Minimal Quantity Lubrication (MQL)

Minimal Quantity Lubrication "MQL" may be in many cases a good alternative for cutting and non-cutting metal forming. Thanks to the excellent quality of our oil-free, environmentally-friendly processing fluid ISOmist® and the sprayers and nozzles co-developed by us, processes and applications with actual minimal quantity lubrication have been successfully implemented which were previously considered unsuitable for such systems. The devices are easy to install and simple to use. Most of the machines offered on the market can be retrofitted. The atomization (nebulization) of the fluid takes place right at the nozzle and can be precisely adjusted to the needs of the user. All devices, except for the SprayUnit MINI, can be expanded modularly at any time and the single pumps can be individually controlled if required. With our devices, we do not work according to the so-called "Venturi principle", but with an environmentally friendly, quantity-regulated and low-aerosol pump solution!

ISOmist® is not subject to labeling, free from mineral and vegetable oils and can be washed with water. No problematic mist or aerosols are formed when used correctly.

Typical applications are the use in milling, turning and drilling machines and all kinds of sawing machines. It can also be used in bending and forming machines, for steady rest lubrication in roll grinders and to lubricate and cool customized and specialized machines of all fields with varied materials. It is recommended where ever cleanliness, environmental protection and the protection of employees are of high importance.

Why change to dpi Minimal Quantity Lubrication "MQL"?

  • Clean and safe work environment
  • Cost reduction
  • Higher productivity, more process liability
  • Longer tool life
  • Improvement of surface quality on the workpiece
  • Significant reduction in coolant consumption
  • Dry chips
  • No oil mist suction is required anymore
  • The usual disposal problems do not apply
  • The existing machine park can be retrofitted
  • No harmful vapors
  • If the nozzles are optimally set a costly cleaning can be avoided in many cases
  • Easy, quick and simple installation
  • Additional fluid pumps can be retrofitted at any time (except SprayUnit-MINI)
  • No more restrictions in line length, as with injector technology, which is especially important for special machines
  • Fluid and machine are from a single source and therefore are perfectly matched to each other

ISOmist® + ISOmist®09

ISOmist® is a special metalworking fluid for minimal quantity lubrication (MQL), for fine atomization for the high-speed cutting, grinding and cutting. It has extremely good lubricating properties and can be used for the machining of almost all metals including special steels, chrome and nickel alloys, titanium, Hastelloy, copper, brass, aluminum and many others. The product is preferably used where high demands are placed on surface quality as well as on process reliability.

ISOmist® convinces with further good features:
  • 100% water soluble
  • biodegradable
  • free of solvents, oils, chlorine and other substances that are hazardous to the environment and to the health of employees
  • produces minimal fog and is otherwise practically odorless
  • tested in accordance with Boeing Specification BAC 5008, sections 12.1 to 12.5, and is therefore also suitable for use in the aerospace industry
  • it is not a burden on the machine and the environment
  • no dangerous goods
ISOmist®09 is a metalworking fluid for minimal quantity lubrication (MQL) especially for "steady rest lubrication" during roll grinding, fine atomizing for HighSpeedCutting, grinding and cutting. It dissolves completely into other cooling lubrication systems on water basis without affecting it. It is, for example, perfectly compatible with our grinding solutions SGF®03 and SGF®03 BM. If too much applied fluid gets into the circuit of the grinding water, it is not affected or lowered in the pH value. The fluid is completely dissolved.

ISOmist®09 It has extremely good lubricating properties and can be used for the machining of almost all metals including special steels, chrome and nickel alloys, titanium, Hastelloy, copper, brass, aluminum and many others. The product is preferably used where high demands are placed on surface quality as well as on process reliability.

Practical experience has shown that residues of ISOmist®09 on the surface of workpieces, have no impairment during subsequent welding or even painting, in most cases the belated "washing" can be waived (cost reduction).

ISOmist®09 convinces with further good features:
  • 100% water soluble
  • biodegradable
  • free of solvents, oils, chlorine, phosphorus and other substances that are hazardous to the environment and to the health of employees
  • produces minimal fog and is otherwise practically odorless
  • tested in accordance with Boeing Specification BAC 5008, sections 12.1 to 12.5, and is therefore also suitable for use in the aerospace industry
  • it is not a burden on the machine and the environment
  • no dangerous goods

MQL SprayUnit – LC 1.2 / 2.2 liter

One of our most popular spraying units is the space-saving, cost-effective and expandable SprayUnit-LC minimal quantity lubrication (MQL), specially designed for use with our ISOmist®, but also suitable for all lubricants up to a viscosity of 2000 cSt!

One, two or four fluid pumps control the exact amount of fluid required from 0 mm³ to 41 mm³. The dosage of fluid can exactly be reproduced. The unit is 100% pneumatically controlled. The fluid is first nebulized at the spray nozzle with compressed air and then brought to the process site. Harmful aerosols and spray mist are thereby prevented.
Both, the quantity of fluid and compressed air can be adjusted separately at any time, depending on the process requirement and operational conditions. In contrast to the SprayUnit-ECO, the pump modules are not protected by a housing, but are always freely accessible.

MQL SprayUnit – ECO 1.2 / 2.2 liter

The professional SprayUnits-ECO for all types of minimal quantity lubrication (MQL), in a stable, lockable metal housing is dust and splash-proof. It was specially designed for use with our ISOmist®, but also suitable for all lubricants up to a viscosity of 2000 cSt!

From two to ten fluid pumps, if required even more, control the exact amount of fluid required from 0 mm³ to 41 mm³. The dosage of fluid can exactly be reproduced. The unit is 100% pneumatically controlled. The fluid is first nebulized at the spray nozzle with compressed air and then brought to the process site. Harmful aerosols and spray mist are thereby prevented.
Both, the quantity of fluid and compressed air can be adjusted separately at any time, depending on the process requirement and operational conditions. In contrast to the SprayUnit-LC, the pump modules are protected by a housing.

MQL spray nozzle

Variable spraying elements or nozzles for general metalworking for dispensing and nebulizing the dosed quantity of fluid to the process point. The spraying elements (long) consist of variable, semi-rigid or rigid extensions (300 mm total length) which carry at the end the actual spraying device/nozzle and can be fastened by magnetic bases or screws. This way it is possible to reach difficult to access spraying points easily and the nozzles can be adjusted to the respective requirements.
The spraying element "Short Length" is a space-saving universal alternative, which has an extremely short structural length (57 mm) and consists only of the actual spray nozzle and the push-in-fitting.
All spray nozzles are connected via push-in-fittings (6mm) to the fluid supply of the SprayUnits.
