Pneumatic cylinders are frequently used both to clamp the workpiece into the fixture, establishing electrical contact, and also to index electrodes into internal workpiece features. The workpiece is connected to the positive side of the power supply and becomes an anode. Masks are made from nonconductive electrochemical deburring process pdf download and are bored out to cover the electrode except in the work zone, plus additional space for the flow of electrolyte.

An ECD workstation consists of a frame mounted sink, an electrolyte tank and pumping system, and a DC power supply. The gap between the electrode and the workpiece at the work zone is electrochemical deburring process pdf download 0. Electrolyte flow is provided by a stainless steel centrifugal pump to a manifold mounted to the frame behind the back electrochemical deburring process pdf download flowrates to fixtures are set by individual needle valves. All production ECD machines require an electrolyte filtration system with its own pump; bag filters, filter presses, and, for ultimate electrolyte cleanliness, nanofiltration membrane filters are used.

Fixtures An ECD fixture starts with a base made from a conductive material onto which a workpiece is mounted and precisely located. Customized Solutions We can work with you to produce a controlled manufacturing solution that fits your needs, whether it is for Abrasive Flow Machining or Electrochemical Deburring.

ECD removes metal by non-coontact, electrochemical action, with is fast, highly-selective, and safe. With good filtration, maintaining the correct salt concentration, and pH adjustment, a batch of electrolyte can be used for several months before it needs to be replaced.

Backsplashes are located at the rear and sides of the sink. For most applications, we recommend an electrolyte made with 2 pounds of sodium nitrate per gallon of water.

Electrolytic Deburring, also known as Electro Chemical Deburring ECD is a highly productive, precision technology for deburring and radiusing edges, especially at the intersections of dodnload passages, or other difficult to access features of a workpiece.

Tool design centers around the mask and the electrode. Process ECD removes metal by non-coontact, electrochemical action, with is fast, highly-selective, and safe. Electrolyte The electrolyte is a simple conductive solution of a salt dissolved in water. The most common electrolytes use sodium chloride or sodium nitrate as the salt.

Machines An ECD workstation consists of a frame mounted sink, an electrolyte tank and deburrin system, and a DC power supply. Power supply cooling can be either pocess forced air or cooled water.

Busbars for electrical current, manifolds for electrolyte, compressed air, electrochemical deburring process pdf download rinse water are mounted onto the backsplash for convenient access. With electrochemical deburring process pdf download electrodes, multiple intersections can be simultaneously deburred. Some metals, such as titanium, require blends of several salts to achieve the best results.

Electrochemical Deburring Systems

An electrode may be mounted stationary onto the base such that it is correctly positioned relative to electrochemical deburring process pdf download feature being deburred when the part is mounted onto the fixture, or electrodes may be mounted on pneumatically actuated slides and positioned inside the workpiece after it has been located onto the base.

Elecrochemical output can be provided down to 50 millisecond pulse width. The piece is then placed onto a fixture, and is connected to the positive side of the power supply, becoming an anode. In a frequent application: The workpiece is rinsed with water, or with a rust inhibitor electrochemical deburring process pdf download for mild steel workpieces. Electrolyte is flowed through the workpiece and current is turned on for 10 to 30 seconds.

Electrolyte is flowed through the workpiece, while the current is turned on for 10 — 30 seconds.

An ECD fixture starts with a base made from a conductive material onto which a workpiece is mounted and precisely located. Because of the placement of the cathode into the workpiece, the burred edges of the intersecting holes are closest to the conductive tip of the electrode; metal removal is thus focussed at these edges which are quickly deburred and radiused.

The electrode is insulated except at its tip, which is precisely placed at the intersection of the two holes. The mask can also serve as a locating device for the workpiece. However, unlike plating, during electrolytic deburring the metal which is removed is converted into fine metal hydroxide particles, which are flushed out of the part by the electrolyte, and can be removed from the procesd with filtration.

The electrolyte is a simple conductive solution dpf a salt dissolved in water. At the end of the cycle, the current is turned off, electrolyte flow stops, electrochemical deburring process pdf download the part is removed from the downolad and simply rinsed with water or with a rust inhibitor solution for mild steel workpieces. We can work with you to produce a controlled manufacturing solution that fits your needs, whether it is for Abrasive Flow Machining or Electrochemical Deburring.

A worktable to flectrochemical fixtures is mounted in the sink. The electrolyte tank is separated by an internal divider deburirng two compartments for clean and dirty electrolyte sits under the frame, and has a capacity of approximately 60 gallons. With multiple electrodes, multiple electrochemical deburring process pdf download in a workpiece can be simultaneously deburred.

The process involves three principle elements: At the end of the cycle, the current is turned off, electrolyte flow stops, and electrochemical deburring process pdf download part is dowhload from the fixture.
