Handtmann UBZ SD VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features an exceptionally large worktable measuring 95.43 inches by 39.37 inches, with an optional extended table size up to 492.13 inches by 78.74 inches, supporting workpieces up to 30,000 lbs. The machine operates on three axes (X, Y, Z) with travels of 551.18", 106.30", and 59.06" respectively, all capable of rapid traverse rates up to 1,575 inches per minute, enabling efficient high-speed positioning and machining. The spindle is vertically oriented, equipped with an HSK 63A taper for high precision tool holding, and delivers up to 30,000 RPM with a 251 HP motor rated for 30 minutes, ensuring powerful, sustained cutting performance for heavy-duty applications. The machine does not include a U axis or rotary/support tables by default, but an optional pallet changer is available to enhance automation and reduce cycle times. This configuration suits large-scale machining operations requiring long travels and high power, such as aerospace or heavy manufacturing sectors, providing robust support for very heavy workpieces and high precision via HSK toolholding technology known for secure, concentric spindle-tool engagement at high speeds. The high feed and rapid traverse rates combined with the large travel range support a wide variety of machining tasks including milling, drilling, and boring of large, heavy components. Overall, this machining center balances massive capacity, high spindle power, precise tool engagement, and rapid multi-axis movement for production-demanding, heavy-part CNC milling environments.
