The recirculation system () may have an upper reservoir () configured to drain fluid into a lower reservoir () before recirculating the fluid. The upper reservoir () may have a standpipe () configured to allow swarf, debris, and/or other material within the fluid to be entrained prior to flowing over the standpipe ().

Standpipe recirculation systems for material removal machines

Apparatus and systems are disclosed of a splash guard for a grinder/polisher having a base, a bowl, and a platen having an outer edge to prevent splashing during the grinding/polishing operation. The splash guard includes an inner sidewall, a lower rib, and outer sidewall, and an upper rib. The lower rib has an inner edge that is spaced at least 2.5 centimeters from the outer edge of the platen to prevent pinching of an operator's hands between the platen and the splash guard. The splash guard may also include a recess formed by the upper rib, outer sidewall, and lower rib, and at least a portion of an inner edge of the upper rib is extending further inwardly towards that platen than the inner edge of the lower rib.
