Frequently Asked Questions (FAQs)

# What is CNC Machining and How Does it Work?

CNC machining is a manufacturing process that uses computer numerical control to guide machine tools like lathes, mills, and routers. This automated process ensures high precision and accuracy by removing material from raw blocks to create custom parts.

# What Materials Can Be Used for CNC Machining?

You can use a variety of materials, including metals like aluminum, stainless steel, and copper, as well as plastics such as Acetal, Delrin®, and Nylon. The choice of material depends on the specific requirements of the part, including its intended use and environmental conditions.

# How Do I Design Parts for CNC Machining?

To design parts for CNC machining, use computer-aided design (CAD) software to create a detailed model. Ensure your design aligns with the six principal directions, and consider tool access limitations. Adding large fillets to internal corners and limiting cavity depth can also optimize your design.

# What is the Process of Creating a CNC Machined Part?

The process starts with designing the part using CAD software. Next, a program is created for the CNC machine, and the machine is set up with the proper cutting tools. The machine then follows the program to cut and shape the material. Finally, the part may need finishing and inspection to ensure it meets specifications.

# How Long Does CNC Machining Take and Are There Minimum Order Requirements?

The turnaround time for CNC machining typically ranges from 2 to 3 weeks, depending on the complexity and quantity of the parts. Some companies have minimum order requirements, such as a $125 or $300 minimum charge, but there are often no minimum quantity requirements.
