Maintenance-free coolant tanks

Good machining requires good coolant management to maintain proper cutting zone temperature, lubrication, and chip removal. However, filtering and removing particulates in coolant that effectively become little bullets jetting through the machining system and disrupting the process can require extensive screening, expensive coolant flushes, and laborious tank cleanings. Until now.

To reduce machine downtime, Jorgensen Conveyor and Filtration Solutions developed PermaClean which eliminates sludge buildup by adding agitation to the coolant collection system or holding tank, preventing particulates from settling. Its continuous swirling of coolant keeps particles suspended through the filtration process until virtual elimination, reducing downtime to remove sludge or needing a sump sucker to remove particulates from the holding tank. The PermaClean solution add-on works in conjunction with Jorgensen’s base coolant systems such as:

• EcoFilter Conveyor – Filters fine particulates, they exit to the bottom of a conveyor, are scraped up and around to the top run of conveyor belt, then discharged
• FlexFiltration – Combines pre- engineered adaptable modules, filters difficult materials down to 10µm or less
• FilterVeyor Permanent Media Filter – Gravity drum with permanent media filter screens particulates, chips to clean coolant for reuse, recycling

Depending upon its properties, coolant can be cleaned to 10µm or less with the addition of a second-level filtration process. Bag filters provide the lowest filtration solution and can be integrated into existing systems. Gravity roll media filters using disposable cloth media are mountable to existing coolant tanks with the PermaClean solution to remove fine chips and grinding sludge. A hydrocyclone filter eliminating filter media consumption can also be used with the PermaClean system. In addition to its agitation-induced particle suspension, cyclonic filtration uses high-velocity flow through a conical whirl chamber employing centrifugal separation, throwing solids against chamber walls, and discharging through a nozzle at the bottom so clean coolant is ejected through a reverse vortex.

PermaClean also keeps machine tools running longer. Abrasive post-process particulates passing through the machining process and coolant circuit cause advanced wear on pumps, hose connections, and the interior of the machine tool. Removing most harsh elements reduces machine tool wear and extends tool life, delivering further cost savings. Likewise for part quality, clean, contaminate-free coolant is required for optimal part surface finishes and a reduction of potential scrap. Manufacturers can also realize cost savings by increasing coolant life. Extending coolant life will also become significant in the industry’s move toward more sustainable production.

For a fully automated, maintenance-free cooling circuit, manufacturers can pair PermaClean with Will-Fill automated coolant management technology – available through Jorgensen’s recent partnership with the Belgian company.

Clean coolant is key to extended tool life, reduced machine wear, improved part finishes, and less downtime.
