Hello guys!
First of all, Merry Christmas to everyone!
My thread today is about the backlash.
I have a Kitamura mycenter 1xif, it's the model with high precision contouring control option for reference... Control is Fanuc 16i mb
Anyway,I have been spending money on this machine, I have got some of the Fanuc drives refurbished as well as spindle refurbished, and x-axis ballscrew refurbished.
Now the question is I checked the parameter 1851 (fanuc backlash parameter) before refurbishing the ballscrew was 330, after refitting ballscrew , value has been adjusted to 100.
Are those values in microns, 100 microns after refitting seems huge , I have seen a thread where a guy with a Kitamura HX400 said a value of 100 equals to 10-micron adjustment which would make sense then?
I have read another thread where a guy with a Fanuc 20i control with high-resolution encoders said when the machine was new, he had on the y axis value 65 which then would seem on average compared to the values set on my machine.
Then I do still have 0.0003" on the y-axis and 0.0004" on x and Z which I would like to compensate or sort out.
I only "checked" back with the tenth clock.
Thanks in advance!
