Cylinder Boring Machine T7240

image.png

The machine 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
