Frequently Asked Questions (FAQs)

# What is CNC Machining and What is it Used For?

CNC machining is a manufacturing process that uses computer-controlled machines to automate the production of custom parts. It involves precise cutting tools to remove material from metal or plastic blocks, creating simple to complex shapes for various industries like aerospace, automotive, and medical.

# What Types of Materials Can Be Used for CNC Machining?

You can work with a wide range of materials, including metals such as aluminum, steel, stainless steel, and titanium, as well as plastics like ABS, acrylic, nylon, and more. Each material is chosen based on the specific requirements of your project.

# Do You Need to Provide a CAD File for a Quote?

Yes, you need to provide a CAD (Computer-Aided Design) file to get a quote. This file is essential for the CAM software to generate the toolpath and ensure the part is machined accurately. Common formats include .STL, .STEP, .IGES, and .DWG.

# What is the Typical Lead Time for CNC Machining Projects?

The lead time varies based on the complexity of the project, material availability, and production volume. Generally, simple parts can be machined in a few weeks, while more complex projects may take longer. Expedited options are often available for urgent projects.

# Can You Order Small Quantities of Custom Parts?

Yes, you can order small quantities, even just one part. Many CNC machining services welcome small orders and offer price reductions for larger quantities. There may be a minimum order charge, but this varies by provider.
