The T7240 is mainly use for boring large and deep holes , (such as:cylinder body of locomotive ,steamship,car) also can milling the surface of the cylinder.
*Servo-motor control the table longitudinal move and the spindle up and down
Spindle’s whirl use variable-frequency motor to adjust the speed ,so it’s can achieve of stepless speed change
*Electricity of the machine are designed for PLC and man-machine interaction
