Which kind of parts can be CNC machined?

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.


01、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-type parts generally require multi-station hole system and plane processing, with higher tolerance requirements, especially the stricter form and position tolerance requirements.

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.

02、Complex 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:

①Cam, cam mechanism

As the basic element of mechanical information storage and transmission, it is widely used in various automatic machinery. For processing such parts, three-axis, four-axis linkage or five-axis linkage machining center 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 production equipment, single-screw air compressors, etc. For such a profile, a machining center with more than four-axis linkage can be used to complete.

③Moulds

Such as injection molds, rubber molds, vacuum forming blister molds, refrigerator foam molds, pressure casting molds, precision casting molds, etc.

④Spherical surface

It can be milled by a machining center. Three-axis milling can only use ball-end milling cutters for approximation processing, which is less efficient. Five-axis milling can use end milling cutters as the envelope surface to approach the spherical surface.

When the complex curved surface is processed by the machining center, the programming workload is relatively large, and most of them require automatic programming technology.

03、 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 machining 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.

04、 Discs, sleeves, 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.

05、 Special processing

After mastering the functions of the machining center, with certain tooling and special tools, the machining center can be used to complete some special process tasks, such as engraving, engraving, and patterns on the metal surface.


A high-frequency electric spark power supply is installed on the main shaft of the machining center to perform line scan surface quenching on the metal surface.

The machining center is equipped with a high-speed grinding head, which can realize the grinding of small modulus involute bevel gears and the grinding of various curves and curved surfaces.

From the above introduction, it is not difficult to see that CNC machining centers have a wide range of applications and there are many types of workpieces to be processed. Therefore, many companies need to use CNC machining centers in the processing of precision parts, molds, etc., of course. The equipment is expensive and must be maintained and maintained during use.
