What are the CNC spare parts processing?

2023-07-19

As we all know, CNC Machining center is suitable for processing parts that are complex, have many processes, have high requirements, require a variety of types of ordinary machine tools and a variety of tool fixtures, and need to be clamped and adjusted multiple times. Its processing objects are mainly box parts, complex surfaces, special-shaped parts, package parts and special processing. What are the CNC spare parts processing?

1. Box spare parts:

Box parts generally refer to parts with multiple hole systems, internal cavities, and a certain proportion of length, width and height. Such parts are mostly used in machine tools, automobiles, aircraft manufacturing and other industries. Box-shaped parts generally require multi-station hole system and plane machining, and the tolerance requirements are high, especially the shape and position tolerance requirements are relatively strict, usually through milling, drilling, expansion, boring, reaming, countersinking, tapping and other processes, requiring more tools. For machining centers that process box parts, when there are many machining stations and parts that need to be rotated several times to complete, horizontal boring and milling machining centers are generally selected.

2. Complex surface parts:

Complex curved surfaces play a particularly important role in mechanical engineering, especially in the aerospace industry. Complex surfaces are difficult or even impossible to complete using common machining methods. In China, the traditional method is to use precision casting, which can be imagined to have low precision. Complex curved parts such as various impellers, wind deflectors, spherical surfaces, various curved forming molds, propellers and underwater vehicle propellers, and other freeform surfaces.

Third, special-shaped parts and accessories

Special-shaped parts are irregularly shaped parts, most of which require multi-station mixed processing of points, lines and surfaces. The rigidity of special-shaped parts is generally poor, clamping deformation is difficult to control, processing 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 technological measures should be taken, one or two clamping, and the characteristics of multi-site, line and surface mixed processing of the machining center should be used to complete multiple processes or all processes.

4. Discs, sleeves and plate parts:

End faces with keyways, or radial holes, or distributed hole systems, curved disc sleeves or shaft parts, such as flange bushings, keyways or square shaft parts, etc., as well as multi-hole machining plates, such as various motor end faces with distributed holes and curved disc parts should be selected vertical machining center, and horizontal machining center with radial hole should be selected.

5. New product trial production spare parts:

CNC machining centers have wide adaptability and high flexibility. When changing the machining object, it is only necessary to compile and enter a new program to realize machining.
