CNC machining guides for Irish buyers

Use these guides before you call a CNC shop. They help you choose the right process, prepare the right files, understand cost drivers, and brief suppliers in a way they can price.

If you are starting from scratch, read the cost guide, then the shop-selection checklist, then compare options in the supplier directory. If you already have drawings, jump to CAD prep and tolerances before using the quote request path.
