Did Changchun FAW CNC work well?

It is not easy and tiring to do numerical control, and the numerical control work of Changchun FAW is not good either. In most factories, the numerical control work is two shifts, and the night shift is hard and the working hours are long. To learn CNC, you must first learn to look at standard drawings. For example, wire cutting is an outline, so we don't need to imagine space. We can look at the drawings directly. On the CNC milling machine, we need to turn the planar two-dimensional drawings into three-dimensional objects in our minds, and process them one by one according to the size until the qualified products are made according to the standard tolerance.
