Precision CNC Machined Parts

CNC Machined Precision Parts for Automation Systems

These are custom precision components for automation equipment, automotive systems and mechanical tools, machined on 3-, 4- and 5-axis CNC centers and lathes. Aluminum alloy, steel, brass, copper and titanium are used, and critical features reach down to ±0.005 mm. Parts are painted, powder coated, plated or polished. They suit OEMs and integrators needing consistent parts under ISO 9001 controls.

Manufacturing

How we make this part

Process, material options and inspection for cnc machined precision parts for automation systems.

Automation parts range from simple spacers to complex manifold blocks and actuator housings. We route each part to the right machine: lathes for round parts, 3-axis mills for plates, 4-axis for indexed features, and 5-axis for compound angles. Process sheets document setups, tools and inspection points, so repeat orders run identically. Assemblies can be kitted by station for installation.

Aluminum alloy dominates automation for weight and cost; steel and alloy steel are used for wear and load, brass for fittings, copper for conductive parts and titanium where light, strong, corrosion-proof parts are needed. Coatings protect and identify parts: painting and powder coating for frames, plating for steel, polishing for appearance. Heat treatment can be added to steel parts.

Our ISO 9001 system covers first-article inspection, in-process checks and 100% inspection of critical dimensions, using CMM, height gauges, thread gauges and roughness testers. Material certificates and inspection reports are available on request. Typical uses include robotic cell parts, conveyor components, automotive test fixtures, tool holders, gripper parts and machine guards.

FAQ

Frequently asked questions

Can you hold ±0.005 mm on every dimension?

No, and it is rarely necessary. Our standard tolerance is ±0.05 mm, and we hold down to ±0.005 mm on critical features where material and geometry allow. Apply tight tolerances only where function needs them, since they add machining and inspection cost.

Do you supply inspection reports with each order?

First-article reports are standard for new parts, and inspection reports for production batches can be supplied on request, along with material certificates. Tell us which dimensions or formats you need, and we will include them with shipments.

How do I get a quote for cnc machined precision parts for automation systems?

Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
