Precision Machining Services

C4 Welding has a world-class machine shop and a large team of experienced operators to deliver precision machining services that result in finished parts with exceptional quality and accuracy. We are always expanding this shop, investing in the latest equipment to ensure that our customers receive only the best precision-machined products. For instance, the addition of the SNK RB6M Double Column Multi-Center expands our capacity to service our customers’ needs with shorter lead times, increased project control, and fewer associated logistical challenges.

Ensuring Precision from Start to Finish

All manufacturing projects start with a design. Our team of engineers will review your supplied drawings, define a statement of work, and process your initial concepts and drawings to ensure manufacturability. Approved technical drawings are then interpreted by modern CNC machining systems to manufacture the parts. Using best-in-class CNC machines, the operators can then finish products to exact specifications.

Large Part Precision Machining Services

An increased demand for larger welded and machined structures than typical led C4 Welding to integrate world-class precision machining services for extremely large components with the installation of an SNK RB6M Double Column Multi-Center. The RB-M Series Machining Centers deliver productive 5-face, single-set-up machining. The rigid double-column design and construction assure peak precision and excellent work envelope access. 

This machine has an automatic tool changer and a right-angle attachment changer. In addition to the X, Y, and Z axes, a CNC-controlled 4th axis (W) expands machining capability and provides exceptional rigidity for rigorous cutting conditions. The generous quill stroke (Z) allows exceptional access to cavities, simplifying deep-hole cutting.

The addition of this machine allows C4 to better service our customers’ needs with shorter lead times, increased project control, and fewer associated logistics challenges. We’ve also added to our team several highly experienced programmers/machinists with extensive knowledge of machining large components, all dedicated to supporting this new mill.

Small Part Machining

Precision and accuracy are paramount in CNC machining for small parts–especially for parts requiring a precision fit, no questions asked. C4 Welding has the proven experience and expertise to move your small parts from design to production. The machine shop is complete with vertical milling and turning centers, CNC tool room mills, and different manual equipment. Most importantly, our team of experienced programmers and machinists makes C4 one of Minnesota’s top contract manufacturing companies.
