the chips flushed with the polishing liquid fall into the water tank 71, fall into the filtering mechanism 82 through the return pipe 81 together with the polishing liquid, are filtered by the filtering mechanism 82 and then fall into the water tank 74 for continuous use, so that the polishing liquid can be recycled, and the consumption of the polishing liquid is reduced.

The mixture of debris and grinding fluid falls through return conduit 81 into screen 822, where the debris is filtered by screen 822, resulting in cleaner grinding fluid flowing into tank 74.

When the filter screen 822 is heavily soiled, the filter mechanism 82 can be removed and the return tube 81 and rubber ring 825 can be pulled out to dump the soiled debris through the connector sleeve 824.

Then through inserting a section of thick bamboo 821 in mounting hole 83, carry out spacingly through collar 823, the rethread rubber ring 825 carries out the connection of back flow 81 with the cooperation of adapter sleeve 824, can polish the filtration of liquid again.
