What parts are commonly used in CNC machining?

As is well known, CNC machining centers are suitable for complex machining, multiple processes, high requirements and demands, various types of ordinary machine tools and various fixtures, and parts that require multiple clamping and adjustment. Its processing objects mainly include box parts, complex surfaces, irregular parts, composite plate parts, and CNC machining.

(1) Box parts

Box type parts generally refer to parts with a porous system, inner cavity, and a certain length, width, and height ratio. This type of component is mainly used in industries such as machine tools, automobiles, and aircraft manufacturing. Box type parts generally require multi station drilling and flat machining, with high tolerance requirements, especially relatively strict geometric tolerances. They usually go through milling, drilling, expanding, boring, reaming, spot welding, tapping, and other processes, requiring more tools. A machining center is used to process box parts. When there are multiple machining stations and the parts can only pass through work, a boring and milling machining center is generally chosen.

(2) Complex surfaces

Complex surfaces play a very important role in mechanical manufacturing, especially in the aerospace industry. It is difficult or even impossible to complete complex surfaces using ordinary processing methods. In China, the traditional casting method is precision casting, which can be imagined to have lower accuracy. Complex surface parts.

(3) Irregular parts

Irregular parts are irregular parts that require mixed processing of points, lines, and surfaces at multiple workstations. The stiffness of irregular parts is generally poor, clamping deformation is difficult to control, machining accuracy is difficult to ensure, and even some parts of some parts are difficult to complete with ordinary machine tools. When using a machining center for processing, reasonable process measures should be taken, such as clamping once or twice. The mixed processing characteristics of the machining center have multiple workstations and can complete multiple or all processes
