The invention relates to a grinding process without glue removal, which comprises the following steps: using a quantitative dispensing machine to inject glue into ferrules, and controlling the amountof glue inserted into the ferrules to be consistent; using a cutter to strip optical fibers, and ensuring that the optical fibers are of the same length; putting the ferrules in a fixture side by side; passing the optical fibers through the ferrules and drying the ferrules; carrying out cutting by laser along the bottom ceramic surface of the fixture; and taking the ferrules down from the fixture,and grinding the end faces of the optical fibers with 1-micron sandpaper. Compared with the prior art, by using the grinding process without glue removal in the invention, glue removing and rough grinding for optical fiber jumpers are eliminated, the grinding process is reduced, the grinding efficiency is improved, and the production cost is lowered. Moreover, grinding water is saved, and water pollution is reduced.
