MWM MQL tools systems
MQL technology for minimal internal tool lubrication.
Single-channel MQL systems
Internal MQL for Tools
Technological developments aimed at shortening the manufacturing processes, even by eliminating unnecessary steps, are fundamental to produce faster and efficiently.
Dry machining with MQL technology offers enormous potentials for process optimization, leading to valuable competitive advantages.
MQL generates less heat during the cutting process. As a result, the tool lasts longer, the cutting speed increases, the surface quality improves and the entire machining process is completed in a shorter time and at lower costs.
With a consolidated know-how and application experience, MWM has developed a complete family of systems for internal MQL, really reliable and for high performance.

Energy and cost savings through MQL
Better on principle
MQL-Systems replace conventional coolant in the modern machining processes. The use of a special technology greatly reduces the friction between workpiece, chip and tool. As a result less heat is produced, the tools last longer, the cutting speeds increase and the entire machining process is completed in a shorter time and at lower costs. Depending on the specific machining process, savings up to 30% can be achieved.
Dry machining with MQL technology offers enormous savings potentials in series production. The traditional method based on coolant requires several devices, i.e. emulsion cooling and cleaning, wet chips processing and waste water treating. All these devices are not needed when using MQL.
MQL system benefits at a glance:
- up to 50% energy saving, compared to coolant
- Minimized lubricant consumption (on average: 20 ml/h)
- No water consumption
- Chips and machined parts nearly dry (no oil soiling)
- Elimination of the metalworking fluid (emulsion) system
- No need to prepare and dispose of used metalworking fluid
- No thermal shock on the tool cutting edge
- Longer tool life
- Higher cutting speed
- Better surface quality
- Perfect execution of deep holes, even with L / D > 30
- Complete visibility over the on-going process (no scattering)
- Clean working environment, compliance with health and environmental regulations
Energy saving with MQL
Energy required by a machine tool, potential savings resulting from the use of MQL technology.
Cost savings with MQL
Innovative technologies:
Aerosol supply
The aerosol is generated inside the MQL system using algorithms that regulate the technical generation process. The aerosol is conveyed to the lubrication point, either through flexible pipes and channels inside the machine or through external side nozzles. The oil particles get condensed in small droplets and are precisely addressed to hit the tool cutting edge.
System control
The individual volumetric flow rates are perfectly regulated by a control device inside the MQL system and all the data for process monitoring are transferred to the machine control system. A particular advantage of the MQL is the instrumental response time of less than 0.1 sec. In this way the systems can operate in a total safe mode, even on very dynamic and fast machine tools.
