GF AgieCharmilles’ Micron high-speed machining centers, which offer process-reliable tool measurement on the machine tool, include the HSM 400 LP Precision, HSM 400U LP Precision, and HSM 500 LP Precision. Intelligent Tool Measurement (ITM) provides optical tool measurement at full spindle speed. ITM records the tool tip with modern image sensors and then uses software to clean up the image, resulting in the ability to obtain a tool measurement with an absolute Z-reference in the micron range. The machines possess good thermal control characteristics, with systems cooling the drive groups in a targeted manner. Each of the linear axes, as well as the rotation/tilt unit, has its own cooling circuit. The Opticool concept, which also includes cooling of the spindle nose, allows for high-temperature stability. Quick dispersion of heat results in geometric stability that provides high repeat accuracy in axial movement.
