The present invention is proposed in view of the above, blur of the shaft bone during surgery by minimizing the diameter of the increased while still sleeve rigidity for bending is not caused, muscles, reduces the interference and damage to the soft tissue, and durability provide a cutting device of the cutting system using the robot to improve the The purpose is to. Cutting device of a cutting machine using a robot according to the present invention includes a cutter cutting head is formed at an end of the shaft and the shaft is coupled to a motor provided on the robot arm, and a joint cutting machine equipped with a sleeve in which the shaft is inserted, In the cutting device, the sleeve is inserted into the shaft portion of the shaft inserted into the shaft insertion hole is formed And integrally extends on one side of the shaft insertion portion, it is formed and characterized in that it comprises a reinforcement wing which provides rigidity for the bending in the shaft insertion portion. Accordingly, a large load on the shaft in the vertical and horizontal movement of the cutting head when the procedure is working, so that the bending load on the shaft insertion portion of the sleeve repeatedly applied, even if the rigidity for bending by the reinforcing wings reinforce the entire thickness of the sleeve there is an effect that is not easily bent or deformed even if not minimized. During the procedure while still minimizing the thickness of the sleeve in this way bone, muscle, surrounding the stability of the treatment in reducing the interference and damage to the soft tissue and can enhance the effect of shortening the recovery time of the patient.본 발명은 상기 내용에 착안하여 제안된 것으로, 샤프트의 떨림 현상이 발생되지 않고 휨에 대한 강성을 증가시키면서도 슬리브의 직경을 최소화 함으로써 시술시에 뼈, 근육, 주변 연부 조직의 간섭 및 손상을 줄일 수 있고 내구성이 향상되도록 한 한 로봇을 이용한 절삭시스템의 절삭장치를 제공하는데 그 목적이 있다.본 발명에 따른 로봇을 이용한 절삭시스템의 절삭장치는 로봇팔 부분에 구비된 모터에 결합되는 샤프트와 이 샤프트의 단부에 절삭헤드가 형성된 커터와, 및 상기 샤프트가 삽입되는 슬리브가 구비된 관절 절삭시스템의 절삭장치에 있어서, 상기 슬리브는, 상기 샤프트가
