Vertical Fine Boring-Milling Machine T7240


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.
