①Reducing the number of toolings in large quantities, and machining complex-shaped parts does not require complicated tooling. If you want to change the shape and size of parts, you only need to modify the parts processing program, which is suitable for the development and modification of new products.
②The processing quality is stable, the processing precision is high, and the repeat precision is high, which can meet the processing requirements of the aircraft.
③The high production efficiency in the case of multi-species and small-batch production can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the optimum cutting amount.
④Machinable complex surfaces that are difficult to process with conventional methods can be machined, and even machined parts that are not observable can be machined.
The disadvantage of CNC machining is that machine tool equipment is expensive and requires maintenance personnel to have a high level.
The traditional processing technology adopts low-speed, high-power spindles, low feed speed, large cutting capacity, and the parts are subjected to large cutting forces. Large heat will be generated on the surface of the workpiece, and the workpiece will be greatly deformed due to thermal deformation. Shortened, traditional processing methods such as longer processing time, processing accuracy, relatively poor finish, loss. The high-speed machining process uses a small cutting amount and a feed speed, 5-10 times the cutting speed of the traditional machining method, which means that the spindle bearings and parts are subjected to a small cutting force. Due to the high cutting speed, most of the heat generated during processing is When it is cut away by iron, the workpiece can have a very good surface finish and machining accuracy, while significantly reducing the processing time.
