I see Tormach just announced their new product - a 2/3 sized PCNC, PCNC 770. 10000 RPM, 130 ipm.
See http://www.tormach.com/blog/ They go on sale tomorrow. $6200.

i wish they had a 10k rpm spindle and 130 ipm rapids/feeds on the 1100.
that does look like a pretty cool little machine. i wonder what the axis travels are.
Now there's the machine I really wanted when I bought my PCNC1100 three years ago.

Right after I posted, I called this (in my head) as the second reply. And I agree.Originally Posted by 300sniper
On one hand, I wanna think they'll sell a buttload of these to people who value the reduced power and footprint requirements. But on the other hand, I'm wondering if there's really that many people who can come within less than $1500 of affording the big boy, but can't manage to find the space and power.
I would have been very satisfied with a machine the size of a Sherline but built like a Tormach. Almost all of my work is less than 6" long, of brass and plastic and aluminum, a lot of 2.5D and 3D work with 1/8" and smaller bits. Sure, I've taken advantage of the 1100's working envelope, but that's "bonus" beyond my core interests. And a speeder to 30krpm--that would probably never leave the spindle for me...

I don't think the new mill is targeted as an entry level machine, more at being good at what the PCNC 1100 isn't. So now the question is, "sell the PCNC 1100 or buy a Speeder"?
The video also suggests that you can fit the Speeder to the new machine for a wacking 30,000 rpm! Maybe the new machine is going to need a "Reducer".
Choices, choices, choices.

As someone that had to disassemble the 1100 to move it into my basement, I can appreciate the features to aide in moving the 770. However, after using the 1100, I would not want to give up on any work envelope (I assume it is smaller due to the 2/3 sizing ratio).
It sure would be nice to have the 10 k rpm spindle. I'm curious as to whether the 1100 can be upgraded to that speed in the future...

i don't know enough about the mechanics of the 1100 to even know what the limiting factors are on the spindle speed and rapid/feed speeds.
i thought i read here that the spindle bearings may not be good for that speed. i don't know if different bearings could be fitted or an entirely new spindle cartridge could be designed to fit that would allow higher spindle speeds. as far as rapid speeds, would that be the steppers that can't handle it? is this new machine still using steppers? i wonder if the table is lighter weight allowing for faster rapids without loosing steps?
It does look like a decent small machine I do hear alot of people wanting a small machine with high rpm so I guess it will turn out good as for the rapids maybe a different screw makes this possible? It is a little on the expensive side for the size though. Looks like a good hobby machine.
I forgot to write the numbers down, but the work envelope is smaller.
As jealous as I am of the increase rapids and spindle speed, I couldn't step down to a smaller work envelope. For me this could be a great machine if devoted to secondary operations Considering all the tooling interchanges with the pcnc 1100 it would also be a small investment.
I personally am waiting with cash in hand for the speeder. I have a very early machine (60ipm rapids), but find more often then not my limiting factor is spindle speed.
