High-Precision Aluminium CNC Machined Components for Industrial Use

2011-T3 is the classic free-machining grade for high-volume turned parts; 6262-T6 and 6026 are lead-free free-machining alternatives with better corrosion resistance; 6061-T6 and 6082-T6 are used where anodizing and weldability matter; and 7075-T6 or 2024 are chosen for high-strength fittings.

Yes. Leaded aluminium grades are only used within permitted exemptions, and for lead-free requirements we machine 6026, 6262 or 6061/6082. Material certificates confirm chemistry so you can document compliance with ELV, RoHS and REACH.

Turned diameters are routinely held to ±0.01–0.02 mm, with runout and concentricity typically within 0.02 mm on parts turned in a single setup. Lengths and shoulders are usually held to ±0.05 mm, and tighter values can be achieved on critical features after drawing review.

Automotive turned parts are produced on CNC turning centres and auto lathes with bar feeders, live tooling and parts catchers, allowing turning, drilling, cross-drilling, tapping, knurling and milling of flats in one cycle for consistent, high-volume output.

Both. Cut threads are used for most internal and small-batch external threads, while roll-formed external threads give higher fatigue strength and a smoother flank finish on high-volume fasteners and fittings. Threads are made to ISO metric 6g/6H, UNF/UNC 2A/2B or 3A/3B and inspected with ring and plug gauges.

Yes. O-ring grooves are machined to ISO 3601 or AS568 dimensions with controlled groove finish (typically Ra 0.8–1.6 µm), and sealing cones, flare seats and face seals are turned to the finish and angle specified by the relevant SAE, ISO or DIN fitting standard.

Clear, black and colour anodizing for corrosion protection and identification, hard anodizing for wear-resistant parts, trivalent chromate conversion for conductivity and paint adhesion, and electroless nickel for sliding or sealing surfaces. Masking is available for threads and grounding points.

We use first-off approval, in-process gauging at defined intervals, tool-life management and statistical process control on critical dimensions. Capability studies (Cp/Cpk) can be provided for key characteristics, and every lot is traceable to its raw-material heat number.

Cross-drilled and threaded holes are deburred mechanically and, where required, by tumbling or vibratory finishing. Parts are washed in solvent-free cleaners and dried to prevent chips or oil residue from entering hydraulic, brake or fuel systems.

From 10-piece prototypes to production batches in the hundreds of thousands. Once a part is running, we can agree blanket orders with scheduled call-offs and safety stock to support just-in-time deliveries to your assembly line.

Small parts are bagged by count, while cosmetic or precision parts are packed in separated trays or layered cartons to prevent dents and scratches. VCI protection is used for export, and each carton is labelled with part number, quantity, lot number and PO reference.

Often, yes. Aluminium offers about one-third the weight of steel and good corrosion resistance when anodized. It suits low- to medium-pressure hydraulic, pneumatic, fuel and coolant fittings, but pressure rating, thread wear and galvanic compatibility must be reviewed. Our engineers can advise on each application.

Yes. First-article inspection reports are provided for new parts, and PPAP-style packages (dimensional results, material certificates, process flow and control plan) are available on request for automotive programs.
