Use a screwdriver to unscrew the four screws connecting the base and the micro seat from the bottom surface of the metallographic microscope base, that is, the micro seat (including lifting drive group, micro gear group and other components) can be removed from the base. But pay attention to protect the bottom of the micro seat, do not collide, knock or scrape, not to mention grinding on the sandpaper.

It must be pointed out that when maintaining the metallographic microscope, it is not necessary to disassemble the whole metallographic microscope into parts according to the above steps, but the parts that need to be repaired can be disassembled selectively according to the specific situation.

When the repaired parts are put back into the metallographic microscope, the parts should be installed in the reverse order of the disassembly procedure. That is to say, the first assembly should be dismantled, the first assembly should be dismantled. Do the same when assembling parts into parts, otherwise it will result in repeated assembly and disassembly, a waste of time, missing parts and increased chances of damage. When installing the metallographic microscope, attention should also be paid to the interconnection points of the parts and components. When tightening the screws, attention should be paid to whether the size of the screwdriver is appropriate and the force should be uniform.

If it is a number of screws together to tighten a part, we should pay attention not to screw a screw too tight, and in a certain order to cross all the screws tightened to the same degree, and before tightening the screws, pay attention to the position of the parts to adjust, and then one by one all the screws tightened.
