Which parts can be processed by CNC machining center?
CNC machining center is applicable to complex processing, multiple processes, high requirements and multiple requirements
Type of common machine tools and various tool clamps, which can only be added after multiple clamping and adjustment
A part of a machine. The machining objects are mainly box parts, complex curved surfaces and special-shaped Parts, cladding parts and special processing.
CNC machining occupies a very high position in CNC equipment. Many parts processing enterprises
CNC machining center will be applied. What types of zeros can CNC machine
What about pieces? It is believed that many practitioners know that CNC machining centers are suitable for complex
There are many processes, high requirements, and various types of ordinary machine tools and tool holders are required
And the parts can only be processed after multiple clamping and adjustment. The processing objects are mainly
Box parts, complex curved surfaces, special-shaped parts, clad plate parts and special processing.
(1) Box parts.
Box parts generally refer to those with multiple hole systems, cavities inside, long, wide and high
Parts with a certain proportion. Such parts are mostly used in machine tools, automobiles, aircraft manufacturing, etc
Industry. Box shaped parts generally need multi station hole system and plane processing, and the tolerance requirements are relatively
High, especially the form and position tolerance requirements are relatively strict, usually through milling, drilling, expanding
Boring, reaming, spot facing, tapping and other processes require more tools. For machining box
For the machining center of parts, when there are many machining stations, the workbench needs to rotate for many times
For finished parts, horizontal boring and milling machining center is generally selected.
(2) Complex surfaces.
Complex surfaces play an important role in the mechanical manufacturing industry, especially in the aerospace industry
Status. It is difficult or even impossible to complete complex curves with ordinary processing methods
noodles. In China, the traditional method is to use precision casting, which can be imagined to be more accurate than
Low. Complex curved surface parts, such as various impellers, air guide wheels, spherical surfaces, and various curved surfaces
Forming mould, propeller and underwater vehicle propeller, and other free curves noodles.
(3) Special parts.
Special shaped parts are irregular in shape, and most of them require multiple stations of points, lines and surfaces
Mixed processing. The rigidity of special-shaped parts is generally poor, and the clamping deformation is difficult to control
It is difficult to ensure the accuracy, and even some parts of some parts are difficult to complete with ordinary machine tools
Cheng. When machining with a machining center, reasonable process measures should be taken, one or two times
Clamping, using the characteristics of multi station point, line and surface mixed processing of the machining center
Multiple processes or all processes.
(4) Disc, sleeve and plate.
End face with keyway, or radial hole, or distributed hole system, curved disc sleeve or shaft parts,
Such as flange shaft sleeve, keyway or square head shaft parts, as well as porous processing plates, such as
The disc parts with distributed holes and curved surfaces on the end faces of various motors shall be processed vertically
The horizontal machining center with radial holes shall be selected.
(5) Trial production parts of new products
The machining center has wide adaptability and high flexibility. When changing the processing object, just compile and input
Processing can be realized by entering a new program.
