The facility is an exhibition facility or test facility in an absolutely new condition. The plant was built in 2024 for the filtration of cooling lubricants in tool grinding: oil + carbide. Filtration is carried out with the help of 61 filter cartridges located in a cylinder housing. The dirty oil is pressed through the filter surface and runs through the inside of the filter into the clean container. The filter works in fully automatic mode. The filter pressure is monitored during the filtration process and as soon as the filter cake has been formed and the pressure increases, the filter is backwashed with compressed air. Then the filtration process starts all over again. The filtration system can be directly connected to the grinding machine, lapping machine, honing machine, etc. Filtration is carried out without consumables, as the filter is backwashed (filter flow, etc.).

The used coolant cleaning system based on centrifuge is connected to a tool grinding machine (Anca, Rollomatic, Walter, Schneeberger, etc.) and supplies the grinding machine with clean emulsion or clean oil. The pure oil is pumped directly to the grinding machine by pumps placed on the coolant cleaning system. Advantages of this system: 1. Use with oil or emulsion no problem 2. Filtration without consumables with the centrifuge, 3. Use with tungsten carbide, ceramic or HSS no problem. 4. The sludge comes out of the centrifuge dry, with minimal residual moisture. Pump capacity of supply pump 1 (for process supply): up to 80 litres/min. at 5-7 bar Supply pump 2 (for spindle cooling) 20 litres/min. at 5 bar The contaminated oil runs back from the machine into the filtration system and is cleaned in the centrifuge. Stage 1: Filtration by a centrifuge, without consumables, th ...
