The HSM 400U LP is the latest high-speed milling innovation from GF AgieCharmilles (Lincolnshire, IL) and was designed for ultimate precision and supreme surface quality. The HSM 400U LP provides five-axis simultaneous high-speed machining and delivers powerful performance and precision on all five axes.

The unit is extremely dynamic and fast, and achieves speeds up to 250 rpm on the rotational axis and up to 150 rpm on the swivel axis, with a B-axis swivel range of 220 degrees. The machining center also uses a liquid cooled, linear direct drive motor technology to allow for short setting times and high dynamic rigidity of the attitude control. Additionally, the linear direct drive combines with central oil lubrication to reduce friction-induced wear and ensure excellent, long-term precision.

With powerful vector spindles available at 30,000, 42,000 or 54,000 rpm, the HSM 400U LP also provides excellent surface finish and part detail, while significantly reducing machining time for semi-finishing and finishing operations. The machine¹s high dynamics and 1.7 g acceleration help facilitate the reduction of non-productive time and help to maximize spindle utilization.

The unit possesses the capability for 24/7 unattended machining using the optional pallet changer with 20/48 pallets. This fully integrable pallet magazine further enhances the machine¹s automation potential. The pallet changer can be loaded while the machine is cutting, leading to minimum idle time for the machining center.

The company has equipped the unit with a Heidenhain iTNC 530 control system and smart machining modules that provide advanced levels of monitoring critical to the production of high value precision medical, aerospace and mold inserts. The system allows the machine to automatically check and evaluate tools and workpieces, inspect tools for breakage and perform measurements of the workpiece. Additionally, the smart machine modules automatically monitor spindle vibration, calibrate machine geometry and transmit process status messages to an operator¹s cell phone
