CNC Machining

I conducted a study in September 2022 to identify the price for the CNC machining of a simple part from various online suppliers.   The part consisted of a simple 304 stainless hollow cylinder.   Many suppliers offer USA sourced and international sourced pricing.   Typically, the price for international sources was 50% of the USA price, even with taxes and shipping.   However, unless the online supplier assists with the import of the parts, the logistics of importing parts internationally can be expensive and a lot of work.   Many suppliers provide options in terms of a price premium for both USA and international sources to expedite the manufacture of your item.   Lead times can range from one day to 30 days.   The normalized ranking of the suppliers surveyed (low rank = lowest cost) is shown below.
