What is EDM? Electrical Discharge Machining (EDM) is a non-contact machining method that uses electrical energy to shape metal without the tool directly touching the workpiece. Unlike cutting, grinding, or polishing, EDM removes material through thermal energy generated by electrical discharges. Let’s explore the basic principles and advantages of EDM. What is Electrical Discharge? An…

In this first blog post of the year, we’ll explore one of the most essential components of electric vehicles — the drive motor, and its crucial relationship with lubricants used during manufacturing. What is a Drive Motor? A drive motor converts electric energy into mechanical power, enabling an EV to move. It works by delivering…

What is Electrical Discharge Machining (EDM)? Electrical Discharge Machining, commonly known as EDM, is a manufacturing process that removes material from a workpiece using electrical sparks generated between two electrodes — an anode and a cathode. These electrical sparks generate extremely high temperatures, which melt or vaporize the material, allowing for precise shaping of the…

In the world of metalworking, precision is everything. When it comes to producing highly accurate, clean-edged components with tight tolerances, fine blanking stamping emerges as a cutting-edge solution. But precision doesn’t come from machinery alone — it requires the perfect synergy of process, materials, and support systems. What is the One often-overlooked factor that plays…

What is Fine Blanking? Fine blanking is a high-precision metal stamping process developed in Switzerland in the 1920s. The term itself means “precise blanking,” referring to the process of punching out parts with extremely smooth and accurate edges using plastic deformation under high compressive stress, a phenomenon known as the hydrostatic pressure effect. This effect…

From phone charging cables and telephone communication lines to data cables connecting PCs to the internet, and various memory card modules in automotive navigation systems — connectors have long been the invisible enablers of our daily digital lives. Although wireless technology is advancing rapidly, we still face numerous technical challenges before everything can be fully…

Thanks to its unique properties, aluminum plays a critical role in various industries. Due to its lightweight and corrosion-resistant characteristics, aluminum is an essential material in industries such as automotive, electronics, and construction materials. However, in the process of aluminum fabrication, the punching process is key to improving the quality of the final product. And…

Punching oil is an industrial lubricant used for punching holes or forming shapes in metal. It is generally classified as a metal forming lubricant and is also known as punching oil. Applications Punching oil is widely used in the manufacturing processes of motor cores, heat exchangers for air conditioners and refrigerators, radiators for automobiles and…

Industrial lubricant market is already saturated with numerous manufacturers. However, punching oil, unlike general-purpose industrial lubricants, is mainly used by large-scale manufacturers and requires strict testing and qualification before being adopted into mass production processes. In particular, major corporations often demand formal approval processes and documentation, making entry into this market quite difficult. Due to…

When we think of metalworking industries, we often picture massive machines roaring as they cut, bend, and stamp red-hot metal. In all these intense processes, there’s a hidden but crucial player—punching oil (also known as stamping or press oil). At Dyna, we pride ourselves on our unmatched expertise in the field of punching oil. Our…
