The common processing method of graphite processing is discharge machining, and the method of milling graphite is rare. Although graphite is a very easy to cut material, the graphite material must be of sufficient strength to avoid damage during operation and milling process. At the same time, the electrode shape (thin wall, small rounded angle, sharp change) and so on also to the graphite electrode grain size and strength of higher requirements, which led to the processing of graphite workpiece prone to collapse,
Jager Electric Spindle internal cone diameter jump is less than 1 μ, fully capable of processing graphite extremely brittle materials.
Germany Jager Electric spindle in the field of graphite electrode processing has many years of experience to provide users with a complete solution.
The mainstream trend of graphite electrode milling in the future 1, the increasingly complex mold geometry and product application diversification led to the spark machine discharge accuracy requirements are higher.
The advantage of graphite electrode is that it is easy to process, the discharge processing is high, the graphite loss is small, but the processing efficiency is low, and the high precision electric spindle milling method provides the processing efficiency greatly! 2, graphite electrode is easier to process, and processing speed is significantly faster than the copper electrode. For example, the use of milling process graphite processing, its processing speed than other metal processing fast 2~3 times and no need for additional manual treatment. and processing graphite motor in the process of dust defense, which requires a high degree of electrical spindle seal, Jager electric spindle using labyrinth type gas seal structure, can effectively prevent cutting crumbs, dust into the protection of the spindle! 3, the graphite electrode and the traditional copper electrode design is different. Many mold factories usually in the copper electrode roughing and finishing have different reservations, and graphite electrodes use almost the same amount of reserve, which reduces the CAD/CAM and machine processing times, this reason alone enough to greatly improve the accuracy of the mold cavity.
