Let's familiarize ourselves with the processing technology of our CNC

CNC machining in the status of CNC equipment is very high, many parts processing enterprises will be applied to CNC machining center, SOMIR is no exception. I have analyzed before, why we often choose CNC processing hand model, we are not clear can go to understand, so widely used CNC processing, then do you know what types of parts it can be processed?

Today we are going to talk about CNC technology which parts can be processed!

As we all know, 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 many clamping and adjustment to complete the processing of parts.

The main objects of its processing are box parts, complex curved surface, special-shaped parts, plate set 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, in the direction of length, width and height have a certain proportion

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

Machining box parts of the machining center, when the processing station is more, the need for multiple rotation of the table to complete the parts, generally choose horizontal boring and milling 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 Surface Complex surface is difficult or even impossible to complete by ordinary machine processing method. In China, the traditional method is to use precision casting, which can be imagined to be low.

Complex surface parts such as: various impellers, wind guides, spheres, various surface forming dies, propellers and propeller of underwater vehicles, as well as some other shapes of free surface.

Typical of the following:

CAM and CAM mechanism, as the basic components of mechanical information storage and transmission, are widely used in various automatic machinery. This kind of parts can be processed according to the complexity of the CAM selection of three axis, four axis linkage or five axis linkage machining center. â‘¡ Integral impeller such parts are common in aero-engine compressor, oxygen equipment expander, single screw air compressor, etc., for such a profile, can use more than four axis linkage machining center to complete. â‘¢ Moulds such as injection moulds, rubber moulds, vacuum forming blister moulds, refrigerator foam moulds, pressure casting moulds, precision casting moulds, etc. â‘£ The spherical surface can be milling with machining center. Three-axis milling can only be approximated by ball-end milling cutter, which has low efficiency. Five-axis milling can be approximated by end-milling cutter as envelope surface. When machining complex surface with machining center, the programming workload is large, most of them need automatic programming technology.

03 profiled

Special-shaped parts are irregular shape parts, most need point, line, surface multi-station mixed processing.

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

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

04 Plate, sleeve and plate parts

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

Complex surface plays a very important role in machinery manufacturing, especially in aerospace industry. Vertical machining center should be selected for disk parts with distributed holes and curved surfaces, and horizontal machining center with radial holes is optional.

05 special processing after mastering the function of the processing center, with certain tooling and special tools, the use of processing center can complete some special process work, such as engraving on the metal surface, engraving line, engraving pattern. A high frequency edM power supply is installed on the main shaft of the machining center, and the metal surface can be hardened by line scanning. The grinding of small modulus involute bevel gears and various curves and surfaces can be realized by installing high speed grinding head on the machining center. From the above introduction, it is not difficult to see that CNC machining center has a wide range of applications, and more types of workpiece processing, so many enterprises need to use CNC machining center for precision parts, molds and other processing, of course, the price of this equipment is expensive, in the process of use must be more maintenance and maintenance.
