Vertical Fine Boring & Milling Machine T7240

haricteristics

 
The machine is mainly used for boring large and deep holes( such as cylinder body of loco motive, steamship and car), also can milling the surface of the cylinder.    Servo-motor control the table longitudinal move and spindle up and down. Spindle’s whirl use variable-frequency motor to adjust the speed, so it can achieve of stepless speed change. Electricity of the machine are designed of PLC and man-machine interaction.
