Accessory apparatus for grinding machine that is utilized for polishing glass e.g. lens, has pump pumping collected water so as to circulate collected water through filtering device for removing residues obtained from grinding of glass

摘要

The apparatus has a wastewater drip tray (3) for collecting cooling water of a grinding machine through a primary filter (2). A pump (4) pumps the collected water so as to circulate the collected water through a filtering device (6) for removing polluting particles such as residues obtained from grinding of a glass, where the filtering device includes a replaceable filter cartridge (7). A recirculating pipe (11) recirculates the purified water by using the power supply of the grinding machine.
