The bed of machine has rectangle guide way which has high abrasive resistance after quenched. The feeding lead screw is equipped between the two guide way.The fixture of the guide carriage and clamping of workpiece is made by the servo motor and it is safe and reliable. The spindle of guide carriage and machine spindle has high concentricity and rotation precision.It is easy to change the guide bush. The machine is a kind of deep hole boring machine with easy to operate and control, high efficiency.
