The drill bit is usually connected to the drill pipe by threads, and the connecting parts are all circular cross-sections. Its rigidity is higher than that of the gun drill, and the production efficiency is 2-4 times that of the gun drill. However, due to the limitation of the chip removal space of the tool system, it is mainly used for the processing of holes with a diameter of ?≥16mm, and the tools cannot be reground. The workpiece is rotated or fixed, and the drill pipe is rotated and fed.
The feed guide adopts rolling guide, which has high hardness, stable movement and long precision retention time. There are various types of workpiece clamping, such as double chuck, chuck with hydraulic steady rest, inner cone top plate, etc.
The preferred equipment for deep hole machining of large quantities of rotary shaft parts, suitable for mining machinery, machine tools, molds and other industries.
