FULL/AUTOMATIC DOUBLE END CHAMFERING MACHINE

摘要

PURPOSE:To obtain a constant chamfered volume at both ends of a material being cut by allowing chamfering cutters provided at both ends of the material to slide in the axial direction of the material and performing chamfering operation after ensuring that both the chamfering cutters are in contact with the material. CONSTITUTION:When a material being cut 3 is fed from a constant-volume - feed mechanism and detected by an adjacent switch 45, a vise is operated by a control device 110 to clamp the material 3 being cut. Then, the quick-feed distance and cut-feed distance of slide motors 47, 48 are calculated based on the diameter, length, and chamfering conditions of the material, and drill units 40, 41 are quick-fed and out-fed by the slide motors 47, 48. After both chamfering cutters 49, 50 of both the drill units 40, 41 are brought into contact with both the ends of the material and a contact signal is given, the chamfering cutters 49, 50 are driven to cut both ends of the material being cut. Consequently, there is no variation in chamfered volume of both ends and the chamfered volume is constant.
