By fitting a 50 W, Nd:YAG laser to the upper turret of a Traub TNC 30 mill-turn centre, components can now be laser profiled, small holes machined, features engraved or welded, sections of a turned part hardened, welded, engraved and burrs removed, using the non-contact tooling technology. The twin spindle Traub TNC 30 is available from Traub Heckert UK of Brackley. The laser head is located in the upper of the two turrets which has a Y-axis feed and functions in the same way as any other tool.
The installation of the laser does not interfere with other tools, so that a part can be machined in the normal way and the laser brought to action as part of a 'one-hit' machining process.
1 -more- TRAUB HECKERT MWC 6260 The 50W laser is able to machine steel with up to a 4 mm depth of cut and weld to a depth of 1.5 mm.
Because the machine features a Y-axis on the upper turret, profiling and off-centre machining can be carried out within a stroke of + 18 mm.
The TNC 30 has a bar capacity of 30 mm with a turning length of 270 mm.
The 11 kW spindle drive has a maximum speed of 7,000 revs/min.
The secondary spindle has a 26 mm capacity with 5.5 kW drive and maximum speed of 7,000 revs/min.
The twin turrets each have 12 all-driven positions from a 2.6 kW motor giving up to 8,000 revs/min and station to station indexing times are 0.4 secs.
In line with the laser machining, the TNC 30 can also be configured for special applications.
The secondary spindle, for instance, is designed as a quill with 330 mm stroke allowing parts up to 600 mm to be machined simultaneously by both turrets.
The secondary spindle can also act as a steady and the linear Y-axis interpolated with X and Z axes, with one or both C-axes on the main and secondary spindle
