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

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.

Data exchange:

• PROFIBUS

• PROFINET

• digital I/O

Excellent solutions

Aerosol generation

The lubricant medium used for MQL is a very fine mixture of compressed air and micronized oil droplets, sized up to 1 micron, defined as “aerosol”. The aerosol is conveyed to the lubrication point through flexible pipes. The absolute volumetric flow rate is optimally regulated by the MQL system. Depending on the different processing needs, the concentration of the oil particles can be increased or decreased separately for each tool through the machine CNC.

Lubricating oil

The recommended MQL lubricants are exclusively of synthetic origin (or bio-based). System filling can be manual or even fully automatic, requires no maintenance and is totally safe.

A system for the future: suitable for every application

MQL systems can be used on any type of modern CNC machine tool and almost in all mechanical processes:

• Transfer machines

• Portal milling machines

• Turning and milling centers

• Flexible production systems

• Double spindle machine tools

• Multi spindle heads

Our team of experts can develop the best solution for each tool and material, to meet the requirements of each single user.
