Eriez HydroFlow manufactures an array of compact filter systems. The products in this line include Gravity Filter Systems, Magnetic Coolant Cleaners and Hydrocyclone Separators.
The Eriez HydroFlow Gravity Filter Systems product line refers to filters that use gravity to force dirty coolant through the filtration media. These systems are primarily used for industrial machine applications, but large flow cell type systems can be offered. Gravity Paper Systems employ disposable roll media for filtration and are ideal for grinding applications. Gravity Drum Systems employ a permanent stainless steel or nylon mesh filter media and are ideal for machining applications, particularly aluminum machining where floating chips are present. Standard units are designed with low coolant entry height, allowing for gravity return from the machine tool.
Eriez HydroFlow Coolant Cleaners keep machine tools running longer and more accurately with lower costs per unit produced. As stand-alone units or in conjunction with the Gravity Bed Filters, Magnetic Coolant Cleaners provide media free removal of ferrous contaminants down to 50µm.
Hydrocyclone Separators from Eriez HydroFlow are media free systems that use centrifugal force created by a feed pump to separate solids from liquids. Dirty coolant enters the cone through a vortex tube, which causes the coolant to swirl downward. The solids in the coolant are forced to the outside of the cone and exit through an underflow outlet at the bottom. Clean coolant flows back up through the vortex column and is discharged out the top of the cone.
Related Glossary Terms
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
