Precision OEM Aluminium Components Cnc Turning Service

Surface Finishing and Precision Tolerance Services for High-Quality Metal Fabrication

Our advanced surface finishing and dimensional accuracy solutions deliver exceptional quality for both standard and high-precision metal components. Whether you're manufacturing parts for automotive, aerospace, medical devices, or industrial machinery, our expertise in CNC Milling, turning, and post-processing ensures that every product meets rigorous engineering standards while maintaining aesthetic appeal and functional integrity.

Key Features:

• Customizable Surface Roughness Control – From basic machining finishes to mirror-like polish, we tailor surface texture using precise toolpath programming and optimized cutting parameters, suitable for assembly compatibility or ultra-smooth applications.
• Specialized Surface Treatments – Enhance durability with heat treatment, electroplating, chemical coating, or laser hardening; ideal for corrosion-resistant or wear-prone environments.
• Functional Texturing via Knurling & Engraving – Add grip, branding, or ergonomic design elements through controlled surface patterns without compromising structural performance.
• Ultra-Fine Dimensional Tolerances – Achieve ±0.01mm accuracy for general components and up to ±0.001mm for critical precision parts—ensuring perfect fit and long-term reliability.
• Form and Position Accuracy – Strict control over roundness, concentricity, flatness, parallelism, and perpendicularity guarantees optimal part interaction and system-level functionality.

Detailed Description:

At the core of our manufacturing process lies a commitment to excellence in both surface finish and geometric precision. Using state-of-the-art CNC machines equipped with adaptive feed and speed controls, we produce consistent results across various materials—including stainless steel, aluminum alloys, titanium, and hardened steels. For surfaces requiring enhanced aesthetics or performance, we integrate secondary operations such as grinding, polishing, or micro-abrasive blasting to achieve Ra values ranging from 0.8 µm to 0.1 µm. These methods not only improve appearance but also reduce friction, increase fatigue resistance, and enhance wear life.

In addition to mechanical precision, we focus on form tolerance management—ensuring that each component maintains its intended shape and spatial relationship within tight margins. This is particularly vital in assemblies where misalignment could lead to premature failure or reduced efficiency. Our metrology team employs coordinate measuring machines (CMMs) and optical comparators to verify all critical dimensions and geometrical specifications before final delivery.

Applications Across Industries:

These capabilities make our services indispensable for industries demanding high-reliability components. In the automotive sector, engine blocks, transmission housings, and sensor mounts benefit from precise tolerances and durable surface treatments. Aerospace manufacturers rely on us for turbine blades, landing gear components, and avionics enclosures that must withstand extreme conditions. Medical device makers use our services for surgical instruments, implants, and diagnostic equipment where biocompatibility, cleanliness, and micron-level accuracy are non-negotiable.

User Testimonials:
