Marposs Tool Setter accuracy

[behindpropeller]

I ran a bunch of tools on our marposs toolsetter last night.

Length measuring is coming out to be +/-.0001

When having it measure the diameter of a tool I am getting +/-.020+

I'm taking some gauge pins home this evening to re-calibrate it but wanted to ask if there were any settings I should check??

Thanks

I don't know what it is but something is wrong. Call Haas or Call Marposs.

I will after I re-calibrate it. The biggest problem is that everybody at haas seems to know nothing about the marposs equipment.

Although my laser is on an okuma vmc, I am having the same issue you are; no one seems to know anything about them. I have yet to be able to find any osp programs/subprograms that will check tool diameter. I keep getting told that "no one uses the laser to check diameter", which blows my mind. I would love to get my hands on information about programming the damn thing, all I have been able to find is an installation manual.

Have you inspected the laser to make sure its tightened down to the table? The air pressure from the laser blower could be shifting it when it checks the cutters.
Also, is it possible that your tool holders or spindle chuck cavity has wear or damage and is giving you runout?
Lastly, have you tried hand indicating the cutters when they're in the spindle to check run-out and diameter. For fussy jobs, I usually indicate every tool in the spindle rite off the bat. I rarely have been over .0004.

UH, the post is over 2 1/2 years old, I'm guessing that it has been resolved.

Actually, it has not. I just have not had the time to mess with it.

well sence its still going,
make sure the pad is tight and square, then do all your calibration.
those pads come loose every once in a while. use a heigth gage and get it within .0001 flatness.

???WOW!!!!

Fix that thing already! Doesn't take long to tram the Renishaw one and calibrate it - maybe 30 minutes at most!

I have run the calibration program a few times. The problem with my marposs is that the diameter seems to never be correct.

I only use my machine for short runs and prototypes. I'm not a job shop running 100s of jobs per week.

is it giving you diameter errors when you check the tool that you use for the calibration program?
If so have you tried checking the reference tool for any type of run out? It is possible that that tool got bumped and is off, there-for screwing up your calibration, furthermore screwing up everything afterwords.
Its a long shot but an easy fix if that's whats going on.

You could also try indicating the laser itself to make sure its still square and hasn't been moved at all. If it was bumped at all then it wont be lined up with the work offset in the calibration and gauging programs.

The last time I set it up I checked the diameter and runout with a friends presetter.

Like I said.... Don't have a lot of time to mess with it and there is no section on troubleshooting it.

Seems to be some confusion here whether it's a laser type or probe type. Laser types can have issues with tool diameter for sure.
