Milling - High Speed Machine - Mikron MILL S 400

Surface finish, precision, process reliability and productivity are among the distinct challenges associated with the information and communications technology (ICT) and automotive sectors’ requirements for graphite molds for glass end products and graphite electrodes. GF Machining Solutions’ high-speed Mikron MILL S 400/500 GRAPHITE machines are dedicated specifically to graphite machining, helping users master precision over time and meet their customers’ expectations for flawless surface quality.

Process stability, parts quality and shop floor productivity are must-haves for customers’ production of the graphite molds that are shaping the glass for today’s fast-moving ICT and automotive markets. New products—like high-end curved touch screens—require molded glass and drive the increasing need for machined graphite molds. The MILL S 400/500 GRAPHITE makes those impeccable 3D glass products—and more—possible. Graphite mold manufacturing for glass end products presents specific manufacturing challenges. They require ±5 µm precision, Ra 0.4 µm surface finish and they must be absolutely free from milling marks.

The Mikron MILL S 400/500 GRAPHITE provides the ideal answer to these challenges. It combines the well-established MILL S 400/500 that set a benchmark in terms of speed and surface finish with high-speed Milling (HSM) technology and a dedicated, high-precision Step-Tec Spindle.

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.
