parts, complex curved surfaces, special-shaped parts, plate-covered parts and special processing.

(1) Box Parts.

Box parts generally refer to parts that have more than one hole system, a cavity inside, and a certain proportion of length, width, and height. This kind of parts are used more in machine tool, automobile, aircraft manufacturing and other industries. Box parts generally require multi-station hole system and plane processing, with higher tolerance requirements, especially the stricter form and position tolerance requirements, usually through milling, drilling, expanding, boring, reaming, countersinking, tapping and other processes , Need more tools. For the machining center for processing box parts, when there are many processing stations and the parts that require multiple rotations of the worktable to complete, the horizontal boring and milling machining center is generally selected. When there are few processing stations and the span is not large, you can choose a vertical machining center to process from one end.

(2) Complex Curved Surface.

Complex curved surfaces occupies a particularly important position in the machinery manufacturing industry, especially the aerospace industry. It is difficult or even impossible to complete complex curved surfaces using ordinary machining methods. In our country, the traditional method is to use precision casting, it is conceivable that its accuracy is low. Complicated surface parts such as: various impellers, wind guide wheels, spherical surfaces, various curved surface forming molds, propellers and underwater vehicle propellers, and some other free-form surfaces. The following are more typical:

(3) Special-Shaped Parts.

Special-shaped parts are parts with irregular shapes, and most of them require multi-station mixed processing of points, lines and surfaces. The rigidity of special-shaped parts is generally poor, the clamping deformation is difficult to control, and the machining accuracy is difficult to guarantee, and even some parts of some parts are difficult to complete with ordinary machine tools. When processing with a machining center, reasonable process measures should be adopted, one or two clamping, and the characteristics of the machining center’s multi-station point, line, and surface mixed processing should be used to complete multiple procedures or all procedures.

(4) Discs, Sleeves And Plate Parts.

With keyway, or radial hole, or distributed hole system on the end face, curved disk sleeve or shaft parts, such as flanged shaft sleeve, keyway or square head shaft parts, etc., and more porous Processed board parts, such as various motor covers, etc. Disc parts with distributed holes and curved surfaces on the end surface should choose a vertical machining center, and a horizontal machining center with radial holes should be selected.

(5) Parts In Trial Production Of New Products

The machining center has a wide range of adaptability and high flexibility. When changing the processing object, only need to compile and enter a new program to realize the processing.
