Precision Heavy Machining for Critical Industrial Applications

In the demanding landscape of heavy industry, power generation, and marine propulsion, structural integrity relies entirely on the precision of rotational components. At Akyavuz Endüstri, located in the industrial heartland of Kocaeli / Kartepe in the Marmara Region, we specialize in the advanced contract manufacturing of large diameter heavy flanges, adapter rings, and torque transmission hubs. Engineered to withstand extreme mechanical loads and high rotational forces, our components serve as the backbone for heavy machinery, wind turbines, mining equipment, and industrial processing plants worldwide.

Advanced Manufacturing Infrastructure in Kocaeli

Producing heavy-section components with diameters reaching up to 4 meters requires uncompromising manufacturing capabilities. Our state-of-the-art facility near Istanbul integrates heavy fabrication with high-precision machining technologies. We utilize advanced 4-meter vertical lathe turning centers to achieve exceptional concentricity and surface finish on massive forged steel rings. Following rough machining, our workpieces undergo controlled stress relieving thermal treatments to eliminate residual internal stresses, guaranteeing long-term dimensional stability during high-speed operations.

To ensure absolute precision, secondary operations are executed on heavy-duty CNC horizontal boring machines and high-accuracy gantry milling centers. This allows us to deliver:

  • Tight tolerances down to micron levels on critical bearing fits and pilot diameters.
  • Complex bolt hole patterns, keyways, and internal splines machined to exact OEM specifications.
  • Rigorous quality assurance backed by certified CMM inspection and non-destructive testing (NDT).
  • Custom metallurgical sourcing, utilizing high-grade forged steel heavy flanges and alloy steels tailored to specific environmental and thermal demands.

Strategic Nearshoring and Logistics from Turkey

Global supply chain volatility has made reliable nearshoring a strategic imperative for European and North American OEMs. Sourcing heavy contract manufacturing from Turkey and the Marmara Region offers unmatched logistical and economic advantages. Situated at the crossroads of Europe and Asia, our facility in Kocaeli provides rapid, cost-effective overland and maritime freight connections to European markets, drastically cutting lead times compared to Asian alternatives.

At Akyavuz Endüstri, we combine Turkish engineering ingenuity with stringent international quality standards, including ISO and military-grade compliance. This ensures that international supply chain directors receive European-tier quality at highly competitive production costs.
