CNC Machining Processes

CNC Milling Service

CNC Milling uses 3-axis milling and 5-axis indexed milling to rapidly cut a choice of more than 30 engineering-grade thermoplastics and metals into complex shapes and precision components.

As one of the subtractive manufacturing processes, milling removes material from bulk by using tools to cut/drill a workpiece. CNC Milling is capable of producing parts with high accuracy at a high speed.

CNC Turning Service

CNC Turning uses a lathe to create detailed functional prototypes and end-use parts with cylindrical features. It removes material from bulk by rotating the workpiece.

CNC Turning is great for the processing of cylindrical parts, capable of producing high-quality parts cost-effectively.

Overview of CNC Machining

What’s CNC machining?

CNC (Computer Numerical Control) machining is a manufacturing technique that uses high-precision machine tools to remove material. It uses a variety of sharp cutting tools, through the computer to precisely control various shapes and sizes to achieve the final design. It can be used to manufacture various precision production parts. Common CNC machine tools include vertical milling machines, horizontal milling machines, lathes, and router planers

How does CNC machining work?

Initially, our engineers created programming instructions on the computer-based CAD drawing model provided by the customer. When the tool path required by the part is determined, the computer will send the command to the CNC machine tool in the form of “G code”. After the machine tool receives the code, it will move and quickly rotate the cutting tool according to the instruction so that it can cut at the correct position until the part is completed.

Why choose CNC machining?

There are many benefits of CNC machining, it is a fast, accurate and universal machining solution. Once the instructions are created and the machine tool is programmed, any number of parts can be manufactured. It is designed for precision manufacturing and reusable use, with cost-effective and high scalability. Besides, CNC machining can also use a wide range of materials, including aluminum, copper, titanium, plastics, etc. This is why CNC machining is so popular.

What materials can be used with CNC machining?

There is a wide range of materials that can be used in CNC machining, including metal materials such as aluminum, copper, stainless steel, titanium, and we also can machining hard plastics materials. If you still have questions, you can contact us for more detailed information about machinable materials.

What’s the cost of your CNC machining parts?

The costs associated with CNC machining mainly include materials, machining time, quantity, and machining difficulty. In order to further determine the cost you need, you can provide us with your CAD drawings, and we will send you a manufacturing analysis and quotation within a few hours.
