The new HSM 400U LP is the latesthigh-speed milling innovation from GF AgieCharmilles. Designed for ultimateprecision and supreme surface quality, the HSM 400U LP provides 5-axissimultaneous high-speed machining and delivers powerful performance andprecision on all five axes.The HSM 400U LP is extremely dynamic and fast, and achieves speeds up to 250RPM on the rotational axis and up to 150 RPM on the swivel axis, with aB-axis swivel range of 220 degrees. The machining center also uses a liquidcooled, linear direct drive motor technology to allow for short settingtimes and high dynamic rigidity of the attitude control. Additionally, thelinear direct drive combines with central oil lubrication to reducefriction-induced wear and ensure excellent, long-term precision.With powerful vector spindles available at 30,000, 42,000 or 54,000 RPM, theHSM 400U LP also provides excellent surface finish and part detail, whilesignificantly reducing machining time for semi-finishing and finishingoperations. The machine’s high dynamics and 1.7 g acceleration helpfacilitate the reduction of non-productive time and help to maximize spindleutilization.The HSM 400U LP possesses the capability for 24/7 unattended machining usingthe optional pallet changer with 20/48 pallets. This fully integrable palletmagazine further enhances the machine’s automation potential. The palletchanger can be loaded while the machine is cutting, leading to minimum idletime for the machining center.GF AgieCharmilles equipped the HSM 400U LP with a Heidenhain iTNC 530control system and smart machining modules that provide advanced levels ofmonitoring critical to the production of high value precision medical,aerospace and mold inserts. The system allows the machine to automaticallycheck and evaluate tools and workpieces, inspect tools for breakage andperform measurements of the workpiece. Additionally, the smart machinemodules automatically monitor spindle vibration, calibrate machine geometryand transmit process status messages to an operator’s cell phone.The HSM 400U LP's unique monobloc bridge design achieves high precision bymaintaining a high level of rigidity. The machine’s polymer graniteconstruction provides increased performance in the areas of vibrationdampening and thermal stability, extending tool life and reducing operatingcost. Also, attention to the ergonomics of the machine’s design allows foruncharacteristically easy access to workpieces.
