Multitasking Turning Center with Automated Load/Unload

Methods Machine Tools, Inc. (Sudbury, MA) offers the Nakamura-Tome NTRX-300 multitasking turning center that features complete parts machining in one operation, with a built-in load/unload automation system and advanced operator recognition management software. It features true opposing twin spindles, an 8 in A2-6 25 hp or a 10 in A2-8 30 hp. The machine has a robust 25 hp tool spindle with 12,000 rpm and full 5-axis capabilities, a Fanuc 31I A5 control, and offers a large machining area for application versatility. It can machine a 10 in square on the face of a part with no C-axis rotation required due to X-axis capability of 5 in (125 mm) below center travel and a Y-axis capability of 10 in (250 mm). With a compact footprint of only 104 sq ft (9.66 sq m) and weighing in at a hefty 37,480 lb (17,000 kg) for maximum rigidity, the NTRX-300 is available in two models: 8 in (203 mm) chucks with 2.5 in (63.5 mm) bar capacity or 10 in (250 mm) chucks with 3.15 in (80 mm) bar capacity.

The NTRX-300L is a full 20 in (1,850 mm) longer in the Z-axis than the NTRX-300, creating a larger work envelope for larger part applications. It also offers three additional tools with a maximum length of 15.75 in (400 mm) in a separate storage area. This machine has an extra-long 72.83 in (1,850 mm) distance between spindles to eliminate any interference of tooling during multitasking. It also has a standard 40-tool ATC and is available with options for 80-tool and 120-tool ATCs. Both the NTRX-300 and NTRX-300L have a unique bed design with a vertical column structure mounted on a horizontal machine bed for superb rigidity and thermal stability. A uniform load applied over the machine bed during slide movement ensures exceptional stability. The compact design also allows easy reach of the spindle center and a versatile operation panel ensures optimum comfort for the operator.

Both machines feature an advanced graphic user interface for ease of operation on a large 19 in color LCD monitor. Nakamura-Tome (NT) Smart X Operation Software (using Windows v.8.1) offers an Operation Level Management Function to view operator clearance level, a Productivity Monitor Function that shows the status, productivity graph and capacity utilization of the machine, and a Loading Monitor Function that offers detailed load information. NT setting screen commands and buttons are all integrated into one screen for easy operation. The NT Smart X Screen enables an operator to view the NC program while watching 3D interface check, or look at CNC coordinates while watching the machining area through a video camera. Both machines also offer an NT Collision Guard feature to avoid machine collision and an air bag function to minimize damage in the event of a collision. Voice guidance, production management and 3D collision check are all furnished standard. CAMplete TruePath Turn/Mill software (an integrated suite of G-code editing, optimization, analysis and verification tools that enable a full range of turn/mill functions) is also standard.
