Engineering Excellence in Heavy Power Transmission Components

In the realm of heavy industrial machinery, mining equipment, marine propulsion, and large-scale wind turbines, the reliability of power transmission systems is non-negotiable. At the heart of these systems lie complex structural and rotating components: heavy gearbox casings, robust planetary carriers, and high-strength heavy pinion shafts. At Akyavuz Endüstri, located in Kocaeli / Kartepe in the industrial heartland of Turkey’s Marmara Region, we specialize in delivering precision contract manufacturing for these demanding applications.

Designing and machining these components requires a rare fusion of large-scale fabrication prowess and micrometric mechanical precision. A failure in structural alignment or gear mesh can lead to catastrophic downtime. Therefore, partnering with an experienced OEM manufacturer equipped with state-of-the-art infrastructure is critical for international supply chain directors and mechanical engineers.

Technical Capabilities: From Weldment to CMM Inspection

Manufacturing large gearbox housings and torque transmission couplings involves a rigorous, multi-stage engineering workflow. Our plant utilizes advanced CNC horizontal boring machines and massive gantry milling centers capable of handling oversized castings and heavy weldments with exceptional dimensional stability.

Core Manufacturing Processes

  • Large Frame Fabrication & Structural Weldments: Utilizing certified welding procedures to construct rigid structural housings capable of withstanding extreme operational loads and vibration.
  • Thermal Stress Relieving: Controlled thermal treatment cycles to eliminate residual stresses from welding and rough machining, ensuring long-term geometric integrity.
  • Precision CNC Horizontal Boring & Milling: Achieving tight geometrical tolerances down to microns for bearing journals, bore alignments, and mating faces.
  • Heavy Turning & Spline Milling: Manufacturing long-span heavy pinion shafts and high-torque shafts from alloy steel forgings with superior surface finishes.
  • Advanced Metrology: Comprehensive dimensional verification utilizing large-envelope CMM inspection systems to guarantee compliance with rigorous international standards.
