Hi Carlos,
Your board may be bent but this problem is usually associated with the machine's table not being flat and true with the machine's motion.
It is usual to fit a 'spoil-board' to the machine table then 'surface' this board (with a reasonably large diameter cutter) to make it flat and true with the machine's motion. Thereafter your PCB's will have equal depth of engrave over the whole surface.
