Replacing traditional flood coolant systems, Microlube features an ‘applicator’ unit and pneumatic control to deliver very small amounts of a vegetable-based oil that has no EP additives or chlorine. The lubricant is pumped through a small capillary tube around which an outer tube blows compressed air to effectively ‘splat’ it onto the cutting tool – unlike a spray mist system which atomises much smaller particles of fluid.
Traditional flood coolants are generally 5 - 10% soluble oil mixed with water, and work by dissipating the heat with the sheer volume of liquid passing the cutting area. AML have found that by applying a thin film of neat vegetable oil to the cutting edge, the friction generated in the cut is significantly reduced, as is the heat and tool wear. Other clear benefits include better surface finish, dry swarf, cleaner working conditions and NO disposal costs.
