Filtration Device Manufacturer

Background:

The tubular wedge wire fabrication is manufactured from Stainless Steel, Inconel, or Hastaloy, as a family of parts ranging in size based upon application. The fabrication is constructed of a spiral wound band around a cluster of axial and uniformly aligned rod, forming a tubular structure. The cutoff process requires the cutting medium to pass through all of the structural components exposing many facets, all of which would be very difficult, from which to remove burrs.

Manufacturing Challenge:

Cut off short, accurate length sections from a long tubular structure, protect feature integrity, and minimize or eliminate burr generation. Previous cutoff process included fine pitch saw and abrasive blade cutoff. Fine pitch saw experienced very poor saw blade life and required secondary burr removal. Abrasive blade cutoff was responsible for robust burr generation and time consuming and costly burr removal.

Solution:

Everite Machine Products standard product offering includes an Electrochemical Tube Cutoff Machine. The Electrochemical Tube Cutoff Machine automatically advances the work for preset cutoff length and employs electrochemical technology for burr free cutting. The Everite Electrochemical Tube Cutoff Machine provided a simple means, addressing the full family of parts, for accurate, burr free cut to length filtration components. The parts were electrochemically cut effectively and efficiently, maintaining structural integrity, and completely eliminating burrs. Cost savings and productivity improvement, through elimination of secondary operation burr removal, provided the customer with very significant advantages.
