PRAB's Candle Filter is specifically engineered to meet the challenges of effectively removing fine particulate from spent oil in Honing and EDM machining applications and Tungsten carbide tool and steel ball grinding applications. This new filter uses a permanent media in a long cylinder that houses over 10,000 thin membrane wafers. These membranes effectively and consistently capture grinding swarf at 1µm. These dependable filters operate with virtually no downtime for maintenance. The self-cleaning, air driven backwash system automatically clears the filter of dirt and debris allowing the Candle Filter to perform reliably under long production runs.
• Engineered for oil filtration in EDM, tungsten carbide tool grinding, electrical discharge machine, honing machine, and bearing grinder applications.
• Permanent membrane wafers trap grinding swarf at 1-3µm.
• Automatic air pressure back flush cycle reduces labor costs and increases process efficiency.
• Swarf and oil is purged into an external receptacle for easy collection and recycle.
• Optional chiller ensures constant fluid temperature, varying only 1-3°F, to maximize tool life and part quality.
Related Glossary Terms
- electrical-discharge machining ( EDM)
electrical-discharge machining ( EDM)
Process that vaporizes conductive materials by controlled application of pulsed electrical current that flows between a workpiece and electrode (tool) in a dielectric fluid. Permits machining shapes to tight accuracies without the internal stresses conventional machining often generates. Useful in diemaking.
- 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.
- swarf
swarf
Metal fines and grinding wheel particles generated during grinding.
- tungsten carbide ( WC)
tungsten carbide ( WC)
Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
