Crankshaft

Since the 1980s, China has gradually introduced CNC milling technology in the crankshaft processing field. Initially, three processes were mainly used: CNC turning, CNC internal milling, and CNC turn-broaching to process main journals and connecting rod journals. With the iterative upgrading of machine tools and cutting tools, crankshaft high-speed external milling process emerged and quickly […]

As a core component of automotive powertrain systems, engine performance directly affects overall vehicle operating quality. The crankshaft, as a key transmission component, has dimensional accuracy and surface machining quality of its journals that not only relate to crankshaft operating smoothness but also directly affect component wear rates and noise control levels. The crankshaft center

As a core component of automotive engines, the crankshaft plays a key role in converting the reciprocating motion of pistons into rotational motion. To reduce friction loss between connecting rods and journals and extend component life, oil passageways are designed on main journals to import and export engine oil for effective lubrication. However, deep hole

IATF 16949, as the authoritative quality management standard in the automotive industry, serves the entire lifecycle of automotive-related components from design, production to assembly. Based on the core framework of this standard and combined with crankshaft processing characteristics, this article systematically elaborates on a complete IATF 16949 compliant crankshaft automated production line solution, covering process
