Product Advantages
Lightweight Material Design
A titanium alloy with a density of 4.5g/cm³ replaces conventional steel. Hot isostatic pressing achieves both structural strength and weight reduction, making it suitable for marine propulsion systems and critical support structures.
High-Precision Five-Axis Machining
Utilizing a five-axis CNC milling center and a high-precision servo control system, combined with ±0.002-inch toolpath control, reduces secondary clamping errors and improves assembly consistency.
Corrosion-Resistant Surface Treatment
Passivation treatment removes free iron ions, followed by a 60μm-thick epoxy anti-corrosion coating. Neutral salt spray testing ensures stable operation for over 720 hours in saltwater environments.
Comprehensive Defect Inspection
Internal quality is scanned using a 10MHz ultrasonic probe, and dimensional accuracy is controlled within ±2μm by a coordinate measuring machine. This covers key internal and external indicators, ensuring that each batch meets the structural integrity requirements for use in maritime equipment.
Quality Assurance
- Stringent quality checks in each production process. Ultrasonic testing and magnet particle testing to inspect internal faults or cracks in the part is carried out to determine internal faults or cracks in the part.
- Dimensional verification is achieved by accurate measurement tools like coordinate measuring machines (CMMs) to check that the parts have measurements required in shipping applications.
Customization
- Marine CNC machining items generally have to be bespoke to fit exact equipment and boat design specifications. Manufacturers work in tandem with boat design professionals and marine engineers to decide requirements and design to about parts to integrate in with system overall. Whether an exotic valve part or specialist bracket is required, bespoke is part of production by default.
FAQ
Q: Are CNC Milling Parts for Marines suitable for long-term seawater environments?
A: They are suitable for long-term high-salt, humid environments. The surface is passivated and coated with an anti-corrosion coating to effectively resist corrosion and extend service life.
Q: What custom requirements can be met for these parts?
A: We support customization of non-standard structures, special hole positions, and interface dimensions. We can process according to drawings or 3D models to adapt to different marine systems.
Q: Do complex parts require multiple setups?
A: Using five-axis integrated machining equipment, we can produce complex geometries without multiple setups, improving machining accuracy and consistency.
Q: How do we ensure internal defect-free parts?
A: Every part undergoes ultrasonic or magnetic particle inspection to identify internal defects such as cracks and pores to ensure structural integrity.
Q: Are surface treatment options available?
A: You can choose from passivation, anodizing, or epoxy coating to meet different performance requirements for corrosion resistance and wear resistance.
