Why Does the Automotive Industry Use CNC Machining?

Durable and precise CNC machined auto parts are vital for manufacturers and suppliers throughout the automotive industry. Consumers and businesses depend on reliable vehicles — every part involved must have a long lifespan and function as designed.


CNC machining has become one of the best methods for manufacturing reliable parts. CNC machined parts undergo multiple rounds of quality assurance and control to benefit your company and customers with durable, high-quality parts.


GN industry-recognized CNC machining process helps you:


  • Manufacture complicated, durable custom parts at the scale you require
  • Provide end-products with the quality and dependability necessary
  • Work with a wide range of materials to take on almost any project
  • Produce CNC car parts on time and on-budget


GN Corporations ensure that your vehicle parts are of the highest possible quality and are ready to provide your customers with a long-lasting and reliable vehicle.

GN’s CNC Machining Capabilities

GN Corporations has strengthened its CNC machining for the automotive industry by continually investing in the latest technologies and equipment. Multi-axis machines are at the heart of this process; some of GN’s CNC machines are:

5-Axis CNC Milling

5-Axis CNC Milling

Many of our projects utilize this machine for 5-axis CNC machining parts for automotive with the precision and durability necessary. We can produce complex structural parts and polyhedrons in a single operation.



9-Axis CNC Mill and Turn

5-Axis Water Jet Cutters

Some projects require the additional utility of water jet cutting to make cuts in a range of materials without risking the integrity of the material.



5 Axis Water Jet Cutters

9-Axis CNC Mill & Turn

Our 9-axis machine produces more complex shapes than a 5-axis machine. While many projects can be processed without needing a 9-axis machine, some of the highly specialized components found in the automotive industry will require this machine.

Frequently Asked Questions

  • What types of materials can be used in CNC auto parts?

    The automotive industry utilizes a wide range of materials. Our CNC automotive manufacturing is capable of using the following materials:


    • Steel
    • Plastic
    • Aluminum
    • Rubber
    • Copper
    • Titanium 

  • How does CNC machining compare to other car parts manufacturing and auto machining methods?

    The effectiveness of any type of manufacturing method depends on how it is applied. For example, CNC machining for automotive parts is a general-use method capable of producing a wide range of parts and has rapidly become a popular method throughout the industry.


    Another primary machining method for auto parts is gear manufacturing. CNC machining can handle some gear manufacturing projects; however, other projects require specialized gear-cutting machines.

  • How does the design of an auto part affect the CNC machining process?

    The auto part’s design will determine the type and size of machine GN will use during manufacturing. The auto part’s design also affects the number of operations involved in the overall process. 


    Different CNC machines offer varying depths of cuts while also impacting the speed of the overall process. The variety of involved variables is why working with a reputable CNC machining provider with the right tools and experience relevant to your industry is critical.

  • What are the advantages and disadvantages of automotive CNC machine services?

    CNC machines help our partners meet the competitive costs of the automotive industry. In addition, our machining processes help you stay on budget to compete on both price and quality.


    However, one disadvantage of CNC machines is that the process will not entirely complete some projects, such as the gear cutting mentioned above. Therefore, we will make sure to always include information about other necessary processes after delivery within our quotes.

  • How can the precision and accuracy of CNC machine auto parts be ensured?

    GN utilizes quality control equipment, such as CMMs, to ensure the quality of every component we manufacture is up to specifications. While our CNC machined spare parts leverage the latest technologies and equipment, we also have thorough quality assurance processes to ensure final deliverables meet your expectations.

  • How can CNC machining create complex geometries and shapes for auto part fabrication?

    One of the reasons why CNC machining has become so popular in the automotive industry is its sophisticated technology that provides the capability to reach extremely tight tolerances. Additionally, CNC processes can articulate in various directions to manufacture complex components.

  • What are the steps involved in the CNC machining process for auto parts?

    A typical process for our CNC milling part factories involves roughing out parts close to the general shape and size of the end product. From there, our CNC machines produce the final product through multiple operations. The number of operations required depends on the part’s design and materials.

  • How does CNC machining affect the lead time and cost of producing car parts?

    CNC machining is the fastest way to produce parts when considering other manufacturing methods. Therefore, leveraging CNC machining provides the best opportunity to be competitive for your components' costs and lead time.

  • How can CNC machining be used to produce small quantities of custom auto parts?

    CNC machines can produce any quantity of end-products, provided they fit within the machine's size capability. As a result, CNC metal parts factories have become a popular option for low-quantity orders.

  • Are there any special considerations for the CNC machining of aluminum and other lightweight materials for auto parts?

    CNC milling components factories consider the machining parameters for lightweight car parts. Primarily, we evaluate speeds and feeds, which will be faster with lightweight materials than other options.
