Product Description
Vertical fine boring-milling machine, model: T7240
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
