Precision Parts Machining in Kaukauna, WI


Introduction to Precision Parts
Precision machining is the foundation of 4M Machine LLC. For more than 20 years, we’ve specialized in manufacturing high-quality precision parts that meet the strictest requirements. Our family-owned machine shop in Kaukauna, Wisconsin, combines decades of machining experience with modern CNC technology to deliver components that perform consistently and reliably.
Whether you need replacement parts for legacy equipment, prototypes for new product development, or high-volume production runs, we deliver precision parts built to exact specifications. Every part is produced with attention to detail, from material selection to final inspection, ensuring performance you can count on.
Why Precision Parts Matter
In industries such as aerospace, automotive, oil and gas, manufacturing and food industry there is no margin for error. Parts must meet exact tolerances to fit and function properly. Precision parts prevent failures, reduce downtime, and improve product performance.
When tolerances are off, the result can be costly repairs, safety risks, or complete system failures. That’s why partnering with an experienced machine shop like 4M Machine is critical. We have the equipment, processes, and expertise to ensure every part we produce is accurate, consistent, and dependable.
