Product catalog summary
Introduction to Minimal Quantity Lubrication (MQL) Systems in Metal Cutting
Minimal Quantity Lubrication (MQL) systems provide an efficient and environmentally friendly alternative to traditional coolant emulsion (CE) systems in metal cutting. This document discusses the requirements, challenges, and benefits of MQL systems compared to conventional methods.
Challenges with Coolant Emulsion (CE)
  • CE systems require complex infrastructure, including pumps, reservoirs, and piping, along with cleaning systems for workpieces and swarf.
  • Disposal of CE involves high costs and environmental risks if not managed properly.
  • CE systems need biocides to prevent microbial degradation, posing environmental hazards.
  • Water-mixed CE emulsions have limited service lives, requiring frequent replacement and cleaning.
  • Health risks include skin disorders, respiratory issues, and allergies due to exposure to CE.
  • Strict legal regulations are in place to protect workers from hazardous substances.
Advantages of Minimal Quantity Lubrication (MQL)
  • MQL reduces coolant emulsion consumption, enhancing productivity and sustainability.
  • Involves precise oil metering directly to the tool, with heat dissipation via swarf.
  • Requires minimal power for oil transport, resulting in oil-free workpieces and recyclable swarf.
  • Reduces energy consumption and CO2 emissions compared to CE.
  • Allows higher machining speeds, shorter cycle times, and up to 15% increased productivity.
  • Tools maintain even temperatures, leading to longer service life.
MQL System Types and Features
  • MQL 1-channel system: Suitable for low to medium spindle speeds, easy to install and operate, supports up to 16,000 rpm.
  • MQL 2-channel system: Ideal for high-speed processes, supports up to 40,000 rpm, suitable for high lubricant consumption tools.
  • External MQL system: Combines with the 2-channel system for tools without feeding channels, ensuring precise dosing.
Conclusion
MQL technology is a proven solution in manufacturing, offering health, environmental, and cost benefits. It is widely adopted in the automotive sector and supported by standards like DIN 69090. Bielomatik provides comprehensive MQL systems for efficient and sustainable metal cutting processes.

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 hazards...
