The working principle of CNC lathe is as follows: The computer in the numerical control device carries out a series of processing on the information recorded by the input device in the form of Numbers and character codes,then send instructions to the machine tool spindle, feed and other actuators through the servo system and programmable controller.

The machine body follows these instructions,the workpiece is machined with various required actions under the cooperation of the detection feedback device. For example, the motion track of the cutter relative to the workpiece,displacement and feed speed and other requirements to complete automatic control, so as to complete the workpiece processing.

After the adjustment, enter the program and start,the machine can have automatic continuous processing until the end of the processing.All the operator has to do is input the program, modify it, load and unload the parts, prepare the tools, observe the machining status, inspect the parts and so on.The labor intensity is greatly reduced, the machine tool operator's labor tends to the intellectual work, in addition, the machine tool is generally combined, both clean and safe.

The operating principle of fine parts machining? The control system of CNC fine parts processing can generally operate the machine according to the numerical order. It can automatically start and stop the spindle, change direction and variable speed, and automatically control the feed speed, direction and processing route for machining. It also can able to adjust the amount of feed for cutting tool and running track according to the select tools and the size of the cutting tool, and can complete all kinds of auxiliary actions required in machining.  

Structural CNC lathe is also composed of headstock, tool rest, feed drive system, bed, hydraulic system, cooling system, lubrication system and other parts.There are essential differences between the feed system of CNC lathe and that of horizontal lathe in structure.
