Electrical Discharge Machining

Doctor Uses Machine Treatment For Depression

Since December, Dr. Michael Saribalas has treated 50 patients.

Karynda Kearns tried counseling and medicine with mixed results, until she went to Saribalas for therapy. He used transcranial magnetic stimulation, or TMS.

SPECIAL SECTION: Health

It is a drug-free machine treatment, based on a scientist's discovery nearly 200 years ago.

The treatment lasts around 30 minutes daily, for three to four weeks. The FDA has cleared TMS for patients who have not been helped by at least one anti-depressant. 

"If you turn a magnetic field on repetitively, on and off, on and off, it would create an electrical discharge," Saribalas, said.

That discharge applied to one area of the brain, stimulates it to release certain chemicals.

"Usually that improves your mood. So not as depressed, appetite gets better, sleep gets better. People become energized, Saribalas said.

"I started having hope again," said Kearns. "That was nice because not even medication can work that quickly."

Saribalas said up to 70 percent of his patients who have tried this treatment have been helped.

He said TMS has been in clinical trials to see if it also can help people with Parkinson's Disease and migraines.

Intricate Machining Designs with EDM Technology : : blog ...

A desired shape of the work piece is obtained through electrical discharges or sparks and that mechanical process is called electric discharge machining or EDM. Series of fast recurring current charges between two electrodes (separated by a dielectric liquid) and subject to electric voltage removes the material from the wok piece. The parts of electrode are the tool electrode and work piece electrode.

There are three types of EDM, namely sinker EDM, wire EDM , and small hole EDM Header Dies . Sinker EDM machining uses spark erosion to machine blind cavities. This process employs machined electrodes that produce sparks along the surface of the electrode to sink or plunge the cavity. The Sinker EDM process is ideal for a number of applications: Blind Cavities, Intricate Details, Sharp Corners, Fine Finishes (Surface Finishes to 10 Micro-Inch), Thin Walls and Cross Sections, Machining Threads into Hardened Parts, Blind Keyways, Internal Splines, Squares, or Hexes, Tolerances can be held to .0001″, Any conductive material can be Sinker EDM machined, including Aluminum, Brass, Carbide, Copper, Hastalloy, Inconel, Steel, Stellite, and Titanium. Wire EDM-also known as Wire Cutting, Wire burning, and Traveling Wire EDM-uses spark erosion to machine or remove material with a traveling wire electrode from any electrically conductive material.

The wire electrode usually consists of brass or zinc-coated brass material. It is applicable to the following: Machined Parts, Tool & Dies (such as Steel and Carbide Dies used for steel wire drawing), Gauges and Fixtures, Mold Components, Prototypes, Production, Exotic Materials. Small Hole EDM drilling uses the same spark erosion principle as Sinker or Ram EDM. Small Hole EDM drilling is ideal for putting ejector holes in hardened punches, coolant holes in cutting tools, vent holes in molds, and start holes for Wire EDM.

The advantages of Cold Forming Tooling includes: Complex shapes that would otherwise be difficult to produce with conventional cutting tools, extremely hard material to very close tolerances, very small work pieces where conventional cutting tools may damage the part from excess cutting tool pressure, there is no direct contact between tool and work piece. Therefore delicate sections and weak materials can be machined without any distortion.
