Precision Crankshaft CNC Machining Services by EMAR

When it comes to crankshaft CNC Machining, precision and durability are non-negotiable. At EMAR, we specialize in delivering high-performance machined crankshafts tailored for automotive, marine, and industrial applications. Our advanced CNC technology ensures micron-level accuracy, meeting the strictest industry standards.

Why Choose CNC Machining for Crankshafts?

Traditional manufacturing methods often fall short in achieving the complex geometries and tight tolerances required for modern crankshafts. CNC machining eliminates these limitations through:

5-axis simultaneous milling for intricate counterweight profiles

Automated turning processes with live tooling capabilities

Consistent surface finishes below Ra .8μm

Material flexibility (alloy steels, forged steel, ductile iron)

EMAR's Crankshaft Manufacturing Process

Our CNC machining workflow combines German-engineered equipment with proprietary quality controls:

Material Certification: Traceable alloy verification

Rough Machining: Billet preparation with 30% excess material

Heat Treatment: Induction hardening for wear resistance

Finish Machining: ±.005mm journal diameter tolerance

Surface Enhancement: Shot peening for fatigue resistance

Industries We Serve

From high-rpm racing engines to heavy-duty diesel applications, our crankshafts deliver:

Automotive: Balanced designs for vibration reduction

Marine: Corrosion-resistant coatings

Power Generation: Oversized bearing surfaces

Aerospace: Lightweight titanium options

Quality Assurance Protocol
