This paper introduced the manufacturing process of bore bit warm extrusion technology, main technological parameter and mold design process.
绍了钎头温挤成型工艺的研制过程、主要工艺参数的确定及模具设计过程。
The trajectory of bore hole is proved to be formed by the resultant displacement of the bit instead of the resultant force.
由此得出，决定井眼轨迹的是钻头合位移方向，而不必是合力方向。
