Numerically controlled lathe with balance corrector

In a combined machining lathe having fixed-tool turning-workpiece lathe function and a drilling and or milling function, a numerically controlled lathe with a balance corrector, comprising:

• a sensor for detecting a rotation angle of a main spindle;
• at least one vibration sensor mounted on a headstock and a tailstock;
• means for calculating an imbalance amount and phase of a workpiece from signals output from the sensor and the vibration sensors;
• and
• means For producing a program For carrying out equivalent balance correction machining using the drilling and/or milling function from the obtained imbalance amount and phase.

In a numerically controlled lathe having fixed-tool turning-workpiece lathe function and a non-round machining function utilizing, a synchronous X-axis feeding of a tool post with a rotation of a main spindle, a numerically controlled lathe with a balance corrector, comprising:

• a sensor for detecting a rotation angle of the main spindle;
• at least one vibration sensor mounted on a headstock;
• means for calculating an eccentric amount at an equivalent balance correction from an imbalance amount and phase of a workpiece, which are calculated from signals output from the sensor and the vibration sensors;
• and
• means for producing a program for carrying out balance correction eccentric machining using the non-round machining function from the obtained eccentric amount.
