This machine is specially for rotors processing of screw motors in Oil industry.This machine is specially for rotors processing of screw motors in Oil industry. Adopting clamped cemented carbide dick milling cutter, to do envelope milling processing on the workpiece helicoid surface, fully finished by one time. It is a main equipment in screw motors device, also a high efficient production machine for screw pump rotors and stator mandrels.
1. Siemens CNC system, four-axis linkage.
2. Machine base use large span(800mm) frame, high intensity, wearing-resisting casting iron. The machine is horizontal type, with good quality on rigidity and aseismicity.
3. Milling head is driven by power motor, synchronous belt and gears(frequency control of the motor speed), which make it with strong strength and good frame rigidity.
4. Z-axis direction movement is driven by servo reducer and Germany precision racks, avoid the accuracy erro caused by ball screw drooping. Adopts electrical double anti-backlash technique, hold on the location accuracy.
5. Workpiece clamping adopts automatic hydraulic locking tech, special adjusting frame, make sure the machine can get good accuracy while milling processing.
6. Adopts advanced cutter head device, making the tool testing easily.
7. Full safety guard, automatic chips removing.
