The Pm-1440gt Has Landed

[QUOTE="One of the great things about the Hitachi is the amount of support there is on this forum.

Do you have the settings for the Hitachi VFD documented?
 
MKSJ on this forum did the wiring schematic and VFD parameters for me. I changed the wiring some but used most of the VFD settings. See attached.

I just ordered a PM-1440GT 3Phase and will be adding a VFD - I really appreciate the documentation you have posted up on here - it will be a lot less work for me :) . Just wondering where you picked up your electronics enclosure. I checked Wiegmann and the closest they make is 24x20x8 . yours looks like it fits the base perfectly. Do you know the manufacture?
 
Congrats on the new lathe. I'm glad you fine the information useful.

The enclosure is a Hubbel-Weigman N412241608C. Automation Direct or Zoro has them. I got mine from Zoro using a 25% off coupon.
 
Jay,

I too have a new 1440GT, and I will post pics soon.

I’m building a spider. What size tipped bolts did you use?

Congrats on the new lathe. Spider screws are 7/16" with 1/4" brass tips. I plan on up-sizing to 1/2" with 3/8' brass tips.
 
Jay, have you added a 6-jaw chuck to the 1440, any suggestions?
Not yet. It's on my list to do at some point. I could have used one a couple of times recently. The cost has kept me at bay since it would only be used occasionally. My 8" 3-Jaw adjustable is my go to chuck and gets used 95% of the time. Since picking up an ER-40 collet block and set of collets I don't use my 5C chuck as much any more. Just pop it in the 3-jaw, adjust and go.

A lot of people rave about the PBA Setrite chucks. Made in the UK, steel body. I could not find the minimum clamping dia. An 8" adjustable w/back plate will run $1650 plus shipping. The negative for me is it is a one pinion design which is a deal breaker. I have a 6 inch 3-jaw adjustable I used on my old lathe that I converted to run on the PM-1440 since it has a specific use. It is a 1-pinion design and it drives me nuts chasing the pinion every time it stops. Personal problem, probably doesn't bother most.

The Toolmex Set-Tru looks real promising. Made in Poland, 3-pinion, forged steel, 0.315" min clamping dia. w/back plate $1,270 plus shipping

On the budget end the Shars Zero-Adjust looks decent, Made in China, cast iron, 3-pinion design, 0.197" min clamping dia (maybe). w/back plate $795 plus shipping. The only thing I would confirm is that the scroll is hardened. The pinions are so I would guess the scroll is but it does not say on the website or the catalog. If not then that's out.
 
Personal problem, probably doesn't bother most.

Nope, doesn't bother me at all, (sorry Jay, just couldn't resist...). ;) :D

FYI, the TMX 5c chuck I recently acquired required a bit of tuning to get it to where I was satisfied. The PBX truly was a drop on fit. And the accuracy is unreal. But...it only as one pinion.

Once trued up, my TMX runs fine. It is definitely a step up from the offerings from the other side of the world.
