Case Study: Precision CNC Machining for Satellite Networks Antenna Component
Precision CNC Machining for Satellite Networks Antenna Component
Client Background
A leading satellite networks company reached out with a highly specialized requirement for one of their antenna components. The part in question was a custom aluminum sleeve, designed to house internal mechanisms of the antenna. It required extremely straight and precise grooves to be machined inside the cylindrical aluminum body – a critical feature to ensure signal accuracy and mechanical performance.
The Challenge
Traditional CNC machining methods struggled to meet the tight tolerances needed. The internal grooves had to maintain perfect alignment and depth throughout the sleeve’s length. any deviation would compromise the antenna’s performance. Early attempts using standard horizontal CNC setups failed to deliver the required accuracy and consistency.
Our Solution
After an in-depth analysis and test runs, we identified that the issue stemmed from the limits of horizontal machining for this geometry. Our engineering team proposed an unconventional yet highly effective solution: vertical CNC machining.
This allowed for:
- Superior groove alignment and straightness
- Improved chip evacuation and surface finish
- Greater part stability during the process
The switch not only solved the technical challenge but also resulted in a highly cost-effective production setup, with optimized tooling and a lower unit cost.
Results
- Precision: Internal grooves met all functional and dimensional specs
- Cost-Effective: Reduced tooling and per-unit cost
- Reliable Production: Stable process, ready for scaling
Client Outcome
The client was extremely satisfied. The new vertical CNC solution ensured flawless groove precision, enabling their antenna to meet both mechanical and performance standards, on budget and on time.
