The LaserTurn® 1 cylindrical laser machining system
supports material from 0.1 mm to 7.9 mm in diameter, making it
an ideal platform for the manufacture of cardiovascular and neural
stents. The system can be configured for wet or dry cutting and
includes options for material advance and bushing alignment platforms.
The integrated linear-rotary system combines automated material
handling functionality with high performance direct-drive linear
and rotary motion.
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.
Automated Material Handling
The LaserTurn 1 is a complete motion and material handling subsystem.
The system includes an automated, pneumatically activated Type
D collet closer. The collet closer has a clear aperture for product
feed through and can support tubing diameters from 0.1 mm (0.0039
in) to 7.9 mm (0.3125 in) in dry cutting applications and up to
3 mm (0.118 in) 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.
Direct-Drive Technology
The LaserTurn 1 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.
Noncontacting Labyrinth Cover Design
The overlapping hard cover design protects the linear stage of
the LaserTurn 1 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. 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.
