Tucson, AZ, Automotive Part Manufacturing: Real-World CNC Applications
Engine components and custom brackets are just a few examples of parts where CNC machining plays an essential role in automotive manufacturing. Roberson Machine Company collaborates with Tier 1–3 Suppliers, small businesses, and various partners to deliver precise, scalable parts for production. In the automotive industry, CNC machining is commonly used for:
- Powertrain Components: For parts like crankshafts, cylinder heads, and transmission housings, CNC machining delivers the extreme precision necessary for optimal performance, efficiency, and reliability, meeting the exacting tolerances these components require.
- Suspension & Steering Systems: Components like control arms, knuckles, and linkages must be lightweight, durable, and dimensionally consistent. Roberson’s machining expertise ensures each part supports proper handling and longevity.
- Brake System Parts: Caliper mounts, rotors, and pedal components require precise machining to ensure safety and consistent function. Proper surface finish, tolerance, and geometry are vital for optimal braking efficiency.
- Interior & Dashboard Hardware: CNC machining plays a vital role in creating not just mechanical parts, but also aesthetic and functional components like gear shifters, infotainment brackets, and dashboard support structures.
- Prototyping & R&D: Before full-scale production, many automakers rely on CNC-machined prototypes to test component fitness, performance, and safety. Roberson helps teams transition from CAD models to real-world parts swiftly, facilitating innovation and design validation.
- Electric Vehicle (EV) Components: With the rise of EV production, CNC machining plays a crucial role in crafting battery housings, cooling plates, and custom mounts for electric drive units, all demanding advanced design and material expertise.
- Autonomous Vehicle Systems: CNC-machined parts are vital for the functionality of sensors, control modules, and structural components in autonomous vehicles, playing a key role in the performance and safety of advanced driving systems.
- Performance & Aftermarket Parts: CNC machining enables the production of custom performance parts, such as intake manifolds, exhaust headers, and suspension upgrades, catering to enthusiasts seeking enhanced vehicle performance and aesthetics.
Roberson’s automotive manufacturing services are tailored to meet the industry’s demanding standards—whether you’re producing five parts or five thousand. Precision, consistency, and quality are our constant priorities.
Types of Materials We Use for Tucson, AZ, Automotive CNC Manufacturing
In the automotive industry, material selection is crucial for the performance, safety, and durability of vehicle parts. At Roberson Machine Company, we draw on a wide range of metals and plastics, each selected for its unique attributes—strength, weight, corrosion resistance, and machinability—to meet the specific needs of automotive applications. This includes:
- Aluminum (6061, 7075, 7050): Known for being both lightweight and resistant to corrosion, aluminum alloys are ideal for engine parts, suspension components, and housings. For high-performance uses, alloys like 7075 are the go-to choice, especially in motorsports.
- Stainless Steel (303, 304, 316, 321, 420SS, 416, 440): Stainless steels are prized for their strength and corrosion resistance, making them ideal for applications like exhaust systems, fasteners, and drivetrain components. For detailed insights on stainless steel, check out What Is Stainless Steel?. Hardened grades like 440 are especially known for excellent wear resistance.
- Plastics (Delrin, PETGs, Nylon, PLAs, PEEK, HDPE, Glass-Filled Nylon): Lightweight and durable, these plastics are perfect for non-structural components like bushings, gears, and interior parts. Some, like PEEK, offer excellent resistance to high temperatures and chemicals.
- Brass: Known for its excellent machinability and corrosion resistance, brass is commonly used for fittings, bushings, and valves in fluid-handling systems and connectors.
- Titanium: Lightweight and exceptionally strong, titanium is used in performance applications where strength-to-weight ratio is critical, such as exhaust parts and racing components.
