PH80-3000 CNC Rotor Whirling Machine

Built on an integral high-strength cast bed, the CNC rotor whirling machine PH80-3000 resolves precision degradation during long screw manufacturing. The robust base provides exceptional rigidity and wear resistance for heavy metal cutting. Utilizing a 55° dovetail guide rail and a centralized lubrication system, the structure prevents low-speed crawling and guarantees stable operation. This foundation allows the CNC rotor whirling machine to maintain structural integrity across a 3000mm maximum workpiece length, accommodating demanding industrial applications seamlessly.

To achieve strict tolerances, the X and Z feed axes are driven by servo-controlled precision ball screws, delivering a linear positioning accuracy of ≤0.01mm and repeatability of ≤0.015mm. The C-axis spindle features a precision variable tooth thickness worm gear, allowing rapid side backlash adjustment. These mechanical elements ensure the CNC rotor whirling machine precisely executes 4-axis 3-linkage toolpaths. Workpieces are securely anchored using a 12-inch 3-jaw manual chuck combined with a robust mechanical locking hydraulic tailstock.

The primary milling operations are handled by the PH245W2 internal whirling head, which includes a 320mm spindle through-hole and supports a ±30° spiral angle range. Driven by a high-power frequency motor, it processes outer diameters from 90mm to 240mm, consistently achieving a surface finish of Ra3.2. Operating at speeds between 300 and 800 rpm, the multi-station clamping cutter disc uses the envelope method. This technique drastically reduces cycle times for progressive cavity pump rotors and lead screws.

A stable cutting environment is critical for high-precision manufacturing. Therefore, the setup incorporates a hydraulic double-opening automatic steady rest that provides essential support at the workpiece front end, effectively mitigating deflection. Additionally, an integrated air-blowing chip removal system and specialized conveyor rapidly clear debris from the active cutting zone. Powered by a 20KW total capacity, this CNC rotor whirling machine delivers consistent, heavy-duty production performance for complex industrial roller and worm gear applications without compromising accuracy.
