CNC lathes and turning centers are high-precision, high-efficiency automated machine tools.
Equipped with multi-station turret or power turret, the machine tool has a wide range of processing technology.
It can process linear cylinders, diagonal cylinders, arcs and various complex workpieces such as threads, grooves and worms.
It has various compensation functions such as linear interpolation and circular interpolation, and has played a good economic effect in mass production of complex parts.
“CNC” is an abbreviation for Computerized Numerical Control in English.
The CNC machine tool automatically processes the machined parts according to the pre-programmed machining program.
The machining process of the parts, process parameters, tool trajectory, displacement, cutting parameters (spindle revolutions, feed, backfeed, etc.) and auxiliary functions (tool change, spindle forward, reverse, the cutting fluid is turned on and off), and is programmed into a machining program according to the instruction code and program format specified by the CNC machine tool, and then the contents of the program list are recorded on the control medium (such as punched tape, tape, disk, bubble memory), and then input into the numerical control device of the CNC machine tool to command the machine tool to machine the parts.
This process from the analysis of the part drawing to the preparation of the control medium is called the preparation of the NC program.
The difference between CNC machine tools and ordinary machine tool parts is that CNC machine tools automatically process parts according to the program, while ordinary machine tools are operated by people.
We can achieve the purpose of processing different parts by changing the program that controls the movement of the machine.
Therefore, CNC machine tools are especially suitable for machining parts with small batch sizes and complex shapes and high precision.
Since the CNC machine tool needs to machine the parts according to the program, after the programmer has programmed the program, it is input into the numerical control device to direct the machine tool work.
The input to the program is through the control medium.
