Designed for high-precision applications in the tool and mold industry, GF AgieCharmilles says its Mikron HSM 300 MoldMaster offers quality surface finishes and high accuracy while also ensuring time-optimized high-speed cutting conditions. The machine includes features and benefits of the company’s GraphiteMaster line, a product consolidation that enables users to choose between MoldMaster (MM) and GraphiteMaster (GM) configurations, increasing flexibility in the job shop.

With fast linear axes and a 30,000-rpm, high frequency spindle, the integration of a pallet changer allows repetitive machining without interruption in multi-shift operations.
Built on a polymer granite base, the machine provides the damping properties and stability essential for high speed milling. The single-casting construction improves machining accuracy, producing better thermal stability for higher workpiece surface quality and decreased tool wear. Additionally, the machine is outfitted with zero-play linear guides, high-resolution glass scales and preloaded ballscrews to ensure accurate positioning and high rigidity with axis acceleration rates ranging to 1.2G.

Previously found on GM products, the dust extraction system with suction frame is fully integrated in the machine base. Nozzles surrounding the machining spindle deliver focused air blasts directly to the machining point for dust removal. In addition, a constant underpressure is maintained in the full enclosure to confine all dust to the machining area, creating a constant flow of fresh air that protects the guides and the ATC from graphite dust.

The machine also contains a number of features for use in the workshop, including smart machining modules, which operate sensors that allow machinists to utilize the Advanced Process System for monitoring and recording spindle vibrations. And like most of the company’s high speed machines, it also uses the Heidenhain iTNC530 control system to achieve the speed and control for complex applications.
