GF Agie Charmilles’ Mikron HSM 300 MoldMaster now includes the features and benefits of the company’s GraphiteMaster line. According to the company, the product consolidation enables users to choose between MoldMaster and GraphiteMaster configurations, increasing flexibility in the job shop.
The mill features fast linear axes and a 30,000-rpm, high-frequency spindle. It is designed specifically for high-precision applications in the tool and mold industry. The mill is said to offer excellent surface finishes and accuracy while also ensuring time optimized high speed cutting conditions. The integration of a pallet changer allows repetitive machining without interruption in multi-shift operations for increases flexibility and efficiency.
Built on a polymer granite base, the mill is said to provide damping properties and stability essential for high speed milling. The single-casting construction improves machining accuracy, producing better thermal stability for a quality workpiece surface and minimal 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 of up to 1.2G.
The Graphite Extraction package option offers a clean and efficient machining process where the dust extraction system is fully integrated into the machine base. Nozzles surrounding the machining spindle deliver focused air blasts directly to the machining point for optimal dust removal. A constant underpressure is maintained in the full enclosure to confine all the dust to the machining area, creating a constant flow of fresh air to protect the guides and the automatic tool changer from graphite dust.
The mill uses a Heidenhain iTNC530 control system to achieve the necessary speed and control to perform complex applications.
