  1. Know About Electrical Discharge Machining | Parallel Ventures Welcome to Parallel Ventures Challenge the Limits of Precision

  2. About Us Parallel Ventures is a US-based highly specialized CNC milling Machine Company that challenges the limits of precision in manufacturing products for four major industries including Aeronautics, Military & Defense, commercial aviation, and electric vehicles. We believe in delivering high-standard quality products to the manufacturing processes with our advanced CNC machinery capabilities. We supply mission-critical parts with extremely tight tolerances.

  3. Know About Electrical Discharge Machining If you’re looking for a way to machine metal components with precision and accuracy, electrical discharge machining (EDM) might be the right process for you. This blog post will take a closer look at EDM, how it works, and some of its advantages. EDM is a process that uses an electric spark to remove material from a workpiece. The spark is generated by an electrode connected to a power source. As the electrode approaches the workpiece, the electric field between them creates an arc of electricity. This arc causes the material to be vaporized from the workpiece’s surface, forming a crater.

  4. The crater’s depth can be controlled by moving the electrode closer or further away from the work piece. Repeating this process makes it possible to create precise and intricate shapes in the metal. EDM can be used on various materials, including metals, alloys, and ceramics. It’s especially well-suited for machining hard or fragile materials that other methods, such as grinding, might damage. How does EDM work? The working principle of an EDM machine is relatively simple. An electrode is connected to a power source and brought close to the workpiece. As the electrode approaches, the electric field between them creates an arc of electricity. This arc causes the material to be vaporized from the workpiece’s surface, forming a crater.

  5. What are the different types of EDMs? There are three main types of EDMs. These are wire EDM, hole, and sinker EDM. Each type uses a different electrode to create the electrical discharge. 1. Wire EDM Wire EDM uses a thin wire as the electrode. This wire is fed through a guide tube and is constantly being consumed as it wears away. This type of EDM is best suited for cutting complex shapes in metal plates. 2. Hole EDM Hole EDM uses a cylindrical electrode to create holes in work pieces. The electrode is slowly fed into the workpiece while an electric current is passed through it. This process can be used to make blinds or through holes.

  6. Sinker EDM Sinker EDM, also known as plunging EDM, uses a tool shaped like the desired final product. This tool is slowly immersed into the workpiece while an electric current is passed through it. This process is best suited for making 3D shapes. Advantages of EDM process EDM offers several advantages over other machining processes. These include: 1. Precision EDM is capable of creating exact and intricate shapes. That is because the process can be controlled accurately, allowing minimal tolerances. 2. No tooling With EDM, costly and time-consuming tooling is no longer needed like other methods, such as stamping or casting. That makes it an attractive option for prototyping and low-volume production runs.

  7. No heat-affected zone Since there is no direct contact between the electrode and the workpiece, there is no risk of heat damage to the material. That makes EDM an ideal choice for machining heat-sensitive materials. 4. High quality EDM produces a high-quality surface finish with little or no burrs. That is because the material is vaporized rather than cut, so there is no risk of chip formation. 5. Fast EDM is a fast process that can produce parts quickly, even in high volumes. Bottom line EDM is a versatile and precise machining process that offers many advantages over other methods. EDM might be the right solution for you if you’re looking for a way to create complex shapes in metal with accuracy and precision.
