High-Speed Milling Machines Designed for Graphite Moldmaking

GF Machining Solutions’ high-speed Mikron Mill S 400/500 Graphite and Mikron HSM 500 Graphite are dedicated specifically to graphite machining.

GF Machining Solutions’ high-speed Mikron Mill S 400/500 Graphite and Mikron HSM 500 Graphite are dedicated specifically to graphite machining. Graphite glass molds for glass end products are especially common in markets such as information and communications technology (ICT), while graphite electrodes are typically demanded by the automotive, electronic components, aerospace and packaging sectors. These two machines are designed to mee the peculiar challenges of machining graphite in these contexts. 

The Mill S 400/500 Graphite is said to resolve the challenges of machining graphite molds for glass end products. As ambient workshop temperatures fluctuate and machining speed changes, process stability is maintained thanks to an intelligent thermal management system and thermostabilized machine body. Precision and stability at the tool tip are insured by the Step-Tec HVC140 spindle, with speeds ranging to 42,000 rpm and 13.5 kW of power.

Both machines are also designed to deliver the precise graphite electrodes that boost die-sinking EDM productivity and reduce costs. 

The Mikron Mill S 400/500, available with three axes, sets a benchmark for axis dynamics and spindle speed, taking users beyond fast dry and wet graphite machining, the company says. Besides long-term precision in graphite, the machine can also handle a range of materials in a clean environment.

The Mikron HSM 500 Graphite suits dry machining with a well-established process, a simple and compact solution, and a shop free of graphite slurry accumulation, according to the company. The machine’s Step-Tec HVC140 spindle, integrated dust extraction and integrated System 3R WorkPartner (WPT1+) part-changing robot combine to enable the machining of small graphite electrodes.
