The machine tool is a deep hole processing machine tool, which can complete the drilling, boring and machining of large diameter heavy parts. When the workpiece is processed, the workpiece is rotated at a low speed, and the cutter is told to rotate and feed. When drilling with BTA in chip technology, boring the boring bar for cutting fluid forward (Chuang Touduan) row of cutting fluid, cutting chip technology; nesting by efflux chip technology, equipped with special tool, a knife bar and a special tool clamp. According to the need of the processing, the machine is equipped with the boring bar, the cutter can be rotated and fed.
