3D Laser Heads
RSD-60 Rotary/Swivel Unit

For more than 10 years, LT-Ultra has been developing and perfecting laser heads with motorized pivoting swivel axes, such as the RSD-60 rotary/swivel unit pictured here) for 3D applications. Most heads these days are used for chamfer-cutting of large sheet metals using CO2 lasers with a typical power rating of 6kW. The underslung head is mounted on an axis with a limitless rotational freedom of movement and yet is continually supplied with process gas, cooling-water and all electric signals and power.

Adaptive mirrors are generally used for focal shift - in other words, to adjust dynamically the beam's focal point for optimum cutting precision and efficiency.

These heads are often supplied with custom-specified servomotors and have a clear aperture of 60 mm.

SD-40 Swivel Unit with Torque Drive

 

This SD-40 swivel-axis with torque drive is one of our latest developments.

The integrated high-acceleration direct-drive torque motor does not have any mechanical gearing and its positional accuracy of up to 10 arc seconds is achieved through the integration of a glass-scale encoder.

This head possesses a clear aperture of 40 mm and is fitted with water-cooled coated copper mirrors as standard.

LT Ultra offers this unit with available standard lens-cutting heads in combination with a 3-D collision clutch of extreme repeatability (a safety feature - should the head collide with an object, then it disengages preventing it from being damaged. Once the danger has passed, the head resumes with negligible deviation from its previous position).

This head is a perfect tool for tube cutting applications and all other high-performance positioning tasks as its positional accuracy does not deviate over time.

We are currently in the process of developing a 2-axis variant with torque drives in both axes to complement our current portfolio, which will be available in the first quarter of 2010.
