REALISING HIGH SPEEDS IN HIGHLY DYNAMIC PROCESSES MINIMAL QUANTITY LUBRICATION (MQL) SYSTEMS IN METAL CUTTING CHARAKTERISTICS → Separate feeding of oil and air through spindle via rotating lance → Oil and air are transported together close to the process at the tool cutting surface FEATURES → Oil feed can be calibrated (independently of speed) → Maximum oil quantity independent from airflow of feeding channel of tool → Very quick reaction (0.1 sec.), oil quantity change at tool center point immediately active → MQL oils with higher viscosity up to max. 100 mm²/s → Applications from 4 bar up to 10 bar of compressed air Dry chips, dry parts, dry machine Higher cutting speeds, reduced processing times Better surface qualities due to pure lubricant Longer tool life (no thermal shock stress) Reduced invest cost for new machines SUSTAINABILITY ASPECT (compared to coolant): → approx. 50% less CO2 –Emission → up to 90% less water consumption → up to 98% less hazardous waste Nmax approx. 40.000 rpm spindle speed Machine centers (frequent tool change) Machine tools at high production rates Tools with “high” oil consumption Demanding cutting processes such as deep hole drilling or thread cutting → Set oil quantity can be checked MQL 1-channel and 2-channel systems, Mobile Lubrication Unit for aerospace industry bielomatik Leuze GmbH + Co.
