Vertical Fine Boring-Milling Machine T7240
Features:
1. 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.
2. Servo-motor control the table longitudinal move and the spindle up and down, Spindle rotation adopts variable-frequency motor to adjust the speed, so it can achieve the stepless speed change regulating.
3. Electricity of the machine are designed for PLC and man-machine interaction.
