Portable Coolant Recycling System Runs During Machining
Westec 2017: The Eriez SumpDoc is an all-in-one portable fluid recycling system designed to completely filter and rejuvenate metalworking fluids in a machine tool sump without interrupting production.
The Eriez SumpDoc is an all-in-one portable fluid recycling system designed to completely filter and rejuvenate metalworking fluids in a machine tool sump without interrupting production. The system enables shop personnel to position the unit alongside the machine tool sump and treat the existing coolant while continuing to operate the machine tool.
The portable system consists of hoses, piping and valves to draw the coolant from sump, filter it and return it to the sump to create “scrubbing” turbulence; a continuous-flow tramp oil coalesce; a high-speed centrifuge for removing emulsified oils; a pleated bag filter for removing solids; an air-operated diaphragm pump to draw coolant from sump and pump it through system; a coolant make-up system with proportioner and onboard coolant concentrate tank; simple electrical controls with operator dashboard; five-gallon onboard containers for tramp oil, centrifuge backwash and coolant concentrate/chemical storage; a Microzone generator for microbiological treatment; and a 110-V single-phase control voltage.
Precision Tool Technologies found capacity for diversification not by adding machines, people or space, but by freeing up time. Running unattended—running so it can machine through all 168 hours in the week—has enabled this shop to use hours when staff is present to deliver work that lands outside its established specialty. To achieve unattended machining, some of the biggest challenges have related to basic details such as chips and coolant.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
Consider design differences when determining what style of mist collector is best for a given application.
