Methods Machine Tools Inc. is making the Nakamura-Tome Super NTY3 Multitasking Turn/Mill Machining Center available in larger-capacity versions, referred to as “Jumbo” stations. These new versions are fitted with 10-in. (254-mm) chuck on the left and right spindles, and will handle bars up to 3.15 in. (8 0 mm) on the left and 2.8 in. (71 mm) on the right. “Ample room is provided for a big swing and a large turning diameter up to 12.8 in. (325 mm),” according to Methods.
Methods supplies precision machine tools and accessories and is the exclusive importer of Nakamura-Tome machines for the U.S. and Mexico.
The Jumbo systems combine turning and milling in one machine, and because they offer “100% stock-on turning and machining,” MMT said the new designs “virtually eliminate lost productivity due to tool changes.”
The Super NTY3 Jumbo has three turrets, each with a Y axis, dramatically outperforming single-tool multitasking machines, allowing one-pass complete turning/machining/finishing and reducing part cycle times.
Jumbo systems are offered in two models: the NTY3 Jumbo Super Mill 16-Station Turret (90 mm) System and the NTY3 Jumbo Standard 12-Station Turret (100 mm) Station. Both models have rigid turrets with different configurations: the 16-Station Super Mill has 48 milling stations and the 12-Station Standard System provides ½ indexing for 72 stations. Both systems offer 10/5 HP and 40-Nm torque, with accelerating Y-axis total travels of +/- 2.16 in. (54.9 mm) or 4.33 in. (110 mm).
Also, both systems offer either 3,000 or 6,000 RPM milling motors that can simultaneously machine two flat surfaces (top and bottom) on one spindle and one surface on the other. Up to 35/30 HP left and right spindles are available for shaft/work turning.
The 12-Station Standard System offers compatible tooling with the current Nakamura WT-300 and TW-20 models.
The Super NTY3 Jumbo Systems are supplied with Fanuc 31iA CNC control, with nanometer resolution for smooth movement and improved accuracy. Overload detection and NT Nurse programming/monitoring software are standard, as is NT Work Navigator (torque-type) software, which eliminates the need for positioning jigs and fixtures.
“With the introduction of the Super NTY3 Jumbo Systems, we are now able to provide our customers with a multitasking solution that adds increased capacities and maintains the decreased cycle times provided in the Super NTY3,” stated Methods Machine Tools’ Richard Parenteau, Director of Applications Development and Nakamura-Tome Product Manager.
