An apparatus and method for ultrasonically forming a surgical suture tip from a length ol unfinished surgical suture material. The apparatus includes a first tipping die having a first lace for contacting a portion ol the length ol unfinished surgical suture material. A second tipping die having a second lace is also provided. At least one mechanical actuator is provided for moving the first lace ol the first tipping die toward the second lace ol the second tipping die. A second actuator vibrates at least one ol the first and second tipping dies at an ultrasonic frequency ol about 15 KHz to 70 KHz. The method ol ultrasonically forming a suture tip comprises the positioning a surgical suture between the first lace ol the tipping die and the second lace ol the tipping die then vibrating the dies at an appropriate frequency.
