In the machine tool, new technology method and U drill were adopted to machine the hole of the parts of various steer?ing knuckle forks. Through the process of drilling and boring, the hole of the parts could reach the precision of the process of drilling?expanding?hinging?boring. Because U drill was allowed to adopt higher cutting speed and feed, the machining time was greatly short?ened. Through technology analysis to these parts, the general layout and working cycle of the machine tool were expounded. The main structures and features of the machine tool were introduced. This machine tool has the characteristics of good rigidity, high precision and high efficiency.
