The invention discloses a digital controlled
drill which comprises a base, a Y-oriented
servo motor, a Y-oriented rolling linear guide rail pair, a Y-oriented
ball screw, a Y-oriented drive nut, a Y-oriented sliding table, an X-oriented
servo motor, an X-oriented rolling linear guide rail pair, an X-oriented
ball screw, an X-oriented drive nut, a working table, a Z-oriented
servo motor, a Z-oriented
ball screw, a drive nut, a Z-oriented main shaft box, a Z-oriented rolling linear guide rail pair and a stand column. The stand column is installed on the base, the Z-oriented servo motor is movably connected with the Z-oriented ball screw through a transmission mechanism so as to drive the Z-oriented ball screw to rotate, the Z-oriented ball screw is rotatably supported on the stand column, the drive nut is movably connected to the Z-oriented ball screw through threads, the Z-oriented main shaft box is fixedly connected with the drive nut, the Z-oriented rolling linear guide rail pair is arranged between the stand column and the Z-oriented main shaft box, and the working table is located below the Z-oriented main shaft box. According to the
drill, moving strokes can be increased in the X direction, the Y direction and the Z direction, the
machining range of workpieces is widened, meanwhile, the
electric power loss amount can be reduced, cost is saved, and precise positioning and
machining of the workpieces can be achieved.
