CNC machining, or Computer Numerical Control Machining, is a subtractive manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery.  CNC machining can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers.

CNC machining companies provide the advanced technology and expert craftsmanship necessary to bring intricate designs to life with precision and efficiency. These businesses offer everything from rapid prototyping to high-volume production, delivering custom parts that meet exact specifications for industries including aerospace, automotive, medical, and electronics.

In this guide, we explore some of the best CNC machining companies to partner with, showcasing their capabilities, expertise, and innovative solutions.

What is CNC Machining? 

CNC machining involves programming a combination of CNC tools to build a part directly from a CAD file. The machines etch out the design from a solid block of metal or other material to reveal the part shape. For larger or more complex parts, the parts will be created in sections, and the sections will be bonded back together to form a highly accurate part with a higher-quality surface that’s ready for plating, painting, or polishing.

How CNC Machining Works 

CNC machining works by using pre-computerized software and codes to dictate cutting instructions to factory tools. These codes tell the CNC machines what exact movement paths to follow when cutting a piece of material, such as metal or plastic, without a manual operator. By automating the process, CNC machining enhances both the precision and accuracy of production.

G-codes and M-codes (CNC machining languages) replace the need for manual input by instructing the machine on how to perform specific tasks during the cutting process. G-codes are responsible for the machine’s movements, while M-codes control auxiliary functions like starting or stopping the machine.

Why Should You Use CNC Machining? 

CNC machining offers a range of advantages in manufacturing, including: 

  • Increased accuracy and consistency: In industries like aerospace and healthcare, where even small design deviations can cause major issues, CNC machining allows teams to rapidly produce precise components. For example, aerospace parts such as airfoils, manifolds, and landing gear components often require tight tolerances of around 0.005 inches. CNC machining delivers this level of precision, producing complex parts from materials including aluminum, stainless steel, titanium, brass, and plastics.
  • Increased productivity: CNC machining can accelerate precision and timelines for tooling, progressive dies, and assembly fixtures in higher quantities. You can take designs to production faster, including prototypes with complex geometries via CNC prototyping. 
  • Cost-effectiveness: CNC machining is more cost-effective for large, simple parts such as plates for jigs, fixturing, threaded bars, and other linear parts. You can also use CNC prototyping to create prototypes, which allows you to fix design mistakes and make adjustments to products early on. This way, you can adjust the design without wasting materials or needing to redo entire parts, which helps save both time and money during production.
  • Reduced waste: During CNC machining, the production pathway of the machine is precisely detailed in the G-codes created from the CAD design. This ensures every part of the process, such as cutting and drilling, is done precisely, thereby reducing production waste.  
  • Range of durable materials:  Materials used in CNC machining are typically stronger and more durable and includes a wide range of options,  including metals, plastics, and composites.
