Frequently Asked Questions (FAQs)

#

What materials can be used for custom CNC machining?

You can use a variety of materials for custom CNC machining, including aluminum, stainless steel, copper, brass, carbon steel, and various plastics like Acetal, CPVC, and Delrin®.

#

What are the typical tolerances for CNC machining?

Typical tolerances for CNC machining are around ±0.1 mm, but tighter tolerances of ±0.02 mm or even ±0.005″ can be achieved depending on the specific machine and requirements.

#

How do I ensure proper workholding for my CNC machined parts?

To ensure proper workholding, you can use methods such as vacuum chucks, vices, clamps, and custom jigs. These methods help maintain the part’s position during high-speed machining.

#

Can I include text or lettering on my CNC machined parts?

Yes, you can include text or lettering. It’s recommended to use a minimum font size of 20 with sans-serif fonts like Arial or Verdana, and engraved text is preferred over embossed text.

#

What kind of surface finish can I expect from CNC machining?

CNC machining typically leaves visible toolmarks on the surface. For a smooth finish, you may need to opt for secondary finishes such as grained finish or powdercoating.
