Now available from Traub Heckert UK of Brackley, the Traub TNA 700 has an all up weight of some 21 tonnes and has been developed for high rates of chip removal with the ability to be very flexible for tooling layout.
For its size, the machine is able to maintain high tolerance levels and surface finish.
The machine can be specified in four capacities under the designations D90 and D102, which reflect maximum bar diameter, and all are available with 700 mm diameter swing and choice of 1,250 mm or 2,000 mm turning lengths.

The TNA 700 has a tubular cast bed which is extremely torsion resistant with a thermo-symmetric headstock and linear guideways.
Access for setting and workpiece loading is a prime consideration and ergonomic positioning of the Traub 64-bit TX8i control makes the operator task simple.
Both main and optional counter spindle are identical with 57 kW, 3,500 revs/min and 363 Nm of torque for the D90.
This increases to a massive 68 kW, 3,000 revs/min and 900 Nm, on the D102.
In addition, the D102 can be specified with planetary drive which increases the torque of the spindle to 2,000 Nm.
C-axis positioning is either by direct drive to a resolution of 0.001o or by the planetary drive.
Highly dynamic axis drives have overload clutch protection and absolute measuring scales eliminate referencing and ensure high contouring accuracy and positioning.
On the upper bed guideway, two 10 or 12 station disc turrets with 17 kW tool drives ensure high power milling can be performed at up to 6,000 revs/min.
Each turret has an optional 220 mm Y-axis cross-feed.
In addition, 10 or 12 station Traub developed crown turrets can be specified to allow maximum clearance between tools such as large boring bars.
Also, up to a 30 tool magazine and toolchange system can be specified.
A turret milling spindle is also available as part of the machine customisation package for specific applications.
Graphic object contour programming, block-by-block or graphic simulation are standard with the Traub Polyform software.
This simplifies programming of milled contours in X, Z and Y planes and includes cutter radius compensation.
