Description

Technical Field

[0002] Deep hole drilling is a machine tool used for deep hole processing. It has the characteristics of fast, accurate and stable deep hole processing. It is widely used in mold manufacturing, machinery manufacturing, automobile manufacturing and other industries. The processing hole diameter range of the machine tool is 2.5-120mm, the effective processing depth can reach 2200mm at one time, and the maximum load of the workbench can reach 17 tons. This machine adopts advanced CNC operating system, with high drilling efficiency, which is more than 6 times faster than the general radial drilling machine. Compared with the traditional radial drilling machine, Taili deep hole drilling has unique advantages;
