Cage type boring tool

The utility model discloses a cage type boring tool which comprises a cylinder body, a boring head and a boring head, wherein one end of the cylinder body is open, and the other end of the cylinder body is closed; a mounting hole is formed in the closed end of the cylinder and used for being assembled and fixed with a boring machine spindle. The open end of the cylinder is used for installing a boring cutter component and a ball seat. Through the cage type boring tool and the tool apron and the ball seat matched with the cage type boring tool, the machining depth of the boring machine is increased, the damping effect is obvious, and the rigidity and the stability are very good. 本实用新型公开了一种笼型镗削工装，包括：一端为开口、另一端为封闭的筒体；筒体的封闭端开设安装孔，用于与镗床主轴装配固定；筒体的开口端用于安装镗刀部件及滚珠座。通过笼型镗削工装和其配套的刀座、滚珠座，镗床的加工进深加长，且减震效果明显、其刚性、稳定性非常好。
