Complete CNC Lathe Alignment - Part 3 - Spindle

[@devinpeck101]

This videos has been gold. I believe my Okuma has the same head stock to bed orientation as this machine. I’m glad I stumbled on this video I’ve been chasing center line alignment for a few days. Time to go try this!

I have done many lathes like this and have been to the Romi factory in Brazil. They actually have an amazing facility and I think that their Engineers are pretty ok too. The best way to tram a head in like this is to use a test bar in the chuck. Get it aligned with the Z axis plane. Then, using two tenth indicators mounted to the headstock near the adjusting bolts, move the headstock back or forth to align the turret centerline. Then take a test cut and make minor adjustments from there. An acceptable taper should only be about .0005” in 6.0000”. The Hardinge Quest line has the same setup where the X axis is on a slant but the head is not. It’s a little work but by making the machine like this, alignments can be made perfect for very precision parts. This machine that you were working on was a collaboration between Romi of Brazil and Bridgeport. Good job, nice video.

Thank´s Wes Johnson for the excellent tips you sou meticulously showed all interested viewers on this video. I just hope i don´t forget.

In my point of view, I would first start by checking spindle play and runout because if some of the bearings are going bad you will never get proper concentricity and your final part finish ajnd dimensions will suffer, Then I would follow by mounting a test bar in the spindle and go for the head stock alignment to verify if there is any taper. As for the tail stock, I think it is better to be able to align the whole bed like it is the case for this machine because every point of travel of the tail stock will drive parallel to the spindle axis, not just at a set distance wich would be the case if only adjusting the tail stock like we normally find on a regular manual engine lathe. Great series indeed! I did learn quite a bit here. Thanks for posting Wes.

From where i sit you did a great job Wes, thanks for sharing your time while doing this time consuming job. I have to do this on a Mazak QT when i have the time too. It is not running as yet, it is a project that i am working on when i have the limited time. But it will be great to have it back in one piece and running again. Regards Peter.

Wow a nice explain video ,thanks for sharing this to us on a simple way and save as all the time is need it to understand some of this machine . thank a lot

[@jarisipilainen3875]

28:45 yes there is tapered pins on tool turrent it move Y axis center. now you moved everything else

[@davidklainer9218]

Thank you Definitely helped. Very helpful man

[@coreyb4073]

i think my tsugami m08sy is similar with the head stock and z ways being flat, but the x is on an incline. but i have y axis to comp out centerline

[@jsa9767]

You are a real pro. Thank you very much.

[@davidclapham1066]

Excellent video series - good maths, or math as you fellows say :-)

[@1AB09CC3]

Wouldn't it be better to first test for taper turning (maybe without turning but just by sweeping the spindle nose) and adjust it and then check for the center height? I don't want to sound like smartypants especially as I never adjusted a head stock myself - I'm just curious :) EDIT: Maybe I should stop commenting before watching the whole video as I just saw you were not moving the center line but the angle of the head stock :D

[@cncit]

Is it audio noise or are the spindle bearings shot..I would usually check for play in the slide ways before doing the alignment...

[@WatchWesWork]

It's a gear drive spindle, so it's kind of noisy. There is nothing wrong with it though.

[@jarisipilainen3875]

4.06 spindle is allready factory centre. it wont move? opentool changer and change tapered pins claen and drill new if must. it been crashed and out allingment

[@jarisipilainen3875]

24:41 every new machines are done like that. align axis. chuck is bolted machine wall. how move center line LOL

[@rolandjollivet38]

Great video.. When you had the lined up the spindle, at 21.00 , do you store the X value as a machine variable?

[@jensjordan89]

Great videos! Thank you!

[@jarisipilainen3875]

15:57 good luck it will move. it was allready factory alligment

[@scottlundy257]

can you adjust for taper using software in the program ?

[@WatchWesWork]

Yes you can, but it's better to have the machine aligned properly. We want to put our best foot forward.

[@WCGwkf]

Scott Lundy ypu can but compensating for machine wear or misalignment always leads to more peoblems

[@clarencewiles963]

Thumbs up 👍 not hard but have skills

[@mannycalavera121]

Haas is another machine brand that's all on shims

[@ChunYun-hh8kl]

Head stock bearing is shot...

[@Srcannibalbmw]

Pues lo siento mucho, pero te falta mucho para dejar ese torno correctamente

[@milananojcic1863]

Sir I need help with spindle alignment...can I get your email? Or have I can contact you?

[@anduzavate2885]

This is so wrong and bad allignment,the way is way different.I would never do this way .

[@mannycalavera121]

Post your video then
