High-Performance VMC for Mold and Die Work

The Tongtai TMV-1050Q-II vertical machining center available from Absolute Machine Tools is well-suited for high-volume machining applications as well as mold and die work.

The Tongtai TMV-1050Q-II vertical machining center available from Absolute Machine Tools is well-suited for high-volume machining applications as well as mold and die work. The high-performance, heavy-duty machine features a 15,000-rpm spindle, 1,890-ipm (47,250 mm/min) rapids on all three axes, and oversized servomotors and ballscrews.

The 15-hp, high-torque, direct-drive spindle is oil cooled for thermal stability. An electronic high/low switch gear provides a range of power and torque. The 2.75" (70-mm) spindle shaft has size bearings to maximize stiffness and cutting stability. The machine is equipped for high-pressure through-spindle coolant, with 300- and 1,000-psi coolant pumps available as options.

The machine features NSK linear ways on all axes with large-diameter 1.57" (40-mm) pre-tensioned ballscrews. High rigidity enables cutting feed rates ranging from 0.01 to 944 ipm, positioning accuracy of ±0.0002" (0.05 mm) and repeatability of ±0.0001" (0.0025 mm). The worktable measures 43.3" × 23.6" (1,082 × 590 mm) and X-, Y- and Z-axis travels measuring 41.3" × 23.6" × 20.8" (1,032 × 590 × 520 mm), respectively. A 30-tool, synchronous-arm-type automatic toolchanger provides 2 sec. tool changes. Standard twin screw-type chip conveyors discharge at the rear of the machine to minimize cleaning time, and a caterpillar lift-up-style chip conveyor carries chips to a hopper.

The FANUC 31iM-B control features a full conversational Manual Guide i shopfloor programming system, and an optional high speed machining package permits high speed point-to-point machining capability
