Sinker EDM machines run in oil, while wire EDM machines run in deionized water. Both use the same process, so why do they need different fluids? Both machines remove metal with electrical sparks between an electrode and the workpiece. The principle is the same, but the machining method, spark energy, gap size and debris flushing…

“Carving hard metals with lightning sparks instead of physical cutting blades?” Electrical Discharge Machining (EDM) is a fascinating, high-precision manufacturing method that uses thermal energy from electrical discharges rather than conventional mechanical cutting tools. From aerospace components and precision molds to medical devices, EDM is essential for processing hard-to-machine materials that cannot easily be cut…

Every manager operating a thermal fluid boiler in an industrial setting faces this deep dilemma at least once: “The oil level has gotten a bit low. Should I just top it up with new oil, or should I do a full replacement this time?” Replacing hundreds to thousands of liters of thermal fluid is a…

When you need to heat machinery or raw materials in an industrial setting, what method comes to mind? It is easy to think of “boiling water” or “steam,” but in precise industrial processes that require high temperatures, a special type of oil called “Thermal Oil” is used. In today’s post, we will clearly explain the…

In the heat treatment process, which determines the strength and lifespan of metal, the most dramatic moment is undoubtedly “Quenching.” This process, in which red-hot metal is plunged into a liquid to cool it down in an instant, is called the flower of metalworking. However, this raises a question: “Why can’t we just cool it…

The global wave of ESG (Environmental, Social, and Governance) management is rapidly changing the landscape of manufacturing sites. In the past, productivity and processing quality were the only top priorities, but now ‘eco-friendliness’ and ‘worker safety’ have become core indicators that determine the success or failure of factory operations. Amidst these changes, the most spotlighted…

Do you know the hidden contributor that determines the lifespan and yield of equipment in the semiconductor, display manufacturing, and industrial robotics sectors? It is none other than ‘Lubricating Grease’, which prevents component wear in extreme environments. However, industries have long struggled to find the perfect lubricant. Today, we will explore the necessity and innovative…

In the past, “low cost” was considered the ultimate virtue for EDM fluids on the mold machining floor. It was common practice to purchase them in bulk by the drum, use them until the oil turned pitch black and emitted a foul odor, and then dispose of them to refill with fresh oil. This role…

Hello! If you deal with Electrical Discharge Machining (EDM) in the precision machining field, you already know that your choice of “dielectric fluid” impacts the machining results just as much as the quality of your equipment or electrodes. If you think of it merely as a coolant and use just any oil, you may experience…

In cost-reduction meetings at mold machining factories, one of the very first targets is often “consumables.” Among these, oils purchased by the drum seem to offer noticeable cost savings even with just a slight drop in the price per liter. Because of this, many workplaces often opt for cheaper products under the assumption that “all…
