Machining of Crankshafts and Camshafts

Iran Tractor Forging Company: A Leader in Machined Crankshaft and Camshaft Production

:Crankshaft
The crankshaft is the heart of an internal combustion engine and a strategic component in the power transmission system. Continuously subjected to torsional and bending stresses, the crankshaft requires high strength, fatigue resistance, wear resistance, and low thermal expansion. Therefore, the raw material for crankshafts must be medium-carbon steel or alloy steel containing chromium and nickel. The manufacturing process significantly impacts the component's physical and mechanical properties.
:Camshaft
The camshaft's function in an internal combustion engine is to open and close the intake and exhaust valves. Since bending and torsional loads are the primary causes of camshaft failure, manufactured camshafts feature a high surface hardness and a lower core hardness for increased toughness.

Iran Tractor Forging Company A Leader in Crankshaft and Camshaft Production
Leveraging decades of experience and the expertise of skilled domestic engineers, Iran Tractor Forging Company produces forged crankshafts for light and heavy-duty vehicles, as well as agricultural machinery, meeting international standards. The table below presents the technical part numbers and weights of the forged components produced by Iran Tractor Forging Company.
Following the forging process, crankshaft and camshaft components undergo several intricate and precise machining operations using CNC lathes and milling machines. Due to the complexity and tight tolerances involved, the machining process for crankshafts and camshafts requires high precision and advanced control tools. After machining and quality assurance, the components undergo heat treatment to enhance fatigue resistance. Finally, crack detection, balancing, and fatigue tests are conducted on all components before delivery to the customer.
Iran Tractor Forging Company plans to expand its machining lines for crankshafts and camshafts in future projects, enabling the company to machine a wider range of crankshafts and camshafts and offer finished, ready-to-use components to domestic and international markets.
