Technology ‘Near dry’ machining cools things down, including costs
The Micro Lube minimal quantity lubrication system from Advanced Carbide Tooling Ltd uses a plant-based oil and offers both reduced machining costs and improved processing results, according to its supplier.
The Micro Lube system from ACT subsidiary Advanced Micro Lubrication is said to provide “near dry'” machining advantages without the downsides of flood coolants. As a flood coolant replacement system, Micro Lube 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 spray the oil onto the cutting tool.
Stand-alone unit can be used on different machines
The Micro Lube device is a small stand-alone unit that can be set up easily beside or behind a machine tool, the company said. ACT also noted that its compact sized device can be transferred from one machine to another and configured to meet specific customer demands for sawing, milling, drilling, tapping and reaming, swaging and pipe manipulation. Moreover, varying the length of the stroke of the pump enables the system to control the volume of liquid, while a small frequency generator controls the timing of each pulse.
