Vertical fine boring-milling machine-T7240
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
