Introduction
Parameters
The characters of T2120G deep hole drilling and boring machine as belows,the machine bed guideway is double rectangle guideway which is quenched and has high anti-brade ability.The feeding rack is installed between the bed guideway.The feeding rack is installed between the bed guideway.The feeding and movement of the guide carriage is controlled by servo motor.dive by gear rack and has high rigidity and easy to control.The ouput axial of feeding AC servo motor is equipped with Germany MAYER torque limit device to ensure the asfe of machine,tools and workpiece.The main motor is variable frequency motor.The speed is change stepless by three grade so the ability to fit is high.The machine is special machine for cutting cylinderial deep hole workpiece.It used for drilling and borning processing of cylindrial workpiece.Used the high effect composed tools such as csrape and rolling composed automatic expand and shrink tools made by Germany Wenaroll Company or our company,the machine can process the cylinder with high speed and high efficiency.
