Product Description

Vertical Fine Boring-Milling Machine 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 apeed, so it's can achieve of stepless speed change. Electricity of the machine are designed for PLC and man-machine interaction.
