This series CNC lathe can be mated with FANUC, SIEMENS or other Chinese CNC system, with programmable control and CRT display. AC servo motor is used for Z axis and X axis feeding, pulse encoder is used for feedback. The bed guide way is made of high-strength resin iron casting and ground after ultrasonic frequency quenching. The guide way carriage is pasted with plastic so
as to reduce friction.
The contacting area between the headstock and the machine bed is large. After scraping and grinding, the ability to bear the cutting force generated of heavy cutting of the workpiece is furtherenhanced, and the stability of the machine is also strengthened. The main motor of the machine can be chosen a high-power frequency converting motor and adopts three supports structure with strong rigidity. After the simplificationof the transmission at the head of the machine tool, it can provide enough torque at low rotation speed to cut large and heavy workpieces. Especially when
machining workpiece blanks, it ensures the normal operation of the machine tool with large cutting amount. When shifting to low gear the main motor can work at full power, which provides the necessary premise for fast machining.
This machine has a wide cutting range, can process outer circle, inner hole and end face. Grooving, machining taper surface, chamfering, conical or cylindrical thread and arc surface.
