High Precision Multi-Tasking Takes a Turn

To machine difficult, high-hardness materials with extremely high accuracy, the rugged Nakamura-Tome SC-300IIMYB multi-tasking turning center from Methods Machine Tools uses an extremely rigid turret for powerful cuts and fast machining that increases capacity.

The NT Work Navigator in the Nakamura-Tome SC-300IIMYB multi-tasking turning center from Methods Machine Tools recognizes the coordinates of machine parts with non-round shapes, such as those in forgings and castings, without any additional costs involved. This eliminates the need for costly positioning fixtures and clamping devices. The Advanced NT Nurse System includes phase recognition (key for multi-tasking), direct chucking for transfer without positioning error, and precise synchronization of the left/ right-hand spindles.

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.
