MINIMUM QUANTITY LUBRICATION (MQL) REDUCES THE AMOUNT OF COOLANT USED

TENDO Hydraulic Toolholders from SCHUNK can be modified for MQL applications. MQL is a metering technique that reduces the amount of coolant used to a minimum. The coolant is injected or sprayed into the working area between the tool and the workpiece. The internal design of the toolholder components resembles a spray nozzle system. The coolant-air mixture is sprayed into the contact area of the cutting tool reducing friction and temperature. This evaporative process along with the flow of compressed air provides additional cooling of the tool.

Use of the MQL system results in a virtually coolant-free process. In perfectly adjusted systems, swarf, workpiece and tools remain almost completely dry. MQL can be used in applications where friction needs to be reduced through the application of coolant. This process is ideal for drilling, deep hole drilling, milling, threading and turning.
