How Long Does CNC Machining Take?

CNC machining benefits almost every industry in ways you may not be aware of. It is a solution for many problems, from precision to mass production.

If you are just starting to get into CNC machining, you may wonder: How long does CNC machining take?

How to Estimate CNC Machining Time?

Although this seems like a straightforward question, the answer ranges widely depending on the complexity of the produced part. For example, producing simple parts may only take a few hours. On the other hand, complex parts requiring 5-axis CNC machining may take weeks.

Here is our CNC machining guide to help you understand why some parts take so long while others do not.

CNC Machining

CNC machining, also known as computer numerical control machining, is a form of automated precision machining. It is known for its high accuracy and extreme precision, allowing for the manufacturing of very complex parts to precise specifications.

Furthermore, CNC machining can achieve complexity and intricacy beyond traditional precision machining techniques. It can achieve this at a fraction of the cost. Even complex parts can be manufactured economically and efficiently!

CNC machining services are used to manufacture customized machined parts from raw materials, forgings or castings into personalized components. Every industry relies on precision machined parts to function, from the medical industry to the optical industry, custom machining is absolutely essential.

Due to different industry demands, the time range for production varies widely, from very simple parts to complex ones. After all, you cannot expect a simple part to require the same amount of production time as a part that requires a 5-axis machine.

Types of CNC Machining Services

Another process that affects how long CNC machining takes is the technology or process type you need. Typically, you can choose from the following options:

• Milling - using rotating cutting tools on a stationary workpiece;

• Turning - rotating the workpiece to make contact with a cutting tool (lathe is very common);

• Drilling - using a cutting tool to drill holes in the workpiece;

• Tapping - removing material from within the workpiece, creating internal cavities;

• Sawing - using a saw blade to make a narrow cut in the workpiece;

• Grinding - performing shallow cuts to remove material.

Although some techniques are relatively simple, others are more complex and require more time to complete.

In addition to various technologies, your CNC machining workshop may also provide additional services. These include:

• Project Management - You can rely on end-to-end professional expertise to ensure the scope, quality, cost, and schedule of your project from design to production.

• Procurement - Your machine shop should provide experienced advice and high-quality procurement of materials to deliver the best parts to you.

• Engineering - A professional engineering team can handle your design, select the right tools, and input CNC programming, providing flexibility, shorter delivery times, and better work quality.

• Quality Control - In most machine shops, control plans, failure mode and effects analysis (FMEA), supplier quality engineering, production checks, and production part approval process (PPAP) are included in the quality control process.

These additional services can ensure that your service is seamless from start to finish, shortening delivery times.
