Precision Automotive Machining for High-Volume Production
At Camco Precision Machining, we deliver high-quality, precision-machined automotive parts to OEMs and automotive manufacturers. Our state-of-the-art CNC machining, including CNC Swiss machining, CNC turning, CNC milling, and screw machining, enables us to produce custom automotive components that meet the stringent requirements of the automotive industry. Whether you need low-volume custom parts or high-volume production runs, we offer a comprehensive range of services designed to ensure the highest standards of durability, performance, and precision in bulk production.
We specialize in manufacturing precision automotive components for a wide range of applications. Our parts are designed for use in engines, drivetrains, suspension systems, and other critical automotive systems. Whether you need one-off parts or require high-volume production for bulk orders, we can meet your needs.
Here are some examples of the small-to-medium-sized parts we regularly produce for high-volume production:
- Engine Components: Pistons, crankshafts, camshafts, and cylinder heads.
- Drivetrain Components: Axles, drive shafts, CV joints, and differentials.
- Suspension System Parts: Control arms, shock mounts, bushings, and mounting brackets.
- Transmission Parts: Shift forks, gears, and synchronizers.
- Fuel System Components: Fuel rails, injector holders, and fuel line fittings.
- Custom Fasteners: Bolts, nuts, washers, and screws for automotive applications.
Each part is precision-machined to meet the exact specifications required for performance, safety, and reliability in automotive systems, whether you’re looking for bulk production or custom solutions.

We use a variety of high-performance materials tailored to the demanding conditions of automotive systems. Our material expertise includes:
- Aluminum Alloys: Ideal for lightweight components like engine blocks, brackets, and transmission housings.
- Steel Alloys: Used for strong, durable parts like gears, crankshafts, and drive shafts.
- Stainless Steel: Known for its corrosion resistance and strength, perfect for fuel system parts and fasteners.
- Titanium: Lightweight and strong, used for high-performance engine components and exhaust parts.
By using the right material for each application, we ensure the optimal performance and longevity of every automotive part we produce, from custom parts to high-volume production.
Our facility is equipped with the latest CNC technology, enabling us to produce parts with tight tolerances and high-quality finishes. We are capable of handling a wide range of automotive machining needs, including:
- CNC Swiss Machines: Ideal for high-precision, small parts with complex geometries. Perfect for engine components and fuel system parts in high-volume production.
- CNC Turning: Used for symmetrical parts like crankshafts and drive shafts, ensuring precise dimensions and surface finishes, whether in low-volume or bulk production.
- CNC Milling: Perfect for producing complex parts with multi-dimensional features, including mounting brackets, control arms, and gear components for bulk orders.
- Screw Machining: Ideal for high-volume production of screws, bolts, and nuts used across various automotive systems.
Our capability to handle various materials and machining techniques gives us the flexibility to meet the unique needs of every automotive application, from custom parts to large-scale production.
In the automotive industry, precision is critical. At Camco Precision Machining, we ensure that every part is produced to the highest standards. Typical tolerances we achieve include:
- Dimensional tolerances as tight as ±0.0001 inches.
- Geometrical tolerances such as perpendicularity, parallelism, positional tolerances, and profile as per GD&T (Geometric Dimensioning and Tolerancing).
- Surface finishes that meet RA (Roughness Average) requirements as low as 32 microinches.
- Thread tolerances for tight-fitting bolts, nuts, and screws used in high-performance automotive systems.
We take pride in the quality of our work and ensure that every part undergoes rigorous quality control to meet OEM standards. This is particularly important in high-volume production, where consistency and quality are essential.
- Expertise with OEMs: We have extensive experience working with OEM manufacturers to produce custom automotive components that meet the most demanding performance and safety standards, including high-volume automotive machining.
- State-of-the-Art CNC Technology: Our CNC Swiss machines, CNC lathes, milling machines, and screw machining capabilities enable us to handle complex geometries and tight-tolerance components required for automotive applications, including high-volume production.
- Material Expertise: We are highly skilled in machining a wide range of automotive-grade materials, including aluminum, steel, stainless steel, and titanium, ensuring parts perform under extreme conditions.
- Quality Assurance: We adhere to the strictest quality control measures, ensuring every part meets OEM specifications and delivers reliable performance in automotive systems.
- Timely Delivery: We understand the importance of on-time delivery in automotive manufacturing. We are committed to meeting your project timelines, especially in bulk production, without sacrificing quality.
