Grand Valley Manufacturing Co. is a leading manufacturer specializing in CNC milling. We employ cutting-edge CNC mills to produce quality parts that meet your requirements. You can trust our team to efficiently manufacture large and heavy components for various applications in many industries.

What is CNC Milling?

CNC milling is a mechanical machining process that relies on computerized controls to progressively and accurately remove material from a workpiece. CNC refers to computer numerical control, which is widely used today to automate the milling process for a more consistent outcome.

A CNC mill or milling machine consists of a cutting tool mounted on a rotating spindle. The workpiece is securely mounted to a platform or a table as it spins in different directions, allowing the tool to effectively work on many angles.

A more sophisticated CNC mill can have five or more independent motion axes to make more intricate shapes. It eliminates the need for multiple setups or fixtures and can complete the job in one setup which equates to efficiency in process and competitive pricing.

Advantages of CNC Milling

CNC machine milling provides numerous benefits, such as the ability to work on large parts. It’s why we specialize in this manufacturing capability to get results that will drive success to all your large-scale projects.

Typical benefits of CNC milling include:

  • Improved reliability and better consistency: Compared to manual operations, CNC milling enables us to follow precise specifications without constant attention from an operator. It significantly reduces human error, which improves accuracy even on complex geometries.
  • Enhanced productivity and endurance: CNC milling machines can work around the clock as long as needed. It increases productivity even with the help of fewer engineers or skilled workers.
  • Quick turnaround: A CNC milling machine can create many parts nonstop if programmed correctly. It allows us to meet deadlines while ensuring fewer errors. In addition, the more high-tech the machine, the faster it can complete a job.
  • Cost-effectiveness: CNC milling is cost-effective as it eliminates human labor and reduces waste due to its precision. It saves time, money, and resources in the long run. It also offers high output rates with minimal mistakes at low production costs.
  • Complete complex jobs: We handle large or small production runs with the help of our CNC milling machine. Its tools can complete difficult tasks with the tightest tolerances or the most intricate forms.

Applications of CNC Milling

CNC milling is a versatile process that multiple demanding industries rely on, including Aerospace, Construction, Agriculture, Transportation, Marine, and Defense, to name a few. Therefore, its range of capabilities is vast and can be utilized for numerous applications.

Example applications are as follows:

  • Transportation Frames
  • Asymmetrical Components
  • Deck structures
  • Power Generation Components
  • Large Fabrications
  • Hull structures
