Why is the CNC lathe so precise, what is it?
In summary, so CNC lathes compared with the traditional lathe, the machining accuracy has been greatly improved.
3: closed-loop, semi-closed-loop feedback device, most of the current CNC lathe with such a device, this device can drive the real-time detection of the movement position, once the detection of the transmission system movement "too far" or not in place, it can this
2: CNC lathe screw feed units are um level even smaller, (1mm = 1000um)
Machine tool itself to improve the accuracy, such as precision tool holder, there is the CNC lathe drive screw and ordinary lathe drive screw is completely different, CNC lathe drive screw is used precision ball screw, motion gap and backlash
