Problems solved by technology
[0002] Parts with small-diameter obliquely long holes are difficult to process and have high positioning accuracy. Generally, drilling machine tools are used for processing. The machine bed is divided into two parts. The space is large, the drill bit is easy to loosen, and the sealing and locking effect is poor. Moreover, due to the small hole diameter, the material of the twist drill can only be high-speed steel. When processing high-alloy structural steel materials, it is difficult for the deep hole cutting fluid to enter, and the heat dissipation is difficult. Is the drill bit easy to wear? For the processing of slender inclined holes, twist drills are used for processing. The drill bit is slender and has poor rigidity. It is difficult to guarantee the accuracy of the hole. The center deflection is large, which brings the phenomenon that other parts in the hole are easy to be damaged during the processing. Occurs, quality is difficult to guarantee
