What Types of Parts Can be Machined by CNC Machining

CNC machining in the position of CNC equipment is very high, many parts processing enterprises will be applied to CNC machining center, Qile industry is no exception.

I have analyzed before, why we often choose the CNC machining hand model, we are not clear can go to understand, the application of such a wide range of CNC machining, then do you know what types of parts it can process?

Today we will talk about CNC technology and which parts can be processed!

As we all know, a CNC machining center is suitable for processing complex, working procedures, higher requirements, need to use a variety of types of ordinary machine tools and many tool fixtures, and after several clamping and adjustment to complete the processing of parts.

Types of Parts Can be Machined by CNC Machining?

The main objects of its processing are box parts, complex curved surfaces, special-shaped parts, plate parts and special processing, and other five categories.

01. Box Parts

Box parts generally refer to the parts with more than one hole system, internal cavity, and a certain proportion in the direction of length, width, and height.

These kinds of parts in machine tools, automobiles, aircraft manufacturing, and other industries are used more. Box parts generally need to carry out multi-position hole system and plane processing, the tolerance requirements are higher, especially the shape and position tolerance requirements are more strict.

Processing box-type parts of the processing center, when the processing station is more, the need to rotate the table many times to complete the parts, the general selection of horizontal boring and milling type machining center.

When the processing station is less, and the span is not large, the optional vertical machining center, processing from one end.

02. Complex Curved Surface

The complex curved surface plays an important role in the machinery manufacturing industry, especially in the aerospace industry.

It is difficult or even impossible to complete a complex surface by the ordinary machining method. In our country, the traditional method is to use precision casting, which can be imagined that accuracy is low.

Complex curved parts such as various impellers, wind turbines, spheres, various curved forming molds, propellers, underwater vehicle thrusters, and some other shapes of free-form surfaces.

Typical of the following:

①Cam, CAM Mechanism

As a basic element of mechanical information storage and transmission, it is widely used in various automatic machines. Processing such parts according to the complexity of the CAM selection of three-axis, four-axis linkage, or the selection of a five-axis linkage machining center.

② Integral Impeller Class

These kinds of parts are commonly found in the compressor of aero engine, expansion machine of oxygen making equipment, single screw air compressor, etc., for such a profile, the machining center can be completed by using more than four-axis linkage.

③ The Mold Class

Such as injection mold, rubber mold, vacuum forming blister mold, refrigerator foaming mold, pressure casting mold, precision casting mold, etc.


It can be milled by a machining center. Three-axis milling can only be approximated by a ball-end milling cutter, which is low inefficiency. Five-axis milling can be approximated by a ball-end milling cutter as an envelope surface.

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

03. Profiled

The special-shaped parts are parts with an irregular shape, and most of them need the mixed processing of points, lines, and surfaces.

The rigidity of special-shaped parts is generally poor, the clamping deformation is difficult to control, the processing accuracy is difficult to guarantee, and even some parts of the processing parts with ordinary machine tools are difficult to complete.

When processing with processing center, reasonable technological measures should be adopted, one or two times clamping, using the characteristics of multi-station point, line, and surface mixed processing of processing center, to complete multiple processes or all the process content.

04. Disk, Sleeve, Plate Parts

With keyway, or radial hole, or end face with the distribution of holes, curved disc cover or shaft parts, such as flanged sleeve, with keyway or square head of shaft parts, as well as plate parts with more porous processing, such as all kinds of the motor cover.

A vertical machining center should be selected for disk parts with distributed holes and curved surfaces at the end, and a horizontal machining center with radial holes is optional.

05. Special Processing

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

A High-frequency EDM power supply is installed on the spindle of the machining center, which can carry out line scanning surface quenching on the metal surface.

The grinding of small modulus involute bevel gears and various curves and surfaces can be realized by installing a high-speed grinding head in the machining center.

From the above introduction, it is not difficult to see that the CNC machining center has a wide range of applications, and more types of processing workpiece, so many enterprises in the precision parts, molds, and other processing need to use CNC machining center, of course, the price of this equipment is expensive, in the use of the process must be more maintenance and maintenance.
