Ah, in that case, don't use BOX_AXES. Also, don't use the automatic
labels in MAP_GRID. Draw the labels yourself with XYOUTS. (I also find
that for cylindrical equidistant projections I need to draw the
parallels and meridians myself (i.e., don't call MAP_GRID).)
Unfortunately, you have to set things up specifically for each map
projection that you use.
Something like this should get you started (dx and dy are fudge factors
to get the label alignment right). This example is for a cylindrical
equidistant global map.

I have almost a thousand compositions to be done. I need some
automactical procedure using map_grid and box_axes, or anything
simlilar :-I
Any suggsetions welcome

My advice is to just accept that IDL does almost-publication-quality
graphics. ;-)
Open the Postscript file in Illustrator and fix all the things you don't
like.
