The Nakamura-Tome SC-300IIMYB multi-tasking turning center from Methods Machine Tools, Inc. (Sudbury, MA) has an extremely rugged machine structure with a massive 45 deg slant bed and box-way slides on all axes, providing the rigidity required to machine difficult, high-hardness materials with extremely high accuracy. This turning center features a 3,500 rpm main spindle with a 3.5 in (89 mm) bar capacity, a large 4.7 (120 mm) Y-axis travel and 10 hp milling function that offers increased capacity, enabling fast machining with a cutting depth of .35 in (9 mm). A 30/25 hp wide-range motor facilitates powerful cuts. Extremely rigid, the turret holds 12 driven or 24 stationary tools. The SC-300IIMYB is an environmentally friendly, energy-saving machine featuring a compact design with machine dimensions of 157.3 in (3,995 mm) length x 83.6 in (2,130 mm) width x 90.5 in (2,300 mm) height. The machine weighs 19,840 lb (9,000 kg).
The Nakamura SC-300IIMYB features a 15 in high-resolution color display LCD panel that works in conjunction with the latest Fanuc 0i-TF control to give a high degree of functionality, coupled with fast processing speeds and 1,280 m of part program storage length. The turning center comes equipped with the NT Work Navigator that can recognize the coordinates of machine parts with non-round shapes, such as those in forgings and castings, without any additional costs involved. This cost-cutting feature eliminates the need for costly positioning fixtures and clamping devices. In addition, the Advanced NT Nurse System all-in-one software package is included that provides convenient, easily operated support for the operation, programming and production on the machine. Critical functionality includes phase recognition (key for multi-tasking), direct chucking enabling transfer without positioning error, and precise synchronization of the left/ right-hand spindles. Additional functions include a load monitor for identifying tool wear/ breakage, tool life management and operation condition monitoring.
The machine is equipped with an “airbag” standard safety feature that greatly reduces the impact and force of a machine collision. Should a crash occur, within 4 ms after the crash, servo motor-feeding direction is reversed and the machine will stop in EMG mode.
