CNC Machining Services – Precision Milling, Turning & Manufacturing

At DSI Manufacturing, our CNC machining services deliver the accuracy, speed, and consistency modern manufacturing demands. From one-off prototypes to high-volume production runs, we specialize in producing tight-tolerance components that meet the highest industry standards. Located in Rogers, Minnesota, and backed by over 40 years of experience, DSI is your trusted partner for precision machining.

With advanced multi-axis CNC milling and turning equipment, highly skilled machinists, and integrated CAD and CAM programming, we ensure that every part we produce is precise, reliable, and ready for assembly or end use.

Why Choose CNC Machining?

CNC (Computer Numerical Control) machining uses software-controlled tools to cut, drill, turn, and shape parts from raw material. This process offers significant advantages:

Unmatched Precision – Consistent results with tolerances within thousandths of an inch.
Scalable Production – Cost-effective for both prototypes and full production runs.
Complex Geometry – Multi-axis machining creates intricate shapes not possible with manual methods.
Material Flexibility – Works with metals, plastics, and composites.
Repeatability – Identical parts across multiple runs ensure compatibility and quality.

Our CNC Machining Capabilities

CNC Milling

DSI operates advanced CNC milling centers, including 3-axis, 4-axis, and 5-axis machines like the HAAS VF3SS and VF4. Our milling services include:

Complex contouring and 3D surfacing
High-speed machining for faster cycle times
Precision drilling, tapping, and pocketing
Aluminum, steel, stainless, brass, plastics, and composites machining

CNC Turning & Swiss Machining

Our CNC turning centers and Swiss lathes produce high-quality round parts, shafts, and threaded components. This includes:

Live tooling for complex features
High-volume runs for cost efficiency
Tight tolerance diameters for demanding industries

Surface Grinding & Secondary Operations

To complete your project, we offer grinding, deburring, tapping, reaming, and finishing — ensuring every part meets performance and cosmetic requirements.

Assembly & Integration

Many machined parts are just one step in a larger system. Our in-house assembly services ensure your machined components are seamlessly integrated into sub-assemblies or full products.
