Precision CNC Machining Center

Machine Shop

With a world-class Machine Center and a team of experienced CNC machining operators, C4 Welding delivers your finished parts and products with exceptional accuracy. The addition of the SNK RB6M Double Column Multi-Center expands our capacity to service our customer’s needs with shorter lead times, increased project control and fewer associated logistics challenges.

Precision CNC Shape Cutting

All manufacturing projects start with design. Our dedicated project managers will review your supplied drawings and define a statement of work. Alternatively, take advantage of C4 Weldings in-house design programmers that will process your initial concepts and drawings. Our team will provide three-dimensional models of simple or complex parts, such as screw threads or multiple sided flat surfaces using the latest computer-aided design (CAD) software.

Approved technical drawings are interpreted by modern CNC machining systems used for shaping parts. Using best-in-class CNC lathes by SNK, machine operators are well equipped to finish products to exact specifications.

Large Part Machining

Increased customer demand for larger and larger welded and machined structures led C4 to bring world-class large part precision machining capabilities to our shop floor with the installation of a SNK RB6M Double Column Multi-Center.  

SNK has manufactured Double Column Machining Centers for over 50 years, with over 5,000 units installed world-wide. RB-M Series Machining Centers deliver productive 5-face, single set-up machining. The rigid double column design and construction assures peak precision and excellent work envelope access. This machine has both an automatic tool changer and right-angle attachment changer. In addition to X,Y & 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 service our customer’s needs better with shorter lead times, increased project control, and fewer associated logistics challenges. C4 has acquired highly-experienced large part programmers/machinists dedicated to supporting this new mill.

Small Part Machining

It all has to fit. CNC small part machining requires precision and accuracy. C4 Welding has the proven experience and expertise to move your small parts from design and into production. The machine shop is complete with vertical and horizontal turning machines, CNC tool room mills and lathes. Most importantly, our team of experienced programmers machinists makes C4 one of the top contract manufacturing companies in Minnesota.
