The invention discloses a high precision thread trimming device and a high precision thread trimming method for an embroidery machine. The device comprises a plastic cutter driving device and a thread trimming device, wherein the plastic cutter driving device is arranged at the upper side of a faller; the thread trimming device is arranged at the lower side of the faller; the plastic cutter driving device comprises a plastic cutter motor; a position sensor and an eccentric wheel are respectively arranged on the periphery of a drive shaft of the plastic cutter motor; the eccentric wheel is connected with a swing rod with a sliding chute at one end by a pin roller; a stationary shaft connected with a motor base is arranged in the middle of the swing rod; the other end of the swing rod is connected with a pull rod driving a plastic cutter by a connecting rod. The device has the beneficial effects that the exact position of the plastic cutter when going back is determined via the position sensor on the periphery of the drive shaft of the plastic cutter motor, thus achieving high precision control of the thread trimming length and avoiding technical defects caused by main shaft speed fluctuation.
