The Mikron HSM 600U LP high-speed milling center from GF AgieCharmilles uses linear motor technology in the main machine axes and optimized direct-drive motors for the B and C axes to provide simultaneous five-axis, high-speed machining and deliver high precision and superior part surface finishes. The machine’s 36,000-rpm vector spindle is designed to improve surface finish and part detail while reducing machining time for semi-finishing and finishing operations.
The machine can accommodate larger workpieces for a variety of applications, including hard metal machining. The rigid design features X- and Y-axis travels measuring 31.49" and 23.62". A polymer granite portal and base are said to increase vibration damping capabilities. Additionally, high-strength cast iron comprises the worktable and X-, Y- and Z-axis slides, which are reinforced by longitudinal ribs and wide sections.
The milling machine is suited for prototype production, die making, and fully automated, low-volume serial production in which accuracy and surface finish are critical. With acceleration of 32.81 ft./sec2, the machine can achieve programmed feed rates of 196 ft./min. in the simultaneous operation of serial production.
A cooling unit in each of the linear axes and in the round swivel unit systematically draws heat out of the machine, creating geometric stability and increased repeatability of movement guidance.
