The deep hole drilling boring machine itself has strong rigidity, good precision and good spindle speed range. The feed system is driven by AC servo motor and can meet the needs of various deep hole machining processes. The oil cooler is tightly fastened and the workpiece is tightly attached to the hydraulic device. The meter display is safe and reliable. The following types of work can be selected: 1. Workpiece rotation, tool rotation and reciprocating feed movement, suitable for drilling and small diameter boring; 2. Workpiece rotation, the tool does not rotate only for reciprocating motion, suitable for large diameter hole And nesting processing; 3. The workpiece does not rotate, tool rotation and reciprocating feed motion, suitable for complex workpiece drilling and small diameter drilling and small diameter bore.
