How to distinguish the stable quality of a spark machine?

2021-11-09

　　After the recent waves of price adjustments from upstream raw material suppliers for EDM machines, with raw material prices continuously rising, how are low-priced EDM machines made? What are the different details? Don't they all look like EDM machines on the outside? Aren't they all used for mold forming discharge? Why did the price difference once appear so stark? The price gap is not small. Does buying a low-priced EDM machine really mean the customer is profiting? Are the appearance and essence really the same? This is exactly the focus I want to discuss with everyone today:

　　Castings: Let's start with castings: the quality of the casting directly determines whether the machine base will deform after long-term use. The weight of the casting also varies, and the design rationality of the casting differs. In short, if you pay attention to details, good things reveal the true essence of quality.

　　Wires: Next, let's talk about the wires in the EDM machine's electrical control box. Wires are divided into copper and aluminum wires, and obviously, there is a huge difference between the two. Copper wire has good conductivity and a long service life.

　　Scraping Process: The scraping of the EDM machine base is done by craftsmen with over 20 years of experience. The depth at each point and the scraped area directly affect the smoothness of the machine's feel, the degree of later running-in, maintenance rate, and so on.

　　Why do some EDM machines cause high labor loss, run slowly, and have uneven surface textures? All of this stems from differences in the craftsmen's assembly experience and is also directly related to the raw materials chosen by the EDM machine manufacturers. There are many more details, which I won't elaborate on here. In short, the more you understand and observe on-site, the more everything becomes self-evident.
