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.Max.boring diameterDia 320mmMax.boring depth750mmSpindle(carriage) travel1000mmSpindle speed(stepless speed change for frequency conversion)50-1000r/min(Spindle feed travel speed)6-3000mm/min(Distance from spindle axis to carriage vitical plane)500mm(Distance from spindle end-face to table surface)25-840mm(Table dimension LXW)500x1600mm(Table working slot)5 5slot(Table longitudinal travel)1600mm(Table longitudinal travel speed)6-3000mm/min(Table latitudinal travel)300mmMain-motor(Variable-frenquency motor)33HZ,5.5KWTable longitudinal travel motor (Serve motor)15NmTravel motor of spindle(Serve motor)15NmBoring dimension accuracyIT7Milling dimension accuraryIT8Rundness0.008mmCylindricity0.02mmBoring roughnessRa1.6Milling roughnessRa1.6-Ra3.2Overall dimensions2281x2063x3140mmN.W/G.W7500/8000KG
