The Mazak Variaxis i-800T is a 5-axis vertical machining center built on the reliability that has made the Variaxis line a staple in aerospace, medical, energy, and high-mix precision shops. This 2023 example combines full 5-axis milling with integrated turning on a single tilting-rotary trunnion table, so complex prismatic and round parts can be finished complete in one setup. It offers X/Y/Z travels of 29.5 x 35.0 x 23.6 inches, a 10,000 RPM CAT50-taper spindle driven by a 40 HP motor, and 1,890 ipm rapid traverse on all linear axes. Workholding rides on a trunnion-style A-axis tilt and a high-speed C-axis turning table fitted with dual 24-inch 3-jaw scroll chucks, while a 30-tool chain-type automatic tool changer keeps a broad range of tooling ready. Control is Mazak's Mazatrol SmoothAI CNC with a 19-inch color touchscreen, and the machine comes equipped with a Renishaw RMP600QE radio work probe, glass scale feedback on all axes, a two-pallet changer, flood plus 1,000 PSI high-pressure through-spindle coolant, a chip conveyor, spindle chiller, AI thermal shield, and absolute positioning for dependable accuracy on long runs.
Compared with the previous-generation Mazak Variaxis 730-5X II it effectively replaces, the i-800T is a meaningfully more capable machine, not just a newer one. It steps up to Mazak's Mazatrol SmoothAI control - a large touchscreen platform with faster processing, advanced look-ahead, and on-machine measurement - in place of the older Matrix-generation control, and it expands the work envelope to the 800 mm class for larger, taller parts. The i-800T also adds true integrated turning through its high-speed C-axis table, so parts that once needed a separate lathe operation are completed in a single setup, and it benefits from roller-type linear guides, ball-screw and spindle cooling, and AI thermal-shield compensation for tighter accuracy over long unattended runs. For a buyer, that means the throughput and part complexity of a current-generation 5-axis mill-turn platform, now available as a used machine.
