This high-precision aluminum component is manufactured using advanced CNC processing technology, combining milling and turning processes, to ensure that each part meets industrial-grade standards in terms of size and surface quality. The overall design has undergone strict process optimization, which not only guarantees structural strength but also enhances appearance and assembly accuracy, making it highly suitable for applications in automated equipment, mechanical modules, and precision instruments.

Material and Process Advantages
The parts are made of high-quality aluminum. They undergo multiple processing steps to achieve precise shaping. The processing procedure includes milling → turning → secondary milling → black oxidation treatment. Each step strictly controls the tolerance within ±0.01 millimeters to ensure a high degree of matching between the parts and the assembly components, thereby reducing error accumulation. The black oxidation treatment on the surface not only enhances wear resistance and corrosion resistance but also gives the parts a professional and high-end appearance, suitable for various industrial environments.
Precise design and application compatibility
The part's geometric structure is compact, and the hole positions and grooves are precisely designed, facilitating direct matching with various mechanical components. Whether used in automated machinery, instruments and meters, or in the prototyping of high-end equipment, it can provide stable mechanical performance. The multi-functional design enables flexible application in various assembly methods, while the surface treatment enhances friction performance and service life.
Small-batch customization and rapid delivery
This product supports a minimum order quantity of 1 unit, which greatly meets the needs of small-batch customization or prototype testing. The delivery cycle is only 5-25 days. Combined with the high efficiency of CNC processing, it can quickly respond to the design iteration requirements of customers and help the product be put into production quickly.
Quality Assurance and Customer Experience
Every component undergoes rigorous quality inspection before leaving the factory, including size measurement, surface smoothness testing, and oxide film thickness measurement, to ensure that the final delivered components fully meet customer requirements. High-precision processing combined with professional surface treatment not only enhances the performance of the components but also enables customers to experience greater reliability and stability during assembly and use.
Applicable Industries and Scenarios
This CNC aluminum part is widely applicable in fields such as precision machinery, industrial automation, electronic equipment, instrument and metering devices, and prototype development. Whether for developing prototypes, conducting experimental verification, or small-scale production, it can provide high-precision and high-strength solutions.
Through precise milling and turning processing techniques, strict tolerance control, and durable black oxide surface treatment, this aluminum part not only has reliable performance, but also combines beauty and industrial practicality. It is an ideal choice for overseas buyers who pursue high quality and efficiency.
