Problems solved by technology

[0003] The drilling and tapping combination machine tool of this structure adopts a rigid tapping structure. When processing large nominal diameter threaded holes on large workpieces, the process of the hydraulic cylinder and the process of the tap form mutual constraints, which can easily cause thread slippage. (thread breakage)
