Hi all,
I've got a question regarding Renishaw probing.
We've bought a new Hurco VM10i since a month with the complete probing package (TS27R and OMP60)
There we're allot of issues with installation and some issue are still present, due to a lack of knowledge from the service guy. Total disaster.
I shall only tell the issues regarding probing, since that's where this topic is about. And otherwise the list will become too long.
- renishaw workprobe stylus not adjusted so it had 0,03mm (0.118")runout.
- toolprobe was not aligned on the table
This was fixed today by a different service guy.
But there are still issues.
When checking diameter with a pin gauge in a collet the measurements are not consistent.
When repeating the diameter probing the maximum difference between measurements was 0,08mm (0.315")
That's huge!
When adjusting the probing speed he could reduce the difference to within 0,02mm (0.08)
And sometimes it gives an error about the max spread is exceeded.
According to the Renishaw manual it should repeat to 0,001mm (micron) -
Above measurements done with the pin gauge not rotating.
When using an endmill or facemill and rotating it, the numbers are way! not usable.
So all this was done with the tools not rotating.
I highly doubt this is correct. And the service guy is trying to let me think this is normal.
He says non of their customers use it the way how I want to use it (rotating a cutter and measuring the tool by length and diameter)
And they only use it to check for length and broken tool detection. He called Hurco Germany and they said it was normal. Wtf? why spend 10.000 Euro on a probing package. Even my digital caliper is giving more consistent results.
He also says the readings vary because of the machine is hot.
It's been sitting idle all day and did only 20 probing cycles...total bs
Then he said it was due to machine accuracy.
That the toolsetter could repeat in a micron doesn't mean the machine can.
True...but I'm sure the machine is accurate enough to repeat within 0,02mm / 0.078"
And that wouldn't explain the variations between readings. And the slight decrease in variations when using a lower probe feed.
So I'm checking if I'm going crazy or have a mechanic that doesn't know how it works?
Why would you even probe diameter of the readings are way off and vary each time? Why would you want to update the tool wear like this?
We didn't checked the tool length yet.
But before the aligment of the TS27R there where also big variations in readings when the tool was rotating.
