Liechti Engineering Improves Accuracy and Efficiency with Automated Adaptive Milling Technology and Minimal-quantity Lubrication Process
Lincolnshire, Ill., September 13, 2019 – To help aerospace manufacturers keep pace with the ever-increasing demand for flawless components, Liechti Engineering, a GF Machining Solutions brand and worldwide leader in 5-axis airfoil machining solutions for aerospace and power generation turbine manufacturing, has automated the adaptive milling process to improve efficiency and eliminate human error. At the same time, newly benchmarked customer data demonstrates the effectiveness of its unique minimal-quantity lubrication process.
Automated Adaptive Milling
While adaptive blade milling itself is not new, Liechti’s approach to automation changes the way high-value aerospace components are manufactured. With automated adaptive blade milling, the workpiece is measured in the machine and the TURBOSOFT computer-aided manufacturing (CAM) software generates and optimizes the tool path, which, by eliminating human error, optimizes productivity and ensures the highest quality result.
Adding to its efficiency and reflective of a significant step forward for blade manufacturers, Liechti Engineering’s automated adaptive blade milling solution can be fully integrated with a range of flexible manufacturing systems (FMS).
Minimal-quantity Lubrication Process (MQL)
Newly benchmarked data proves out the benefits of Liechti’s unique MQL process, which places a small amount of lubricant exactly where it is needed through the spindle on the cutting tool to eliminate any loss of efficiency. In collaboration with Blaser Swisslube, an international developer and producer of high-quality metalworking fluids, and Switzerland-based machining specialist Walter AG, Liechti demonstrated that its MQL concept optimizes the milling of steel turbine blades and elevates machining beyond conventional standards.
The benchmarking study included several test scenarios in multiple environments. The Blaser Swisslube portion of the MQL study demonstrated both reduced flank wear and excellent surface finishes in the machining of X20 chrome steel blocks. Additional testing at Liechti Engineering in Langnau, Switzerland used a Liechti Turbomill 1400i to process difficult-to-machine X20. The use of the MQL process reduced cutting edge wear and tool life was extended. In fact, tests showed that polishing with MQL can reduce tool wear by up to five times compared to standard metalworking fluid.
Where alternative cooling methods fall short, MQL offers additional flexibility. With both metalworking fluid and MQL at their disposal, blade manufacturers are equipped with the ideal process for any application that comes their way.
MQL is available on all new Liechti machine models and can be retrofitted on legacy models currently in the field.
