CNC machining refers to machining with CNC tools. The CNC index control machine tool uses the CNC machining language to tell the CNC machine tool position coordinates and control the feed rate and spindle speed of the tool, as well as the function of the tool changer and coolant.

Compared to manual machining, parts produced by CNC machining are very precise and repeatable. CNC machining can produce parts with complex shapes that cannot be done by hand, and it ensures consistent product quality, greatly increasing production speed and increasing efficiency. Soon CNC machining technology was widely promoted.

The products of Jiamengzi include gang-type CNC lathes, turret CNC lathes, turning and milling CNC lathes, hub-disc CNC lathes, and V series machining centers, which greatly meet various production needs.
