Haas Automation, Inc. UMC-750 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a 24.8" x 19.7" work table with a maximum workpiece weight capacity of 660 lbs, enabling it to handle medium to large components. It supports 5-axis machining with X, Y, and Z travels of 30", 20", and 20", respectively, and a B-axis rotary table with 145° rotation, facilitating complex multi-dimensional parts manufacturing. The vertical spindle supports both CT40 (standard) and optional BT40 tapers, operating at up to 8,100 RPM (standard) or 12,000 RPM (optional) with a 30 HP motor rated for 30 minutes, ensuring high-speed precision cutting and strong power delivery for diverse materials. Tool handling is managed via a 40-station SMTC (Self-Machining Tool Changer) with fast tool change times of 2.8 seconds (tool change) and 3.6 seconds (chip-to-chip), optimized for high productivity runs but without a pallet changer option. The rapid traverse rate reaches 1,200 IPM across all linear axes with a top feed rate of 650 IPM, offering efficient machining cycles while maintaining accuracy. The spindle taper standards accommodate a wide range of tooling: CT40 taper provides robust performance, while optional BT40 tooling supplies a symmetrical design favored in high-speed, high-precision machining due to better balance and stability. Overall, this machine is well-suited for advanced manufacturing environments requiring five-axis versatility, high spindle speeds, and substantial power for medium to heavy-duty milling tasks on sizable workpieces.
