Introduction:

CITEK Group is a major industrial force in Georgia, specializing in the production and maintenance of critical railway components. As a key player in the regional transportation sector, they demand absolute precision and reliability. We partnered with CITEK to deliver a specialized production line for train axles—a project that highlights our commitment to deep customization and technical excellence.

The Challenge: Meeting the Rigorous Standards of the Rail Industry

Manufacturing train axles is a high-stakes task. These components carry immense weight and must meet stringent safety standards. CITEK needed a solution to process axle ends and grind the main surfaces with extreme accuracy based on complex technical drawings. The challenge was to create a synchronized workflow where the initial centering and final grinding worked in perfect harmony to ensure the longevity and safety of the axles.

The Solution: A Synchronized, Custom-Built Production Cell

We developed a dedicated four-machine solution tailored specifically to CITEK’s requirements. First, we designed and delivered two custom CNC Milling & Centering Machines. These machines handle the precision facing and center-hole drilling of both axle ends, providing a perfect datum for all subsequent steps. Following this, we integrated two CNC Cylindrical Grinding Machines optimized for axle surface finishing. We engineered these grinders with reinforced beds and high-precision spindles to maintain micron-level tolerances across the entire length of the heavy axles.

The Result: Zero-Error Performance and Total Client Satisfaction

The success of the project was solidified during a rigorous one-month on-site acceptance period at our facility.

- The CITEK technical team meticulously tested every parameter of the machines, ensuring they met the exact specifications of their drawings.
- The equipment performed flawlessly, delivering consistent, high-precision results across hundreds of test cycles.
- The integration of automated milling and precision grinding significantly reduced their production time while enhancing the structural integrity of the finished axles.

By the end of the month, the CITEK team was highly satisfied, moving the machines into full production in Georgia with total confidence in our technology.

“The one-month acceptance process gave us complete confidence in this equipment. The precision of the cylindrical grinders and the specialized design of the milling machines are exactly what we needed for our axle production. We are impressed by the technical depth and the customized support provided by the team.”
