What is EDM gearbox?
A wire electrical discharge machine (EDM) cuts intricate two-dimensional patterns in steel plates, making it a viable method for producing prototypes and small quantities of parts such as spur gears. In this process, a fine brass or tungsten wire is threaded through a small hole in the steel plate.
What materials can you wire EDM?
What materials can be cut using EDM wire? Any conductive material such as steel, titanium, aluminium, brass, alloys and superalloys can be cut using the EDM wire method. With its accuracy, the EDM wire cut technique has become a convention cutting method in all industries.
What are wire EDM machines used for?
Wire EDM is most commonly used in mold and die manufacturing processes, particularly for extrusion dies and blanking punches. EDM can be used in everything from prototypes to full production runs, and is most often used to manufacture metal components and tools.
Can wire EDM cut plastic?
Virtually any material that is conductive is a perfect one for wire EDM, and it includes all the metals. DEK’s wire-cut EDM equipment also can machine plastic, metal alloys, exotic and precious metals.
What is EDM motor?
Electric discharge machining (EDM) cuts or shapes the workpiece using a metallic wire. This wire is often a conductive material, with a thin electrode wire that follows a precisely programmed path. A motor that can deliver the desired speed and tight control is an essential part of the EDM machining process.
What is EDM electric car?
BorgWarner Provides High-performance Electric Drive Module (eDM) for New Electric Vehicles from Great Wall Motors. Integrates electric motor with eGearDrive® transmission to offer high efficiency and a comfortable driving experience.
Why is brass used in EDM?
Brass wire Zinc has a lower melting/vaporization point which makes it a better electrode material than copper, so the more zinc in the surface of an EDM wire, the faster it will cut.
Is wire EDM a CNC machine?
Wire EDM uses CNC technology to control the wire’s path with unmatched precision—making it an ideal solution for the production of parts with precise dimensions and extremely high tolerances. Despite its strengths, wire EDM is not ideal for every machining project.
Can you EDM glass?
Another machining method for glass, which can be used for micro-hole drilling, is micro-electrical discharge machining (EDM) with an assisted electrode [89,90]. The EDM process is based on ablation of material through melting and evaporation, by electrical discharges.
What is a driving module?
The Drive module brings together several functions within a lightweight and high-strength aluminum structure. This is the basic body, complete with the suspension, crash element, energy storage device and drive unit.
How do you choose tool material for EDM?
Stainless steel as tool materials has found to better in terms of higher material removal rate and lower tool wear in EDM process.
Is EDM wire expensive?
EDM wire, at its current cost of approximately $6 a pound, is the single highest cost related to the use of WEDM technology. The faster a machine unspools wire, the more it costs to operate that machine.
Can you EDM tungsten?
Because tungsten is a very hard material, conventional machining is often difficult or impossible. We utilize Electrical Discharge Machining (EDM) to overcome this difficulty.
What is wrong with wire EDM machining helical gears?
The issue with Wire EDM machining helical gears is that the wire itself cannot produce or be bent to follow the proper radial rotational form. Even when machining with a 4-Axis program, the wire path can only produce the proper geometry at the very Top and Bottom of the helical gear.
What is wire EDM and why is it useful?
This is where wire EDM becomes extremely useful. With the help of wire EDM, you no longer need to hire anyone that uses other special cutting tools. That’s because wire EDM machines can cut any spur gear, and the accuracy is on point!
Can wire EDM cut spur gear?
That’s because wire EDM machines can cut any spur gear, and the accuracy is on point! Because of the speed and accuracy of wire EDM, you can expect that production times and costs, even if you’re still in the process of building a prototype or you’re making small production runs, will be much faster and more economical than other choices.
How long does it take to make a prototype with EDM?
But that’s not the case with EDM. Plus, prototyping is fast. For example, instead of the typical 8 week lead time to produce prototype metal gears using some technologies, with the help of wire EDM, the lead time can be shortened to 1 week.
