Conprofe’s unwavering pursuit of quality and innovation has culminated in a unique core technology system for Ultrasonic-Green CNC Machine Tools—the “MUSCLE”. It integrates Minimum Quantity Lubrication (“M”), Ultrasonic Machining (“U”), Supercritical CO2 Cooling (“S”), Cryogenic Air Blasting (“C”) and Liquid Nitrogen Cooling (“L”) for Efficient & Eco-friendly (“E”) high-end manufacturing, which can be flexibly combined and adjusted based on material properties and machining requirements. With the combination of five core technologies, Conprofe has solved long-standing industrial challenges from suppressing workpiece microcracks and reducing friction coefficients to lowering cutting force and temperature saving energy and reducing carbon emissions. This has significantly enhanced production efficiency improved ecological sustainability and realized truly efficient, high-quality green machining.
Minimum Quantity Lubrication (MQL)
1. Technical Principle:
Atomize the mixture of compressed air and minimum lubricating oil to micron-sized aerosol particles
Aerosol particles rapidly penetrate the cutting interface to form a film for lubrication
Effectively reduce the friction coefficient and realize efficient cutting lubrication
2. Product Features:
Suitable for through-spindle coolant delivery
Fast-acting suspended oil mist aerosol particles system
Automatic lubricant flow adjustment for tool changes
Optional air booster system to ensure sufficient pressure and enhance MQL mist quality
Supercritical CO2 Cooling Technology
1. Technical Principle:
It transforms supercritical CO2 fluid into a low-temperature medium (-78°C) for cooling, and the low-temperature medium will rapidly expand, absorb heat and form low-temperature dry ice particles and CO2 gaseous mixture to achieve rapid cooling and lubrication to the cutting area.
2. Product Hightlights:
Low-temperature cooling (-78°C) for efficient and clean cutting of various hard-to-cut materials
Spray Medium: Low-temperature CO2 (gas / dry ice particles)
Cooling temperature: Minimum -78℃
3. Technical Advantages:
Lower Cutting Temperature: To make high-efficient cooling performance on the machining area by blasting it with cryogenic gas as cool as -78°C
Neater Machining Environment: To avoid cutting fluid splash and oil fumes, leading to clean and tidy work site, which is conducive to the workshop environment
Longer Tool Life: To reduce friction between tool, workpiece and chips, thus extending tool life
Better Surface Quality: To effectively reduce burrs by low-temperature cutting, thus improving the workpiece surface quality
Higher Machining Accuracy: To reduce machining residual stress by low-temperature cutting and avoid grain boundary distortion and white layer, thus ensuring the machining accuracy
Cryogenic Air Blasting Technology
Air Blasting offers an innovative machining solution that utilizes cryogenic air (-10°C to -60°C) combined with minimal plant-based lubricant to replace traditional cooling lubricants. By blasting cryogenic air directly onto the cutting zone, it effectively reduces the cutting temperature and minimizes tool wear. The mixture of a small amount of lubricant with cryogenic air further enhances lubrication, suppresses heat generation and significantly extends tool life.
Key Advantages:
Advanced Compression Refrigeration Technology for generating cryogenic air at -10°C to -60°C.
Fully automated PLC-controlled system with precise outlet temperature adjustment.
Integrated Minimum Quantity Lubrication (MQL) technology for mixing minimal lubricating oil into cryogenic air to achieve effective cryogenic lubrication.
Specialized piping for delivering cryogenic air and lubricating oil, enabling efficient low-temperature transfer.
Dedicated nozzles for the precise delivery of cryogenic air and lubricant mixtures to the cutting zone, ensuring superior cooling efficiency.
