Lexington, KY, Automotive Part Manufacturing: Real-World CNC Applications
From engine parts to custom brackets, CNC machining is essential in the automotive manufacturing process. Roberson Machine Company collaborates with Tier 1–3 Suppliers, small businesses, and other partners to produce precise, production-ready components at scale. Common automotive applications include:
- Powertrain Components: Crankshafts, cylinder heads, and transmission housings are integral to vehicle performance, requiring high-precision machining to maintain efficiency and reliability. CNC machining ensures the tight tolerances these critical components need for maximum performance.
- Suspension & Steering Systems: Components like control arms, knuckles, and linkages require a precise balance of weight, strength, and dimensional accuracy. Roberson’s machining capabilities ensure each part performs reliably and withstands the test of time.
- Brake System Parts: Caliper mounts, rotors, and pedal components are machined for safety and smooth function. Surface finish, tolerance, and geometry are critical to ensure effective braking performance.
- Interior & Dashboard Hardware: Not all parts are under the hood. CNC machining also supports aesthetic and functional components like gear shifters, infotainment brackets, and dashboard support structures.
- Prototyping & R&D: Prior to large-scale production, many automotive manufacturers rely on CNC machining to test the performance and safety of components. Roberson facilitates quick and precise transitions from CAD designs to real-world prototypes, aiding in design refinement and innovation.
- Electric Vehicle (EV) Components: CNC machining is key in the growing EV market, producing critical parts like battery housings, cooling plates, and custom mounts for electric drive units—each requiring precision design and specialized materials.
- Autonomous Vehicle Systems: Precision-machined parts are fundamental for the operation of sensors, control modules, and structural components in autonomous vehicles, ensuring high performance and reliability in complex driving systems.
- Performance & Aftermarket Parts: Through CNC machining, we produce high-performance custom parts such as intake manifolds, exhaust headers, and suspension upgrades, ideal for enthusiasts seeking enhanced vehicle performance and a personalized look.
At Roberson, we provide automotive part manufacturing services that meet the high expectations of the industry, whether you’re manufacturing five parts or five thousand. We maintain the highest standards of precision, consistency, and quality.
Types of Materials We Use for Lexington, KY, Automotive CNC Manufacturing
Material selection is pivotal in automotive manufacturing, directly influencing the performance, safety, and longevity of vehicle components. At Roberson Machine Company, we leverage a diverse array of metals and plastics, each chosen for its unique properties—strength, weight, corrosion resistance, and machinability—to meet the specific demands 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): Renowned for its strength and corrosion resistance, stainless steels are essential in applications ranging from exhaust systems to fasteners and drivetrain components. Hardened grades like 440 are particularly effective in providing wear resistance.
- Plastics (Delrin, PETGs, Nylon, PLAs, PEEK, HDPE, Glass-Filled Nylon): These plastics are excellent for producing lightweight, non-structural parts such as bushings, gears, and interior components. Certain materials, like PEEK, also offer resistance to high heat and chemical environments.
- Brass: Valued for its machinability and corrosion resistance, brass is ideal for manufacturing fittings, bushings, and valves used in fluid-handling systems and connectors.
- Titanium: Known for its lightweight yet exceptional strength, titanium is ideal for performance-driven applications where the strength-to-weight ratio is crucial, including exhaust systems and racing components.
