The XKS230-6000 CNC Whirling Milling Machine is a high-precision machining device specially designed for the rotors of progressive cavity pumps:
- Rigid Structure: Integral high-strength cast machine bed plus three horizontally arranged guide rails (quenched hardened rails), featuring excellent deformation resistance.
- Precision Drive: Precision ball screws for X/Z axes paired with servo motors, with a repeat positioning accuracy of 0.03mm.
- High-efficiency Milling: Internal cutting milling head, powered by a 7.5kW variable-frequency motor for ample driving force.
- Low Maintenance: Oil-lubricated spindle bearings on the headstock, eliminating the need for daily maintenance.
- Intelligent Control: Equipped with Syntec CNC system, supporting real-time monitoring and parameter adjustment.
- Convenient Chip Removal: Integrated Yanshan chip removal machine and high-pressure water pump for forced cooling, ensuring smooth chip discharge.
- Safety Protection: Semi-enclosed protective cover combined with Delixi electrical components to guarantee production safety.
The XKS230-6000 CNC Whirling Milling Machine is specially designed to address the pain points in long rotor machining:
- Supports the machining of ultra-long rotors up to 6 meters (maximum workpiece length: 6000mm).
- Repeat positioning accuracy reaches 0.03mm, ensuring high precision of the helical surface.
- Single milling head configuration boosts efficiency by 35%.
- Oil-lubricated bearing design cuts daily maintenance costs by 80%.
- Customizable process solutions are adaptable to multiple scenarios such as petroleum, chemical engineering, and sewage treatment.
Purpose: Progressive cavity pump rotors are core components for fluid transfer, widely used in fields such as petroleum drilling (high-viscosity crude oil/sand-containing mud), chemical engineering (acid-alkali corrosive fluids), and sewage treatment (sewage containing solid particles).
Materials: Stainless steel, high-temperature alloys, corrosion-resistant alloys, etc. (customized according to application scenarios).
Geometric Characteristics: Helical profile, large length-diameter ratio (maximum length 6m), and prone to deformation.
Common Risks: Deformation during machining, seal failure caused by insufficient precision, and tool jamming due to poor chip removal.
- No Suitable Equipment: Conventional equipment cannot process 5-6-meter-long rotors, resulting in the loss of high-value orders.
- Low Efficiency: Long machining cycles of traditional lathes lead to delayed order delivery.
- Cumbersome Maintenance: Bearings require frequent lubrication, leading to high downtime costs.
Blank (forging/casting) → Rough Machining → Finish Machining
- Rough Machining: An internal cutting milling head (powered by a high-output 7.5kW variable-frequency motor) is adopted for rapid stock removal. Core equipment: Universal 4-jaw chuck (for stable clamping of long rotors), Yanshan chip removal machine (equipped with a high-pressure water pump for forced cooling, ensuring smooth chip discharge).
- Finish Machining: An internal cutting milling head driven by precision ball screws on the X/Z axes (repeat positioning accuracy of 0.03mm) ensures the helical surface tolerance is ±0.05mm. Core equipment: Syntec CNC system.
- Cooling & Chip Removal: The chip removal machine is integrated with a high-pressure water pump, which prevents chip accumulation and tool jamming, and extends tool life by 20%.
- Efficiency: 35% higher than that of conventional equipment
- Scrap Rate: Reduced from 10% to 3%
- Maintenance Cost: Cut by 80% (oil-lubricated bearings eliminate the need for daily maintenance)
- Cycle Time: Machining cycle for 5.5-meter rotors shortened from 20 hours to 2 hours
Case Study: A leading petroleum drilling equipment manufacturer once lost 30% of its orders due to the inability to process rotors over 5 meters long. After purchasing the XKS230-6000, it successfully secured orders for 6-meter-long crude oil transfer rotors, improved efficiency by 35%, and increased annual revenue by $2 million.
Applicable Scenarios: Petroleum drilling and production, corrosive fluid transfer in chemical engineering, and transfer of particle-containing media in sewage treatment.
