Engineering Solutions for Complex Parts
Reducing Material Deformation
For thin-wall and complex parts, we use dynamic cutting force compensation technology to adjust cutting parameters in real-time, reducing cutting force variation and minimizing material deformation. We also implement stress relief processes to eliminate residual stress.
Improving Tool Accessibility
With 5-axis technology, we can adjust the tool angle dynamically to reach hidden features and deep cavities that are impossible with 3-axis machines. This eliminates the need for EDM processes in many cases, reducing production time by up to 60%.
Optimizing Machining Sequence
Our engineers optimize the machining sequence to balance material removal and heat distribution, preventing thermal deformation. We also use adaptive roughing to remove material efficiently while maintaining stable cutting conditions.
Minimizing Setup Errors
One setup completes all machining operations, eliminating cumulative errors from multiple re-fixturing. We reduce setup times by 60% and improve overall accuracy, with positioning error controlled within 0.005mm*.
