Wire Electrical Discharge Machining (WEDM) belongs to the category of electrical machining. When the couple of the former Soviet Union Lazarenko studied the phenomenon and cause of damage to the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of electric spark can The local metal is melted, oxidized and corroded, thereby initiating and inventing the electric discharge machining method. The wire cutting machine was also invented in the former Soviet Union in 1960. China is the first country to be used for industrial production.
Distinguish between fast wire cutting, medium wire cutting and slow wire cutting. 1: The wire-traveling speed of the fast-wire EDM wire cutting is 6 ~ 12 mm / s, and the electrode wire performs high-speed reciprocating motion, and the cutting accuracy is poor. 2: Medium wire EDM wire cutting is a new technology developed in recent years that realizes the frequency conversion multiple cutting function on the basis of fast wire cutting. 3: The wire-traveling speed of the slow-wire EDM wire cutting is 0.2mm / s, and the electrode wire performs low-speed unidirectional movement, and the cutting accuracy is high.
WEDM is widely used in the application of high-precision parts such as mold parts, automobile parts, mechanical parts, medical parts, and motor parts.

New Electric Face at the 2009 Detroit Auto Show
At the start of this year, Toyota unveiled the FT-EV, an all-electric commuter concept car, at the Detroit International Auto Show. This compact vehicle was designed to offer a practical and eco-friendly option for city driving, with an estimated range of 50 miles on a single charge and seating for two passengers. The FT-EV shared some design similarities with the newly introduced Scion iQ, but it had a more rounded, organic look that many found more appealing than the iQ’s sharper, more aggressive styling. Additionally, the FT-EV featured a newly developed battery system that allowed it to reach a top speed of 70 mph.
On the official FT-EV website, Toyota emphasized its commitment to advancing technology and exploring various options for future mobility. This approach aligns with their broader strategy, which includes the continued development of hybrid vehicles like the new Prius. With the growing demand for electric and hybrid cars, Toyota is aiming to sell approximately one million hybrid vehicles annually by the next decade.
Another intriguing concept from Toyota, the "Detroit Toyota Mystery Concept," also made an appearance at the show. Although it's still just a concept, Toyota hinted that a production version could potentially hit the market as early as 2012.
So, why are automakers like Toyota investing so heavily in electric and hybrid vehicles? The answer lies in their vision for the future of transportation. Toyota believes that no single solution will work for everyone. Instead, they advocate for a variety of options—whether fully electric, hybrid, or even hydrogen-powered—to meet different consumer needs. By offering more choices, they hope to encourage more people to choose greener alternatives.
Looking ahead, the upcoming Detroit Auto Show promises to be another exciting event. Rumors suggest that Toyota may reveal another electric or hybrid compact car at the show. While details are still scarce, the company has already released some teasers to build anticipation. As the event approaches, more updates are expected, so stay tuned for the latest news.
