This machine tool is specially used for processing cylindrical deep hole workpieces, such as the spindle hole of the machine tool, various mechanical hydraulic cylinders, cylinder cylindrical through holes, blind holes and stepped holes. The machine tool can not only undertake drilling and boring, but also rolling processing. The internal chip removal method is adopted during drilling. The machine tool bed has strong rigidity and good precision retention.
