Frequently Asked Questions (FAQs)

#

What is Custom CNC Machining?

Custom CNC machining is a process that uses computer-controlled machines to create and modify parts from metal or plastic. It involves loading a workpiece into a CNC machine, which is programmed using CAD and CAM software to make precise cuts.

#

What Materials Can Be Used in Custom CNC Machining?

You can use a wide range of materials, including metals like aluminum, steel, and titanium, as well as rigid plastics such as PEEK and Teflon. The choice of material depends on your specific application and requirements.

#

What Are the Tolerances for Custom CNC Machining?

Custom CNC machining can achieve tight tolerances, typically +/- 0.005″ for metals and +/- 0.010″ for plastics. However, you can also request even tighter tolerances, such as sub +/- 0.001″, depending on your needs.

#

How Long Does Custom CNC Machining Take?

The lead time for custom CNC machining can be as short as 3 business days for standard orders. This quick turnaround is ideal for both prototyping and production, ensuring you get your parts quickly and efficiently.

#

What Kind of Surface Finish Can I Expect from Custom CNC Machining?

The standard surface finish from CNC machining is as-machined, which typically has a roughness of 125 Ra or better. You can also opt for additional finishing options like graining or powder coating to achieve a smoother finish.
