The KNOLL AerosolMaster 4000 Cryolub is a minimum quantity lubrication system based on cryogenic cooling technology for manufacturing processes that use geometrically defined cutting edges, e.g. on machining centers, transfer lines, turning, milling, drilling and sawing machines.

Thanks to unique ATS technology in combination with Cryolub cryogenic cooling technology, the system is ideal for demanding machining of titanium- and nickel-based alloys (e.g. implants), Inconel, composite materials (e.g. carbon) in the medical device, aircraft and energy industries.



Oil content and air pressure adjustable
as required via 30 programs

Very fine and homogeneous aerosolLow-loss lubrication
Almost dry machining

• No sticking
• Minimal cleaning of parts and machine required

Immediate availability of aerosol and CO2 at the
cutting edge as soon as spindle starts

• No wait times
• Great process reliability

Long aerosol lines up to 50 m possibleFlexible setup
Optional machine connection via ProfiBus 
or ProfiNet

• Quick and variable NC programming
• Little adaptation effort
• Very user-friendly

CO2 content adjustable as required

• Low consumption
• Optimum tool temperature
• Workpiece temperature = room temperature

Description MQL

  1. Compressed air flows into the venturi nozzle through a compressed-air control valve
  2. The venturi nozzle draws in oil from the container and mixes it with the air to form a fine aerosol
  3. Air pressure and aerosol pressure control valves define the air pressure and saturation level of the aerosol
  4. The oil/air mixture flows through, in succession, the:
    → rotary union
    → spindle
    → tool holder
    → tool
    → discharge opening(s) at the machining point(s)

Description Cryolub

  1. CO₂ supply by the customer
  2. CO₂ switchover valve: switchover valve: Disconnects the CO₂ in case of danger
  3. CO₂ control valve: Controls the cooling capacity via the CO₂ flow rate
  4. CO₂ distributor (optional): Allows additional, external cooling nozzles
  5. CO₂ switchover valve: Provides fastest response times
  6. Aerosol and/or CO₂ discharged at the tool or the external nozzle.
