Mori NL2500

[David Czerw Triumph Gear Systems]

Just ran a new prg on our NL2500. I don't have a post for this lathe yet. I'm not asking for one. I was wondering why the contour looks so choppy. This is the 1st time we are using live tooling to do a simple contour shape with an endmill around the flange of a part. The program ran good but the finish sucks. Just trying to keep the simple stuff off the mills. The manuals from Japan are tough to interpret, that's why I thought I would ask here. I'm only using the "X" and "C" axis.

Well, that could be many factors. I have had bearing failures in the live tool heads and when the bearings go, the finish will be as you describe. However, you will be able to hear bad bearings. Run the live tool head and if it dooes not sound smooth, then the bearings are cooked. If you need to replace them, email me and I can give you some info. I did one head myself and it's not difficult but is does take a while to break in the grease.

[Hardmill]

"C" axis contour has always given me beautiful

results on this machine.

Look at your geometry. Make sure all your filters

are on. What does the code look like ??

 

Ive only posted with Esprit but that shouldnt

matter as long as your geo is good.

Are you running it with G112 or just raw c/x output?

 

Mike

[David Czerw Triumph Gear Systems]

Raw c/x output. I was looking at the G112. It says something about "C" in mm not degrees?

[GoetzInd]

If you are you mplmaster, set misc value 4 to 1. That will give you good G112 code and not a million little Xc moves that give you that faceted finish you don't want.

We're going to take out the cutter comp and see if that helps.

Here is the last pass from the prg.

I would be looking here to smooth it out. Post it like this and give it a try. I would be surprised if it converts anything to metric.

[David Czerw Triumph Gear Systems]

Thanks Mike. That did it.

Thanks all for looking into this.
