NEW TURNING MACHINES ADD FURTHER PRODUCTIVITY TO NAKAMURA’S RANGE

September 2005

At EMO, Nakamura-Tome added even more productivity to its established twin-spindle concept with the launch of two new turning machines – a twin-spindle three-turret machine with Y-axis on each turret, and a compact multi-tasking CNC turning and milling machine – both ideally suited for the production of a wide range of complex components in one operation.

The Super NTJX is a twin-spindle machine with a lower 24-tool turret and an upper tool spindle with a servo-driven 40-station automatic tool changer. The tool spindle combines 7.5 kW of power with a Y-axis stroke of 140mm and a B-axis positioning range of plus or minus 115o to provide a highly productive machining capability. The tool magazine can be expanded to accommodate up to 180 tools.

The lower turret adds a further 24 tools – with milling capability of 5.5Kw and the extra productivity of another Y-axis – this time with a 70mm stroke.

The ability to perform simultaneous machining with two tools and two Y-axes on either or both spindles can balance operations across the two spindles and dramatically reduce cycle times. Indeed, according to Nakamura, the second Y-axis on the lower turret can increase productivity and reduce part costs by up to 50%.

The latest Fanuc 31-IA control can handle up to four-plus-four axes simultaneously and offers operator-friendly functions for reduced setup time and maximum productivity.

The Super NTJX can turn a maximum diameter of 245mm and a maximum length of 1090mm. It has a chucking capacity of up to 210 mm diameter and can take up to 65mm bar through the spindle.

Nakamura’s second launch at EMO was the equally impressive Super NTY3 – a twin-opposed-spindle turning centre with three independent turrets and milling capability.

Uniquely the Super NTY3 has Y axis capability on each of the three turrets. Each spindle has a dedicated upper turret, and the machine has a lower turret that can service either spindle, operations can be balanced to remove bottlenecks and deliver the shortest possible cycle times. Each turret has 24 tool positions, offering up to 7.5kW of milling power.

The Super NTY3’s unique configuration offers possibilities that include simultaneous machining with three tools and three Y-axes and four-axis machining on either turret.

On a component such as a pneumatic valve block, for example, upper and lower turrets can use the same program to simultaneously machine opposite sides of any prismatic features, or perform simultaneous helical interpolation on the upper and lower faces. In fact, Nakamura says that the Super NTY3 can reduce cycle times by up to 60%, compared to a twin-turret machine with just one Y axis.

The Super NTY3 can swing parts up to 175mm diameter and 588mm, and has a chucking capacity of 165 mm diameter and a 42mm bar capacity through either spindle – all within a footprint of just 2780 by 1970 mm.

Richard Turner, Managing Director of Turning Technologies, the sole UK distributor of Nakamura-Tome’s high precision turning centres said, “Nakamura has already set the standard for high-precision twin-spindle, twin-turret turning centres. These new machines show that they are determined to keep on pushing high-productivity turning to its limits. These new machines will be available in the UK early next year and we are sure there will be a high level of interest from current and potential customers.”
