Engine Block

Product Name: Engine Block

Material: Ductile Iron

Dimensions: 750 × 720 × 780 mm

Processing Method: 5-Axis CNC Machining

Product Features:

As a core component of marine power systems, this product involves machining oversized irregular structural parts. For key features such as complex internal flow channels, high-precision cylinder liner mounting surfaces, and crankshaft bearing bore systems, our 5-axis simultaneous machining technology enables multi-angle dynamic milling. The entire process—including curved surfaces, angled holes, and thin-walled structures—is completed in a single setup, achieving tolerances of ±0.01 mm and surface roughness of Ra 0.1 μm.

By leveraging our proprietary toolpath optimization and thermal deformation compensation system, we overcome challenges related to machining stress relief in cast iron. Integrated in-process inspection ensures 100% full inspection of critical mating surfaces, delivering zero-defect, high-strength precision engine blocks for marine applications. This exemplifies our technical leadership in machining complex heavy industrial components.
