Energy and cost savings through MQL
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 of these devices are not needed when using 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 into 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.
