Mikron Graphite Series

High speed milling in compact format
The Mikron Graphite Series is a high-speed Milling machine series dedicated to graphite machining. With its experience in tough high-speed Milling in combination with a dedicated three-axis graphite machine, GF provides the optimum solution for dry graphite Milling. The unique design provides clean, dry and wet machining for high accuracy, surface quality and dynamic processing.

New technology for best Milling results

Get highest precision and unbeatable surface quality with the Step- Tec Spindle’s 42,000 rpm maximum operating speed. Your graphite production time is shortened by the Spindle’s short run-up and break-in time. The Spindle lifetime is increased by oil-air lubrication of its bearings.

Clean machining

Overcome the difficulties of cutting graphite with our graphite package: The machine’s linear axes are covered and protected. All linear axes are lubricated by automatic central grease lubrication, and a strong vacuum dependably removes graphite dust.

Perfectly flawless surfaces

No polishing is necessary with the Mikron Graphite Series’ finishing capabilities. Ra 0.4 µm surface fishes and ±5 µm accuracy ensures the quality required for demanding glass mold and electrode applications – and allow for the shortest end-to-end production process possible.

Unparalleled quality with Step-Tec Spindles

The highest precision and unbeatable surface quality is easily achieved with a 42,000 rpm Step-Tec Spindle. The short run-up and break-in times cut down on total production time, while the oil-air lubrication and other advanced feature help to maximize the spindle’s lifetime.

Get parts done right the first time

GF Machining Solutions’ industry-leading high-speed machining technology, the ±1 µm repeatability of System 3R reference systems and a flexible, robust machine design with powerful dust extraction capabilities makes reliable, around-the-clock production a reality.

Machine graphite faster than ever before

As the fastest graphite-specific machines on the market, the MILL S Graphite series delivers highly dynamic performance that enables 25% faster cycle speeds compared to competitors’ machines – and integrated automation pushes the productivity improvements even further.

Electrodes

Precise graphite electrodes boost die-sinking EDM’s productivity and reduce costs – and as demand rises, lead times get shorter and mold makers require automated, reliable processes to maintain the necessary precision, flexibility and productivity for the lowest per-electrode cost. The MILL S Graphite series’ dust exhaust technology, integration with System 3R WPT1+ automation.

Precision for glass mold perfection

Smartphones with sophisticated glass touch screens are increasingly common – and the glass molds used to produce these screens have only become more challenging. They require up to ±5 μm precision, Ra 0.4 μm surface finish and as many as five hours of machining in wet or dry conditions, all to leave behind a perfect mold without a single milling mark.
