Nd:YAG/Fiber/CO2 Swivel Axes |
 | These SD-35/SD-40 swivel axes (fiber/Nd:YAG or CO2) are supplied by LT Ultra with a direct drive unit (torque motor) and come with an incremental measurement system, a leveling mounting flange, pneumatic brake as well as our 3D anti-collision unit. The omission of mechanical rotating parts guarantees consistently high machining accuracy, and long service life. The unit has a ±160° of freedom, and a variety of applications can be served with the appropriate process heads for cutting and/or welding. A fiber collimator can be integrated within the unit or mounted separately, and the unit’s clear aperture is 35 mm (fiber/Nd:YAG) or 40 mm (CO2). |  | The LT Ultra RSD-40T/RSD-60T combine two swivel axes, which are both fitted with torque motors and therefore have the same advantages as the single-axis unit. The rotational axis has typically ±200° or more of freedom; the head has a direct water-cooled plane mirror enhanced with a low absorption coating. One of the mirror units could be replaced by an existing adaptive optic, which will then provide the head with a dynamic autofocus function. The unit's clear aperture is 40 mm or 60 mm, and it will be available as of Q1 2010. |  This LT Ultra RSD-60 machining head has been in production for the past 10 years and is generally used by manufacturers of 5-axes special purpose (CO2) machines. The rotational axis has an unlimited freedom of movement, and the exceptional precision drive units are combined servomotors according to the customer’s specifications. The rotational axis has typically ±200° or more of freedom. Here too water-cooled plane mirrors are enhanced with low absorption coatings for 1064/1070 nm and CO2 applications. As an option, one of the mirror units could of course be replaced by an existing adaptive optic, which will then provide the head with a dynamic autofocus function. A free aperture of 60 mm suits applications where wide beam diameters are required.
