Our Capabilities and Equipment

Our shop is equipped with a wide range of tools and machines to handle a variety of machining tasks. We provide both manual and CNC machining, giving us the flexibility to meet the specific needs of each project.

When it comes to CNC milling services, our facility is prepared to handle intricate geometries and multi-surface components. We use Haas VF series mills, including 4th and 5th axis-ready machines, which allow for efficient machining of complex parts without multiple setups. Our Kitamura Mycenter machines add additional precision for smaller, high-detail parts. Every mill is programmed and operated by experienced machinists to achieve the exact tolerances required.

For CNC lathe machining, we use Mazak QTN and Mori Seiki SL series lathes, capable of producing cylindrical parts, shafts, bushings, and fittings with consistent diameters and excellent surface finishes. Our lathes handle both short runs and larger production quantities, making them versatile for many industries. By combining lathe operations with milling or secondary processes, we provide fully machined parts ready for assembly or further finishing.

Our shop also includes manual milling machines, surface grinders, band saws, and sheet metal equipment. This range allows us to manage projects that require multiple processes under one roof. By keeping manual capabilities alongside CNC technology, we maintain flexibility and control over parts of every shape and size.

Precision CNC Machining Services

Accuracy is critical, and our precision CNC machining services deliver results you can rely on. Every project receives careful programming, setup, and inspection to ensure that the final part meets specifications. We use SolidWorks and Mastercam software to program complex components and optimize cutting paths for efficiency and precision.

Our machinists are experienced at interpreting blueprints and selecting the right tools, speeds, and feeds to achieve the best results for each material. Whether you need aluminum, stainless steel, titanium, or specialty alloys, we can adjust our processes to maintain accuracy and part integrity. Every finished component is measured and inspected, so you can trust that what we produce is consistent and reliable.

By focusing on precision, we help reduce scrap, minimize downtime, and ensure that every part fits perfectly into your assembly. This approach is particularly important for industries like aerospace, medical devices, automotive, and industrial equipment, where tolerances can be extremely tight and the quality of each component affects overall performance.

CNC Milling Services

Our CNC milling services allow us to create parts with multiple faces, complex features, and tight tolerances. Using our multi-axis milling centers, we can machine intricate components efficiently. The 4th and 5th axis capabilities reduce the need for multiple setups, which saves time and improves consistency.

We handle parts ranging from simple plates and brackets to intricate geometries for mechanical assemblies. CNC milling is ideal when accuracy, repeatability, and surface finish are critical. Our team can advise on design adjustments that optimize machining efficiency without sacrificing functionality, helping to produce parts that meet both design and budget requirements.

CNC milling also allows for fast production of prototype parts, which helps your team test designs before committing to full production. Quick turnaround on prototypes and small batches gives you flexibility and confidence in your final design.

CNC Lathe Machining

For parts that require turning, threading, or cylindrical precision, our CNC lathe machining services are highly effective. Our lathes can produce consistent diameters, smooth surfaces, and accurate threads, making them suitable for shafts, bushings, fittings, and other cylindrical components.

We combine lathe operations with milling or secondary machining as needed, providing complete parts ready for installation. By controlling the entire process under one roof, we can manage tolerances and ensure that every part meets specifications without delays.

CNC lathe machining also supports both short and long production runs, allowing you to scale projects without sacrificing quality. Whether you need a small batch of parts for testing or thousands of components for full production, our shop has the capacity and expertise to deliver.

Prototyping to Full Production

Spring Mills Manufacturing supports projects of any size. We can produce a single prototype part, perform short-run manufacturing, or manage full-scale production. Each stage receives the same attention to accuracy and quality.

Prototyping allows you to test designs and make adjustments quickly. Once the design is finalized, we can transition smoothly to larger production runs without changing suppliers or processes. Maintaining consistency across all quantities ensures that every part fits perfectly and performs as expected.

We adapt to your schedule and requirements, providing flexible solutions that meet tight deadlines without compromising quality. The combination of advanced equipment, skilled machinists, and efficient processes ensures that we can handle projects that vary in complexity and scale.

Quality Assurance and Inspection

Quality is built into every step of our machining process. We inspect parts at multiple stages to confirm dimensions, surface finishes, and material integrity. By catching issues early, we prevent delays and ensure that finished components are ready for immediate use.

Our quality process includes measuring key features, checking tolerances, and verifying that each component meets customer requirements. This approach reduces errors and ensures consistent results, giving you confidence that the parts you receive will fit and function correctly.
