With few exceptions, Machine Shops each serve a local market rather than catering to a national (let alone an international) customer base. In turn, most of them concentrate on jobs that can be considered in terms of general rather than specialized machining. In other words, they produce parts by turning, milling, boring, and grinding metal, but they don't often go beyond these processes. Given this basis -- and recognizing the sheer volume of firms of so similar a nature -- it is considered useful, if only as a matter of convenience, to index Machine Shop sites under a series of subcategories based on location. Note: Shops that (regardless of what they may call themselves) concentrate on a particular type of machining as opposed to a variety of general operations are, relatively speaking at least, much less numerous -- and in consequence their customers are more widely scattered. Accordingly, sites of this kind are collected -- and retained -- under several appropriate headings such as Grinding, Spinning, and Stamping. In a few cases, too, shops focused on less common machining processes (as, for example, thread rolling and cold heading) are allocated to the main Machine_Shops category. Additional note: Tool and Die Shops differ from Machine Shops and have a category of their own. Their emphasis is on producing tooling, patterns, dies, fixtures, gages, and parts that involve one form or another of special or sophisticated machining. As with Grinding companies and their like, their numbers aren't too unmanageable, and there is no benefit in breaking them up into location subcategories.
