What is Rotor
PCPC rotors (such as progressive cavity pump rotors) are core components in petrochemical, wastewater treatment, plastic machinery, and other industries for conveying high-viscosity/particulate fluids. Its geometric characteristics are spiral curved surfaces, multi-wire threads, high-precision mating gaps, and the commonly used materials are stainless steel, alloy steel and other high-strength metals. Common machining risks include leakage due to insufficient thread accuracy, rough surfaces affecting fluid transfer efficiency, and workpiece deformation caused by prolonged processing.
Rotor Whirling Core Pain Point
There are three major bottlenecks in the processing rotor of traditional vertical machining centers:
- Inefficiency: A single piece takes 4-6 hours, and the order delivery cycle is long, missing market opportunities;
- Unstable quality: poor surface finish (Ra≥6.3), large fluctuations in thread accuracy, scrap rate of more than 5%;
- High cost: high equipment occupancy rate, long manual duty time, high maintenance costs, and unit workpiece cost exceeding expectations.
Rotor Whirling Process
Blank → roughing→ finishing (cyclone milling), surface treatment→ quality inspection →
Key points of the sub-link
- Blank preparation: Select forgings/casting blanks to ensure uniform material density and reduce the risk of subsequent deformation;
- Rough machining: use ordinary lathe to remove the allowance (about 70%), and reserve 0.5-1mm allowance for finishing;
- Finishing (core link):
- Equipment: PH50-1000 CNC cyclone milling machine (4-axis 3-linkage, Siemens 808 controller);
- Process: external cyclone milling, through axis synchronous control to achieve multi-wire thread one-time forming;
- Tools: Customized carbide tools (clamp-type tool holders), frequency conversion cyclone milling head (600-1200rpm) to ensure cutting stability;
