The LaserTurn® series of products are the first
dedicated motion subsystems targeted directly at cylindrical laser
processing applications. The integrated linear-rotary system combines
automated material handling functionality and wet cutting operation
with high performance direct-drive linear and rotary motion. The
pneumatically-actuated 3-jaw gripper has a clear aperture for
product feedthrough, and can be configured for O.D., I.D., or
odd form gripping with various jaw geometries, while the ER collet
supports tubing diameters from 0.5 mm to 30 mm.
Integral Tooling Platform
The LaserTurn® series can be equipped with front and rear
tooling platforms that include tapped holes on four surfaces for
various fixture mounting. The tooling platform is bolted directly
to the base of the linear stage providing a stiff, common inertial
frame of reference. Custom fixtures such as bushing alignment,
part collection, or automated material advance assemblies can
easily be attached. Metric or English-based hardware and hole
patterns are available as are custom configurations with application
specific features.
Automated Material Handling
The LaserTurn® is a complete motion and material handling
subsystem. The system includes an automated, pneumatically activated
3-jaw gripper or ER collet for part holding. The 3-jaw gripper
has a clear aperture for product feedthrough and can be configured
for O.D., I.D., or odd form gripping with various jaw geometries.
The ER collet chuck also has a clear aperture for product feedthrough
and can support tubing diameters from 0.5 mm (0.020 inch) to 30
mm (1.18 inch).
Direct-Drive Technology
The LaserTurn® series utilizes direct-drive noncontact motor
and encoder technology for both the linear and rotary axes. Direct-drive
motors exhibit significantly higher throughput and maintenance-free
operation when compared to gear and screw-driven technology. Linear
and rotary encoders coupled directly to the load have the highest
level of system accuracy and repeatability over the operating
lifetime of the stage.
Scalable Product Solutions
Two platforms, the LaserTurn® 2 and the LaserTurn® 5, are
available to provide support for different price and performance
requirements. Each product features the automated material handling
capabilities and modular tooling platforms. The LaserTurn® 2 has a smaller overall footprint and reduced load carrying capability
while providing similar accuracy and repeatability to the larger
LaserTurn® 5.
The LaserTurn 5’s deeper cross section and larger
bearings provide higher throughput and dynamic tracking accuracy
for a given load when compared to the LaserTurn 2.
Advanced Control Architecture
The LaserTurn is available with Aerotech’s advanced
A3200 control system. The A3200 is a 100% digital system with
high performance FireWire® networked drives. With this fully
digital architecture it is possible to optimize the current, velocity,
and position servo loops for maximum performance. Advanced trajectory
generation capabilities such as multi-block look ahead minimize
geometry errors in tight profiles by transparently regulating
cutting speed. Aerotech’s Position Synchronized Laser Firing
Output (PSO) functionality automatically adjusts the laser pulse
frequency to match the current cutting speed to maintain optimal
laser power coupling.
