Mitarbeiter der KNOLL Maschinenbau GmbH montiert Minimalmengenschmiersystem ControLube

KNOLL MQL system ControLube unites the advantages of the previously-common single- and dual-channel MQL systems. In addition, this innovative technology offers special features with great user benefits.

Mixing chamber

Areas of application

The KNOLL ControLube is a minimum quantity lubrication system for almost all manufacturing processes with geometrically determined cutters. It combines features and applications of the existing 1-channel and 2-channel systems.

The modular setup and its unique technique makes the machine suitable for:

  • Up to 8 spindles in parallel or 3 spindles in independent individual operation
  • Simple manufacturing processes with external or internal supply
  • Ambitious manufacturing processes, with which at least one of the following criteria applies: mass production, deep-hole drilling, thread molding, high revolution speed, many tools, small tools, monolith tools, transfer line, automotive, aerospace, tool manufacturing


  1. The MQL system supplies air and oil to the mixing chamber in separate hoses
  2. The injector injects oil with high pressure
  3. Injected oil gets mixed with supplied air into a fine aerosol
  4. The aerosol afterwards flows through the following components
    • Rotary feedthrough
    • Fixed spindle tube
    • Tool holder
    • Tool
    • Outlet at machining point



High pressure injection technology

• High process reliability through precise dosage and short reaction times

• No recalibration needed

Modular design with Plug-and-Play

• Need-based configuration

• Easy extensible in case of changing requirements

Separately adjustable oil and air supply

• Low compressed air and oil consumption

• High tool lifetimes

• High process reliability

• Short processing time

Air pressure increase up to 20 bar

Improved chip transport and secure lubrication for small tools

Direct machine connection via ProfiNet or ProfiBus

• Quick and variable NC programming

• Little adaptation effort

• Very user-friendly

Fixed spindle tube, therefore no influence of the centrifugal force on the aerosol

Highest rotational speeds possible
