Cer-Mac Inc. is a turn-key machine shop with an expert CNC milling team that works with many CNC milling machines to produce CNC milled parts that meet your needs. Our team is fully equipped to service your CNC milling and 5-axis machining needs.
What sets Cer-Mac Inc. apart from other CNC milling and turning facilities is our 5-axis milling capabilities. Our 5-axis milling centers are the cornerstones of our CNC milling department.
Our CNC milling process starts by working directly with you to learn more about what parts you need to be produced. We know about your manufacturing needs, how many parts you need to be machined, what features you may require, and if you need any special final surface finishes. After programming, we choose a CNC milling machine that makes sense for the machining process.
These CNC milling service options include 5-axis milling, high spindle milling, and 3-axis CNC milling. After we find the CNC milling process that suits you, we’ll program our CNC milling machine to cut high-quality parts that meet your particular specifications. If your project calls for 5-axis machining, we can handle that as well.
Our computer-controlled milling process includes specifications like +/- 0.001-inch tolerances, and the ability to machine a 36-inch cube. We can also do plate work on pieces up to 80 to 120 inches, drill holes as small as 0.005 inches, and provide thread milling capability.

Cer-Mac Inc. specializes in machining precision parts for multiple industries, including aerospace, automation, defense, biotech, fiber optics, medical, oil, seal pump, optics, and semiconductors. CNC milling can be used for parts like:
You can also utilize this process with Swiss Screw machining for knobs, needle valves, nozzles, pins, pivot rods, electronics, punch blanks, sleeves, spacers, valve bodies, and valve stems.
Achieving a superior finish with CNC milling begins with appropriate machine selection. The three primary CNC milling machine types and accompanying advantages/disadvantages include:
Other advantages include ease of tool setup and changeovers, cost-effectiveness in comparison to other milling options, and a high degree of accuracy.
Despite the versatility and affordability of vertical CNC milling, vertical milling machines may not be the most effective option for multi-sided machining applications.
Although horizontal CNC milling is great for higher-volume production runs and a spectrum of multi-sided machining projects, horizontal CNC milling machines are not always the best option for certain geometries or complex component types that may be better served with a 5-axis tool orientation.
Although 5-axis machining opens up many newfound possibilities for creative and highly precise part design, these machines are expensive to own/operate. Additionally, there is a significant level of complexity involved in the CAM programming process. Since multiple cutting tools are operating simultaneously, great care must be taken during setup to avoid programming errors and tool-pathing issues.
Computer-controlled, rotating cutting tools produce a shape or form with great reliability and repeatability.

CNC milling services provide repeatability and consistency with every run. From simple, single-plane panels and parts to ultra-complex geometrical components used in aerospace technologies, CNC milling services offer the perfect balance of defect-free affordability and production efficiency.
CNC milling ensures outstanding accuracy with the ability to achieve tight tolerances and polished surface finishes on all planes. Since part designs are saved in our internal system, CNC milling also makes it easy to produce multiple identical components of various size and complexity.
In addition to the value of large scale, defect free production runs , CNC milling is also an invaluable production option for creating and modifying prototypes and trial components. Whether you want to test a different material, modify an existing shape, or revise a range of component iterations, customizing your designs is optimized with the adaptable tools and cutting parameters available with CNC milling.
Our CNC turning and CNC milling equipment is primarily utilized for high-nickel alloys and metals such as steel, aluminum, titanium, and brass. CNC milling is also appropriate for a range of plastic polymers, composite materials, and even certain ceramics.
Wherever there is a need for strong, precise, and cost-effective component quality, our vertical, horizontal, and 5-axis milling services promote enhanced part performance and longevity.
From heavy-duty engine components found in automotive manufacturing to lightweight aluminum and heat-resistant alloys found in aerospace manufacturing, our vertical, horizontal, and 5-axis machining capabilities support all facets of innovation.
In addition to cutting-edge aerospace applications, our CNC milling expertise is commonly utilized for other applications such as medical implants, tool and die making, and:
