Chip Disposal and Coolant Cleaning Systems

Mayfran International’s magnetic chip conveyor and coolant filtration system for cast iron applications called the MagSep Conveyor, is for dedicated cast iron applications, and achieves a rapid payback in both machine uptime and reduced coolant maintenance costs, according to the company. When cast iron is machined, it creates fine particles in the range of 25 microns, which can quickly become suspended in the coolant to create sludge.

Mayfran International’s magnetic chip conveyor and coolant filtration system for cast iron applications called the MagSep Conveyor, is for dedicated cast iron applications, and achieves a rapid payback in both machine uptime and reduced coolant maintenance costs, according to the company.

When cast iron is machined, it creates fine particles in the range of 25 microns, which can quickly become suspended in the coolant to create sludge. Chips and fines can block distribution channels including pumps, reducing coolant flow to tools causing premature tool wear, inaccurate tool compensations, and higher heat that can work harden areas of the part plus increase fluid evaporation.

The system features a magnetic drag (or scraper) conveyor where coolant and chips are directed to the magnetic surface before exiting the conveyor. The magnetic bottom pan attracts ferrous chips and fines, and the conveyor flights continually remove chips from the bottom pan while clean coolant exits the tank. This action results in coolant clean enough for many machining operations at moderate costs.

For applications such as high pressure coolant that require removing fines and maintaining a 10 to 15 nominal micron level in the coolant, a AT-Cleaner can be added. The cleaner is maintenance-free, requiring no media filters to change and dispose of, resulting in lower costs and more spindle uptime. An easy-to-clean holding tank, separate from the clean tank reservoir, accumulates the sludge deposits discharged by the unit.
