OIL DAMPING DEVICE FOR REDUCING VIBRATION OF A SPINDLE OF AN NC BORING MACHINE, CAPABLE OF REDUCING CHATTER VIBRATION

摘要

PURPOSE: An oil damping device for reducing vibration of a spindle of an NC(Numerical Control) boring machine is provided to reduce or remove vibration generating in a boring spindle during a process as a mass body generates resonance.;CONSTITUTION: An oil damping device for reducing vibration of a spindle of an NC boring machine comprises a boring spindle(100), a spindle head(200), and an oil damping device(300). The boring spindle is projected from the leading end of a spindle. The spindle head cages the one external end of the boring spindle. The oil damping device is attached to the rear end of the boring spindle and rotates with the boring spindle. The oil damping device reduces chatter vibration by absorbing vibration due to the rotation of the boring spindle.;COPYRIGHT KIPO 2012
