• Configure for wet or dry cutting
• High-speed rotary option for rotational speeds up to 2000 rpm

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.

可伸缩的产品解决方案新万博最新版本

Two platforms, the LaserTurn2 and the LaserTurn5, are available to provide support for different price and performance requirements. Each product features the automated material handling capabilities and modular tooling platforms. The LaserTurn2 has a smaller overall footprint and reduced load carrying capability while providing similar accuracy and repeatability to the larger LaserTurn5.

The LaserTurn5’s deeper cross section and larger bearings provide higher throughput and dynamic tracking accuracy for a given load when compared to the LaserTurn2.

Advanced Control Architecture

The LaserTurn is available with Aerotech’s advancedA3200 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’sPosition Synchronized Laser Firing Output (PSO)functionality automatically adjusts the laser pulse frequency to match the current cutting speed to maintain optimal laser power coupling.
