There's always something around the corner, waiting to amaze you when you least expect it. This is an example of hen's teeth, if there's ever been one! And when you thought that the Boley Leinen uber-precise micro-milling machine couldn't get any cooler, this Prätecma (the Leinen successor co.) shows up on the flea-bay in Germany! It's the mythical FM 1 CNC machine, and look at the condition! This is a pure CNC (no manual option) micro milling machine. The working range of the X axis is 175mm, Y at 85mm, and Z at 125mm. So if you're thinking of putting a System 3R work holding solution on that table, you'd better do some serious math first 🤪 This is a spectacular extra compact and super rigid little setup. We can see that they're still using dovetails for each of the axis giving this little pup extra strength compared to modern dinky setups in this size. The spindle flies from 0-10K rpm using a 0.8kW spindle, and apparently still uses 8mm collets. So it is a crazy cool option to have if you need to make one-off parts. This little wonder is listed by seller "and-810606" on German ebay and all pictures are theirs. Just wanted to share this amazing piece of micro-mechanical history before it disappears into someone's workshop for another 40 years!!
