Most machine shops (production shops at least) are not purchasing new manual machine tools. Manual machine tools, even tool room (i.e. high precision) machines, like mills (and shapers) and lathes represent little or no value to commercial enterprises due to the labor costs and productivity relative to CNC machine tools. Thus, there are an abundance of used manual machine tools on the market, now they are irrelevant to the manufacturing industry. They remain difficult and expensive to move. They are very heavy take up lots of space, and may have special electrical power requirements. Their capability is also a function of tooling, which may, or may not be readily and cheaply available when obtaining the machine. So, despite the bargain that used manual machine tools represent, they are not likely impulse purchases. If I had the space, I would love a Monarch 612. You can get them for scrap prices, but its just far too impractical to consider. |

A manual tool that can still hold the same tolerances it did when it was new, in the hands of a skilled machinist, is worthless. Because a Haas machining center[1] can hold the same tolerances with an operator who has a 2 year certification degree.
So machine shops don't want (or need) the old manual tools, and yet they still work fine. Great way to build small arms on the cheap :-) If I ever retire to a ranch with space for a machine shop I'll collect these sorts of tools.
