Process concentration, automation, high flexibility, the strong ability is
the characteristics of NC machining. Numerical control machine tool processing
and the traditional machine tool processing process are generally consistent,
but there are obvious changes. So what are the characteristics of CNC
One, process concentration: CNC machine tools generally with automatic tool
change tool holder, tool library, tool change process is controlled by the
program automatically, therefore, the process is more concentrated. Process
concentration brings huge economic benefits:
1. Reduce the area of machine tools and save the workshop.
2, reduce or no intermediate links (such as intermediate testing of
semi-finished products, temporary storage, handling, etc.), both save time and
Two, automation: CNC machine tool processing, without manual control of the
tool, high degree of automation. The benefits are obvious.
1, to reduce the requirements of the operator: an ordinary machine tool of
senior workers, not in a short time can be cultivated, and a CNC worker without
programming training time is very short (such as CNC lathe workers need a week,
will also write simple processing procedures). And, numerical control workers in
numerical control machine tool processing parts than ordinary workers in the
traditional machine tool processing parts of high accuracy, time to save.
2, reduce the labor intensity of workers: CNC workers in the processing
process, most of the time is excluded in the processing process, very
3, stable product quality: CNC machine tool processing automation, eliminate
the fatigue of ordinary machine tool workers, is careless, estimate and other
human error, improve the consistency of the product.
4, high processing efficiency: CNC machine tool automatic tool change so that
the processing process is compact, improve labor productivity.
Three, high flexibility: the traditional general machine tool, although good
flexibility, but low efficiency; While the traditional special aircraft,
although high efficiency, but poor adaptability to parts, large rigidity, poor
flexibility, it is difficult to adapt to the fierce competition under the market
economy brought frequent product modifications. As long as the program changes,
you can process new parts on CNC machine tools and can be automated operation,
good flexibility, high efficiency, so CNC machine tools can well adapt to market
Four, strong ability: machine tools can accurately process all kinds of
contours, and some contours can not be processed on ordinary machine tools. CNC
machine tools are especially suitable for the following occasions:
1, do not scrap parts.
2. Development of new products.
3. Processing of urgent parts.
Numerical control processing than the traditional machine tool processing has
changed a lot, the efficiency is also greatly improved, which is the benefit
brought by the continuous development of science and technology.
