Hi,
I plan to create vertical gang lathe.
Total length will be 800mm
Linear slide by HIWIN 15mm with AC Servo motor.
Ballscrew dia 15mm pitch 5mm
Headstock 3-jaw chuck will be 3"
Spindle speed 5000rpm
I already start 1 week ago, by turning & grinding the headstock spindle.
Here I do Internal turning.

Finish Spindle, next week do drilling

I plan to create vertical gang lathe.

I will follow your thread with interest, Monkey King. "Gang lathe" is something that gets my attention. And that is an impressive boring bar you have too.

[Enraged]

looks very nice. did you cast the headstock, or bore it to that size?

[Monkey King]

The headstock made by cast iron, boring and finish by grinding.

Today I do the bottom of Z body.
See the picture, total length is 800 mm, weight about 120kg.

That's some fine turning you've done there Monkey King! I can tell you enjoy doing it. I predict that your new lathe will be a work of art.

Take care,
Paul

Here is the middle parts between z axis & x axis.
as size reference, 1 ceramic tile = 30 cm.

Size estimation of the gang lathe.

[RotarySMP]

Wow, that is a serious lump of metal you have there.

Nice design.

[Monkey King]

Today I finish the Z Body.

[RotarySMP]

Nice work. What mill are you using to make this?

[Monkey King]

Hi Mark,
I use cnc kneemill.

[Monkey King]

Here another view of Z Body.

[RotarySMP]

Nice toys you have there.

[Monkey King]

Today I drill the bolt hole for lathe spindle. Must be precise to maintain the balance.



Also I grind the middle parts between z axis & x axis.

[Monkey King]

I've done many thing here.
Made the insert to stop the linear rail.



Bearing stopper with grove for oil way.


Holder for servo motor


Ring between bearings.

[BobWarfield]

Very nice work!

What bearings will you use on your spindle?

Best,

BW

[Monkey King]

Hi Bob Warfield,
I'll use SKF 30310 J2/Q as back bearing and SKF 32212 J2/Q as front bearing.
