Numerical control vertical type boring machine

The utility model discloses a numerical control vertical type boring machine which comprises a digital control system, a main shaft system, a feeding system, a base and an upright column. The numerical control vertical type boring machine is characterized in that the main shaft system comprises a main shaft servo motor, a synchronous belt, main shafts, a knife handle and a boring cutter. The main shaft is in a double-main-shaft structure, and the main shaft servo motor simultaneously drives two main shafts through the synchronous belt. The two main shafts are the same in height and arranged side by side. The numerical control vertical type boring machine has the advantages that the numerical control vertical type boring machine adopts the double-main-shaft structure, can achieve machining of boring and drilling for two holes which are different in size on the same plane under the control of the digital control system and matched with the feeding system, and is reasonable in the whole structure, small in friction coefficient, and high in feeding speed, and the like.
