CNC machine tools


In general,any CNC machine tools consists of the following units:

1 CNC device

2 Serve drive system:including driver and serve motor

3 Machine

As with all computers, the CNC device works on a binary principle using only two characters 1 and 0. Series of ones and zeros which is so-called machine language is the only language the computer understands. When creating the program, operators use a list of codes and keys to express the job information.

After inputting the program,CNC device will first compile it into machine language with special built in software, then the computer will calculate all the points and send out the control commands ( electronic pulse signals ) to serve drive system.

About serve drive system

Serve drive system includes drives and serve motors,which is the bridge connecting CNC device and machine.

Drives transform pulse signals sent out from CNC device into motor signals,which tell the serve motor to rotate with each pulse. The rotation of the serve motor in turn rotates the lead screw which drives the linear axis. With each step of movement, the measure device sends a signal back to CNC device which compares the current position of the drive axis with the programmed position.
