The LaserTurn® 1 is an integrated
linear-rotary motion subsystem that combines automated material handling with
high performance direct-drive linear and rotary motion to provide the highest
throughput, highest accuracy, cylindrical laser processing system available.
Automated Material Handling
The LaserTurn 1 is a complete motion and material handling subsystem. The system
includes an automated, pneumatically actuated Type D collet closer. The collet
closer has a clear aperture for product feed-through and can support tubing
diameters from 0.1 mm to 7.9 mm in dry cutting applications, and up to 3 mm
when configured for wet cutting operation. The collet closer is designed to
minimize axial tube motion during clamping operations by keeping the collet
stationary and moving the tapered mating surface during collet open/close operation.
Integral Tooling Platform
The LaserTurn 1 includes standard front and rear tooling platforms with M4 mounting
features. The tooling platforms are bolted directly to the base of the linear
stage providing a stiff, monolithic, common inertial frame of reference. Fixtures
such as bushing alignment assemblies, part collection, or automated material
advance functions can be attached easily.
Direct-Drive Technology
The LaserTurn 1 uses 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
technologies. Linear and rotary encoders coupled directly to the load provide
the highest level of system accuracy and repeatability over the operating lifetime
of the stage.
Noncontact Labyrinth Cover
Design
The overlapping hard cover design protects the LaserTurn 1 linear stage from
contact with fluids used in wet cutting processes. The sloped hard covers provide
robust protection from fluid and machining byproduct ingress as well as incidental
operator contact that may occur during part changeover.
Advanced Control Architecture
The LaserTurn 1 is available with Aerotech's advanced A3200 control system.
The A3200 is a 100% digital system with high performance FireWire® networked
drives. The A3200's digital architecture makes it 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) feature automatically adjusts the laser
pulse frequency to match the current cutting speed to maintain optimal laser
power coupling.
