Special Lathe Wanted

[MrGrunzy]

Any suggestions ?

The part we want to make will come from:
3" Round stock WOOD
18 inches long
Enough bed length to mount auxiliary slides to plunge forms on both ends while running a contour on the OD.

So the process is:
hydraulic feed thru the spindle;
clamp;
plunge and simultaneous contour,
cutoff,
next feed.
Horsepower needs are reasonable because the stock is wood.
Since Mori's seem to be fairly compact, do I need an extended bed machine?

I was led to believe that Mori made machines with spindle speeds in the 4000 RPM range with an oversize spindle that has a thru hole of 3 1/8.
The designations I took down in a brief conversation with a former supplier were SL25, B-500, from one he had that had the standard A 26 2 7/8 dia thru

hole.

High speed and collet gripping seem to go
together. CNC axis, if fast enough could provide motion to steady
rest/tail stock vs a separate feed or hydraulic stop to stop is good
enough. Similar to an older James & Lamason which had a v and flat open way machine,
amenable to mounting both an auxiliary slide, and a traveling steady rest.

Do you know how long of a bar feeder you want ? I'm not sure I want one. Depends on stock length but with the low inertia of wood a containment tube

may do it.

Are the blanks already round ? Yes

You want 3 1/2 or larger spindle hole correct ? I will not be exceeding 3.125" Dia. to be fed and clamped.

You want live tooling and sub spindle too correct ? J&L for example sold a steady rest which clamped to both ways and stock from the same hydraulic

feed. On the J&L setup we used the CNC feed to "bump" the steady rest to the desired axial position prior to clamping........or, in this application if I save

cycle, it can be advanced and withdrawn to stops with a hydraulic cylinder. That's an add on we would fabricate. We also may have to fabricate an auxiliary

slide to plunge the form close to the spindle face. The lathe, if it isn't so equipped out of the box, just has to have suitable real estate secure such a feed

Screw machines can be had cheap and will do this if you are doing long part runs.
