Precision Aluminum CNC Milled Parts

Honmor Precision Aluminum CNC Milled Parts made in China are those high-precision aluminum parts processed by CNC milling technology, which is a kind of process where rotating cutting tools remove material from aluminum workpieces to form a complex 3D shapes, holes, grooves, or multi-face structures. Different from turned parts(focus on rotational geometries), milled parts are excellent in processing irregular or flat-featured components, such as laptop’s cases, automotive battery trap and industrial equipment brackets. Honmor adapts high-grade aluminum alloy and advanced 3-axis/5-axis CNC lathes to produce aluminum milled parts. These equipment feature high-speed spindles and precision linear guides which can achieve tight tolerance of ±0.02mm and surface roughness Ra0.8 and surface treatment like anodizing, sandblasting, or laser engraving can be offered to meet functional and aesthetic demand simultaneously. Therefore, whether you want to customize small-batch of precision milled aluminum parts for prototype development or purchase large-batch of components for mass production, Honmor is able to provide customized solution which can balance precision, cost, and delivery time, simplifying the procurement process of milled aluminum parts.

Core Advantages

Lightweight design for weight-sensitive applications

With feature of low density(1/3 that of steel), aluminum milled parts are ideal for industries where weight reduction is important(such as new energy vehicles and portable electronics). For example, Hommor’s AW 6061-T6 milled parts, which offer a tensile strength of 310Mpa, meeting the structural need while reducing component weight by 60% compared to steel equivalents. A Chinese new energy vehicle (NEV) manufacturer sourced 6061-T6 aluminum battery trays from Honmor: these Precision Aluminum CNC Milled Parts weighed 8kg, 5kg lighter than steel trays, improving the vehicle’s battery range by 12km. When customers are to purchase components for weight-sensitive applications from Honmor, the engineers will provide the best recommendations of alloy grade and optimize geometry to further reduce weight without compromising rigidity.

Multi-face processing for complex shapes

CNC milling technology is able to process multiple face in one setup, eliminating repeated clamping errors, especially suitable for complex aluminum CNC milled parts. Honmor’s 5-axis CNC milling machines (DMG MORI CMX 600V) can tilt the workpiece at any angle (0-360°), allowing cutting tools to reach hidden features (e.g., inclined holes, curved grooves) that 3-axis machines cannot. For example, a consumer electronics client needed a 7075-T6 aluminum laptop top cover with 12 inclined ventilation holes (30° angle) and a ribbed internal structure: Honmor’s 5-axis milled parts completed all features in 20 minutes per piece, compared to 45 minutes with 3-axis machining (which required 2 clamping steps). This efficient feature shorten production cycles by 40% for complex parts, which help customers meet tight market launch deadline when they are in large needs.

Customized surface treatment for divers needs

Honmor provide customized surface treatment for Precision Aluminum CNC Milled Parts to enhance function and aesthetics. For outdoor equipment, anodizing(Type II/III) generate a wear-resistant oxide layer that will enhance corrosion resistance a lot. Sandblasting gives parts a matte finish, hiding minor scratches and matching consumer electronics’ design language (e.g., smart speaker casings). Laser engraving can add logos or serial number to achieve traceability of products. A European smart home manufacturer customized 5052-H32 sensor housings made of aluminum from Honmor, these aluminum CNC milled parts underwent Type II anodizing (black) and laser engraving, the layer produced by anodizing passed 500-hour salt spray test and the engraving content remain clear after 10,000 touches. This customization ability helps clients differentiate their products in competitive markets.

Application Fields

Automotive and new energy vehicles

Aluminum CNC milled parts are widely used in automotive system to reduce weight and improve fuel efficiency. Main applications covering new energy battery trays, motor housings and chassis brackets. Honmor provide 6061-T6 aluminum alloy battery trays for Chinese leading new energy vehicles brand, these aluminum CNC milled parts possess features of flatness tolerance of ±0.03mm to ensure tight sealing between battery packs, and its anodized surface enable to defend electrolyte corrosion. Tests indicate that the trays still maintain structural completion after driving over 100,000 km, meeting the requirement of vehicle’s 8-year warranty. For motor housings, Honmor’s 7075-T6 milled parts with dimensional accuracy of ±0.02mm, which ensure the motor rotor rotates smoothly with minimal friction.

Consumer electronics and smart device

In the field of consumer electronics, aluminum CNC milled parts are helpful for slim, lightweight product designs. Typical applications include laptop chassis, smartphone middle frame and smartwatch cases. A South Korean consumer electronics giant procured laptop chassis made of aluminum alloy 7075-T6 from Honmor, these parts with thickness only 2.5mm and 300g weight, contributing to the laptop’s 1.2kg ultra-light design. With surface roughness Ra0.8, the chassis have a smooth touch feeling, while its tensile strength of 572Mpa support 1.5m drop test without deformation. For smartwatch cases, Honmor use 5052-H32 milled parts with sandblasted anodizing to ensure scratches from daily use.

Industrial equipment and automation

Industrial devices relies on precision aluminum CNC milled parts for structural stability and precision. Common applications include automation robot arms, testing instrument bases and hydraulic valve blocks. Honmor manufactures 6061-T6 aluminum robot arms for a German automotive company these aluminum CNC milled parts possess a straightness tolerance of ±0.02mm over 500mm length which ensures the robot’s end effector moves to the correct position with 0.01mm accuracy. The robot arms adapt lightweight design which reduce motor load efficiently and extend the lifespan by 20%. For testing tool bases, Honmor’s 7075-T6 milled parts with flatness less than 0.01mm provide stable platform for precision measurements.

Procurement and Customization Process

Demand Communication & Design Optimization

Customers share their requirements about Swiss Type Parts including 2D/3D drawings(CAD, SSTEP and IGS are supported), alloy grade preference, tolerance grade, surface treatment and quantity. Honmor’s engineers will inspect them to evaluate machinability. If there is any better option in surface treatment, diameter or material grade, our engineers will provide the best solutions for long-term use.

Quotation & Contract Signing

Honmor will issue detailed quotation within 12 hours including alloy material cost, machining fee(based on part complexity), surface treatment cost and certification fee(such as ISO 9001, aerospace AS9100). After confirming, the formal contract is to be signed, which covers quality standards, delivery time and payment conditions. For regular customers, Honmor provides volume discounts.

Sample Production & Quality Inspection

For customized precision aluminum CNC milled parts, Honmor adapts specified alloy and equipment to produce 2-3 pieces of samples. All samples must pass three inspections:1, dimensional test(via CMM with ±0.01mm precision to verify tolerance, concentricity, and straightness); 2, surface quality test(visual inspection for surface scratches); 3, Material verification(via spectroscopic analysis to confirm alloy grade). After completing these inspection, Honmor will send detailed test reports to customers for reference. If there is any adjustments needed, Honmor conducts remake promptly until meet all requirements.

Bulk Production & Global Delivery

After the samples approval, Honmor starts mass production by using automated CNC lathe with bar feeders which ensures consistency of precision and efficiency. During production, member of quality control department will inspect parts randomly every 2 hours, 5% of each batch will be inspected tolerance and surface treatment and any non-conforming parts are reworked and discarded. After production, all the final parts are cleaned with ultrasonic cleaners and packed in anti-scratch foam, for small parts, they are to be sealed in moisture-proof bags to avoid oxidation. With long-term collaboration with DHL and FedEx, Honmor is able to deliver the goods to global automotive factories, ensuring delivery as agreed in the order on time and provides logistic number allowing customers to monitor delivery progress in real time.
