Graphite Mill Also Processes Hardened Metals

Eastec 2019: EDM Network and Chmer EDM’s 30,000-rpm high-speed Dust Free Graphite Mill can mill graphite electrodes in EDM-compatible oil, applied in an oil shroud or curtain that surrounds the spindle to capture all of the graphite dust from the milling process.

EDM Network and Chmer EDM’s 30,000-rpm high-speed Dust Free Graphite Mill can mill graphite electrodes in EDM-compatible oil, applied in an oil shroud or curtain that surrounds the spindle to capture all of the graphite dust from the milling process. All of this dust is then carried to the 30-micron filtration media where it is filtered out of the oil; the oil is then cooled and used again in a continuous process.

In addition to the dust-free graphite milling process, the larger models of this high-speed mill can also machine hardened metals up to Rc 63, offering moldmakers a complete milling product for their electrodes and their molds, according to the company. The graphite mill is available with either the Chmer CNC or the Siemens 828D control and drives. The machine is offered in either ballscrew drives or Chmer or Siemens linear motor drives for higher speeds and finer resolutions.
