What Parts Are Usually Used In Cnc Machining?
As we all know, CNC Machining machining centers are suitable for complex machining, multi-process, high-demand and high-demand, various types of ordinary machine tools and various fixtures, parts that require multiple clamping and adjustments. Its processing objects are mainly box parts, complex curved surfaces, special-shaped parts, composite board parts and CNC processing.
(1) box parts
Box parts, such as Mini computer enclosure, generally refer to parts with a porous system, an inner cavity, and a certain ratio of length, width, and height. Such parts are mainly used in industries such as machine tools, automobiles, and aircraft manufacturing. Box parts generally require multi-station hole making and surface processing, and require high tolerances, especially relatively strict requirements for shape and position tolerances. They are usually milled, drilled, expanded, bored, reamed, spot welded, tapped, and other processes that require more tools. The machining center is used to process box parts. When there are multiple processing stations and the parts can only pass through the work, the boring and milling machining center is generally selected.
(2) complex surface
Complex surfaces play a very important role in mechanical manufacturing, especially in the aerospace industry. Complicated surfaces are difficult or even impossible to achieve using common machining methods. In our country, the traditional casting method is precision casting, and its precision is conceivably low. Complex surface parts.
(3) Special-shaped parts
Special-shaped parts are irregular parts, most of which require mixed processing of points, lines and surfaces. The rigidity of special-shaped parts is generally poor, and the clamping deformation of different Bending Parts is difficult to control, and the machining 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 to clamp once or twice. The mixed processing characteristics of the machining center have multi-stations and can complete multiple or all processes.
(4) Discs, sleeves and plates
For disc-shaped parts with keyways or radial holes or distributed hole systems, curved disc sleeves or shaft zeros, such as flanged sleeves, keyway or square head shaft parts, and porous processing plates, vertical machining centers should be selected, such as For disc parts with distributed holes and curved surfaces on the end faces of various motors, a horizontal machining center with radial holes should be selected.
(5) Test pieces for new products
The machining center has wide adaptability and high flexibility. When changing the processing object, CNC processing can be realized by compiling and inputting a new program.
