CNC machining is CNC machine tool processing, that is, a set of processing program is compiled by computer, and the article is processed by digital milling machine. The same is true for CNC processing of aluminum profiles. Including cutting, drilling, tapping and so on, basically depends on CNC operation. CNC processing can reduce the damage rate of products, which is favored by aluminum profile manufacturers.
Advantages: ① greatly reduce the number of tooling, complex processing forms of parts do not need complex tooling. If we want to change the form and size of parts, we only need to modify the part processing program, which is applicable to the development and modification of new products.
② The machining quality is stable, the machining precision is high, and the repeated precision is high, which is suitable for the processing requirements of aircraft.
③ It can reduce the time of production planning, machine tool adjustment and process inspection, and reduce the cutting time due to the use of good cutting amount.
④ It can be used to machine the complex surface which is difficult to machine by conventional way, and even can process some parts which cannot be observed.
The disadvantage is that the processing equipment is relatively high, and the quality requirements of operators are high.
