The MiQueL minimal lubrication system

Operating principles and applications

25 FEBRUARY 2020

In the industrial lubrication sector, we seek to develop technologies with the aim of achieving both savings in terms of costs and a greater protection of the environment.

The minimal lubrication system (MiQueL) is the solution that meets these requirements, with a technology that marks a turning point compared with the past.

Tool machining generally makes use of coolant, a fluid designed to reduce the friction and wear of the forces and energies in play, remove swarf from the work area, and protect the surface from possible corrosion.

Aside from these features, the use of a coolant causes problems caused by the heavy use of lubricant, which dirties the working environment and must then be disposed of.

To solve these issues, a minimal lubrication system (MiQueL) has been designed and developed, a new technology that will replace the traditional cooling or full oil system within a working environment.

What is minimal lubrication (MiQueL)?

The aim of minimal machining is to substitute traditional cooling and pure-oil immersion systems in working environments with a controlled compressed air flow, which generates minimal amounts of oil in a very thin “aerosol” format.

The aerosol mixture is directed directly onto the tool’s cutting surface via a nozzle, and guarantees high machining performance by eliminating swarf.

Characteristics and functioning of the MQL system

The MiQueL modular system has been designed for lubricating machine tools in general, machines for cutting and folding sheet metal, steelworks, and anywhere that a precise and calibrated lubrication with control of all functions is required.

It’s a ready-to-use solution for external tool lubrication, which enables up to 8 connected elements to be inserted that can be excluded or activated at any time by means of the integrated solenoid valve, and also permits the individual control of both oil and air flow rates for each individual element.

What are the benefits?

There are many advantages that come with the use of minimal lubrication:

Reduced machining time from 25% to 80%, as well as a reduction in the consumption of water and oil
Increased tool life, with a subsequent increase in productivity
No more need for coolant:  the workplace will be a zero-impact environment
Improved finish and tolerance of pieces: the piece is covered with a layer of oil to prevent rusting.
