Precision Machined Automotive Camshafts

As a core transmission component of the internal combustion engine's valve train, this component controls valve opening and closing timing through specific profile curves. Its structure includes multiple eccentric cams, support journals, and end drive heads. The coaxiality and phase angle precision between shaft sections directly determine the smoothness and noise performance of the engine, requiring extremely high consistency in assembly benchmarks.

The manufacturing process focuses on controlling dimensional tolerances and surface roughness after outer cylindrical grinding to ensure wear resistance and oil film retention under high-speed rotation. For such parts, heat treatment processes such as quenching and tempering or carburizing are typically used to enhance core toughness and surface hardness. Meanwhile, CNC cam grinders are utilized to ensure the geometric precision of the lift curve, preventing valve motion interference caused by profile deviations.

Taizhou Dingzhen Camshaft holds IATF16949 quality management system certification and is equipped with CNC outer cylindrical grinders, inner cylindrical grinders, and specialized cam measuring instruments, enabling precise full-process manufacturing from blanks to finished products. We support material selection (such as 40Cr, 20CrMnTi) and customized heat treatment based on drawings, providing material reports and hardness test data. This meets the strict requirements for stable batch delivery in automotive parts and garden machinery powertrains.
