Minimal Quantity Lubrication (MQL) Systems in Metal Cutting Excellence in Minimal Quantity Lubrication

Traditional metal machining – still in line with the times? Requirements and problems when using coolant emulsion (CE) To use CE effectively, a coolant system with recirculating pumps is required and coolant reservoirs along with the piping. Furthermore, special systems are required for cleaning or drying the workpieces, as well the swarf before recycling. Example of Flood Coolant for cooling and lubricating when mechanically machining components. Company responsibility: Occupational Health and Safety Through constant contact by employees with CE in the relevant production areas health...

Minimal quantity lubrication technology (MQL) in the metal cutting processes is in the position to combine the highest productivity with ecological and health benets. The undisputable reduction alone in the consumption of coolant emulsions makes, in many respects, improvements in the entire metal processing sector and, of course, for man and the environment. In order to assess the benets it is worth taking a look at the details. • The MQL vaporises virtually completely and immediately at the tool cutting edge. • The machining system and the workpieces remain virtually oil-free. • The swarf...

Try dry … Dry using minimal quantity lubrication technology instead of drying ! The virtually dry machining process that comes from applying minimal quantity lubrication technology means that laborious cleaning and drying of the machine and workpieces is virtually eliminated. Innovative and proven technology for health and the environment Issues such as ecology, energy saving and protection of the environment, as well as occupational health and safety, are of increasing importance. Given that the ecological benets of the MQL is astonishing, bielomatik has set itself high goals and standards...

Minimal quantity lubrication technology has become a proven manufacturing solution MQL is an Innovative technology that has evolved and come into its own During the mid 1990s solutions to dry machining and minimal quantity lubrication were systematically developed. bielomatik was an early participant in the relevant research projects and forms part of the avant-garde in minimal quantity lubrication technology. In the last ten years, MQL systems have proven themselves at bielomatik and in the market place due to their, in many respects, outstanding process in the cutting or mechanical...

The complete minimal quantity lubrication technology bielomatik offers both MQL 1-channel and MQL 2-channel systems. We know the benets and application perameters of both systems and can therefore offer the best solution to meet customer requirements. bielomatik MQL 1-channel system In the MQL 1-channel system an aerosol is produced thanks to the patented bielomatik multiple nozzle technology. This is fed to the tool via the aerosol line, rotary union and the spindle or the turret. The use of the bielomatik MQL 1-channel system is in cutting processes with low to medium spindle speeds It...
