T7240 heavy duty large CNC Vertical Cylinder Boring Machine

The main performance characteristics:
T7220B is mainly used to bore high accurate holes of cylinder body and engines sleeve and other
Accurate holes. The table longitudinal and latitudinal moving device; The workpiece fast centering device;
Boring measuring device; Also provides optional digital readout for the table's longitudinal and cross moving
accessories to serve the users.


T7220C is mainly used for fine boring high accurate hoils of cylinder boday and engine sleeve also for other
accurate holes, it can used for milling surface of cylinder. The machine can be used to boring, milling, drilling
and reaming.
The table longitudinally and cross moving devices.
The workpiece fast centering device.
Boring measuring device
The table longitudinal moving
Digital read-out device


T7240 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
*Electricity of the machine are designed for PLC and man-machine interaction
