Overview of CNC Machining

The CNC machining process, use computerized controls to operate and manipulate machine tools that cut and shape stock material. Furthermore, the process follows the same basic production stages as all CNC machining processes, which include:

  • Creating a CAD model
  • Creating a CNC program from the CAD model
  • Configuring the CNC machine
  • Carrying out the machining operation

The CNC machining process starts with the design of a 2D or 3D CAD part. The completed design is then exported to a CNC-compatible file format and converted by CAM software into a CNC machine program, which instructings the machine’s actions and tooling movements across the workpiece. Before running the CNC program, the operator must first prepare the CNC machine by attaching the workpiece to the machine’s work surface (worktable) or work holding device (e.g., vise) and attaching the milling or turning tools to the machine. Depending on the specifications and requirements of the machining process, the CNC machine will use different cutting tools such as mills and drills. When the machine is ready, the operator starts the program via the machine interface, instructing the machine to perform the machining operations.

Benefits of CNC Machining

CNC machining centers are quick and precise, allowing for the efficient production of complex and specialized products. CNC machining has lots of advantages, including:

Cost Savings

Every business seeks ways to reduce costs while maintaining quality. CNC Machining enables the efficient production of complex and specialized products because they work faster and more accurately.


When a CNC machine is running, there is no bending or crouching required to operate the machines. So, there should be fewer workplace accidents and less fatigue, which reduces the risk of human error in the machining process significantly. And also, the safety and ergonomic conditions for workers are greatly improved.


CNC machines can operate continuously with little downtime. A fully-automated CNC machining facility can keep running without interruption 24 hours a day, seven days a week.


One of the most significant advantages of CNC machining is its versatility. CNC machining enables manufacturers to cut or shape a wide range of materials while maintaining quality and efficiency.

CNC milling are ideal for a wide range of complex, high-quality production runs of all sizes. CNC machines will also save you a lot of time and money because of their operational efficiency and lower labor costs.

Frequently Asked Questions

We accept 3D CAD files in STL, STP, STEP, OBJ IGS or IGES format and 2D drawings(jpg, png, gif, bmp, pdf) with dimensional details and specific manufacturing requirements.

We respond within 2 hours after your request. Princing quote will be send within 8 hours. If the quote is delayed, we will notify you as soon as possible.

Yes, master models are used to create silicone molds for vacuum casting and can be made from any rigid solid that can withstand heat up to 100 °C. Models used for CNC machining will be 3D scanned to create a CAD/CAM program for production.

Quality parts less than 1000pcs can be made in as fast as one week if you provide complete 2D and 3D CAD models. More complex parts requiring other special features will take longer. As for shipping, most of our shipments are via air freight, which can take 5-7 days from China to Europe or North America.

We respect your intellectual property. None of your information, images, files or likenesses will be shared with any third party, and it will not be used for any advertising, marketing, or promotional use without your explicit written authorization.
