According to the present invention, water or air is supplied to the first tool and the second tool by the first nozzle portion and the second nozzle portion, so that processing is performed from heat and friction generated during processing of the processing material Protects materials and tools, improves processing accuracy, and prevents the flow of processed chips, water, or air from the processed material into the mechanism operation part of the base by the discharge unit and shut-off unit, thereby increasing the life of the device The present invention relates to an artificial tooth processing apparatus capable of preventing the first tool and the second tool from colliding with each other by the tool collision prevention control unit during machining of a workpiece. [Selected figure] Figure 3本発明は、第１のノズル部と第２のノズル部とにより第１の工具と第２の工具とに水または空気が供給されることで、加工素材の加工時に発生する熱と摩擦から加工素材と工具を保護し、加工精密度を向上させ、排出ユニットと遮断ユニットとによりベース部の機構作動部に加工素材の加工チップや水または空気が流入することを防止して装置の寿命を増大させ、工具衝突防止制御部により加工素材の加工中に第１の工具と第２の工具とが衝突することを防止できる人工歯加工装置に関するものである。【選択図】図３
