Try the special magnet filter for improving the surface roughness and precision of EDM products.

basic information

■Removal of fine particles is possible Magnum can capture fine magnetic particles (submicron: 10μm to 0.07μm) that cannot be removed by filters using filter paper or mesh, such as cartridge filters. ■No clogging Due to its special structure, where magnets are sandwiched between special plates, it does not block the flow path in the area where iron powder is captured. Therefore, it does not cause any clogging or pressure loss. Even when the capture capacity limit is reached, it does not hinder the operation of the device. ■Powerful capturing ability The magnets enhance the magnetic flux due to their special arrangement, resulting in a significant difference in the capturing ability of iron powder compared to simple magnets. Unlike conventional magnetic filters, which can only capture contaminants from liquids close to the magnets, this structure greatly improves the cleanliness of the fluid. ■No re-release Captured contaminants are accumulated in a strong collection area separate from the flow path. The dangerous phenomenon that can occur with regular magnetic filters, where the magnetic force weakens as you move away from the magnet, causing once-captured and solidified contaminants to re-release as a mass, does not occur at all.

Detailed information

  EDM (Electrical Discharge Machining) can be considered a very useful machine tool that can process extremely hard materials like cemented carbide. Due to the fine particles of the workpiece that are scattered during the discharge machining, it is necessary to adequately filter them using a filtration system, as they become suspended in the cutting fluid. However, while existing filters can filter to some extent, they cannot remove all fine particles smaller than 10 μm. That said, using finer mesh can easily lead to clogging and increase the frequency of replacements, making it economically challenging to use excessively fine products. Naturally, when machining workpieces like cemented carbide, very hard contaminants that are much harder than the materials of the system components will be scattered. Therefore, if the cutting fluid is not sufficiently filtered, very hard fine particles can become a fundamental cause of excessive wear. In other words, among the ultra-fine particles scattered by the impact of electrical discharge machining, there are particles that are much smaller than the mesh of standard filters. Consequently, the impact generated by the collision of fine particles will be significant, as they are all very hard and moving at high speeds. If not adequately filtered, a large portion of the contaminants from the cemented carbide will remain suspended in the cutting fluid, which will likely affect the finishing accuracy of the products.

  In fluid systems, iron-based contaminants are present and act as catalysts for the "wear chain reaction." The "wear chain reaction" is described as a process where a small number of particles circulate within the system, generating additional particles, which, along with the original particles, exponentially produce even more particles.

  The biggest threat to hydraulic systems actually used on-site is iron particles, and the mere presence of these particles significantly increases the likelihood of problems manifesting as decreased performance and increased maintenance costs.
