Role of Cutting Fluids in Micro-Milling

Cutting fluids play a critical role in micro-milling. They help reduce friction between the tool and workpiece, minimize heat accumulation, and efficiently remove chips, preventing debris from accumulating in the machining area. This improves machining quality and prolongs tool life.

Advantages of MQL Technology in Micro-Milling

MQL technology has emerged as a viable alternative to conventional cutting fluids, receiving increasing interest. MQL utilizes compressed air to inject a small quantity of cutting fluid into the machining area, providing both lubrication and cooling. This method reduces cutting fluid consumption, lowers lubrication costs, and shortens the cleaning time for workpieces, tools, and machinery. MQL also contributes to reduced processing costs, improved efficiency, and minimized environmental impact.

In micro-milling, MQL demonstrates significant advantages. Due to the smaller tool diameters and lower rigidity, micro-milling tools are prone to deformation under fluid pressure or cutting forces. Conventional cutting fluids struggle to remove microchips effectively, leading to heat buildup in the machining area, which affects precision and surface quality. MQL precisely controls the amount and location of the cutting fluid, reducing friction and heat, while enhancing tool life and surface integrity.

Application of Vegetable Oils and Nanofluids

Vegetable oils have emerged as an ideal alternative to mineral oils due to their biodegradability, low toxicity, and excellent lubrication properties. Though relatively more expensive, their environmental benefits and superior lubrication performance make them highly effective in micro-milling operations. Nanofluids, another cutting-edge technology, enhance the thermal and lubricating properties of cutting fluids by dispersing nanoparticles into the base fluid. In micro-milling, the use of nanofluid-enhanced vegetable oils significantly improves tool performance, reduces surface roughness, and lowers cutting forces.

Other Alternative Technologies

In addition to MQL and vegetable oils, dry machining, solid lubricants, and cryogenic cooling are also widely researched. While dry machining eliminates the use of cutting fluids, high friction and heat can shorten tool life. Cryogenic cooling utilizes liquid nitrogen or carbon dioxide to lower the machining temperature and improve surface quality, but it is associated with high equipment costs. Solid lubricants provide excellent lubrication under extreme conditions, helping to extend tool life.

Moving forward, the field of micro-milling requires further research to develop new cutting strategies, optimize cutting fluid delivery methods, and evaluate various performance indicators. The application of new environmentally friendly cooling and lubrication technologies will contribute to more sustainable machining processes. Researchers should aim to explore more efficient and eco-friendly lubrication techniques to address the challenges faced in micro-milling operations.

Sustainable Cutting Oils and the Future of Micro-Milling

In summary, the application of cutting fluids and MQL technology in micro-milling holds vast potential. By adopting advanced lubrication and cooling techniques, machining quality and efficiency can be improved, while environmental impact is reduced, enabling sustainable development. As technology continues to advance, micro-milling operations are expected to see more innovations and breakthroughs.
