Plasma Oxyfuel Cutters

Description

The LT Family of Laser Tube Cutting Systems have been designed specifically for laser tube cutting with the following advantages:

· No hard tooling to make, store, or maintain;

· Better accuracy and repeatability than mechanical cutoff methods;

· Quick and easy changeover from one tube type to another;

· Economic fabrication in smaller lot sizes;

· Fast and flexible part changes through program modifications only.

Automatic focus control will be implemented on the vertical axis. A nozzle assembly will be provided to deliver high-pressure shield gasses needed for clean-cutting and will have a crash protection mechanism.

An Alta84 Control has been developed specifically for laser applications, and includes a touch-screen operator panel with a Windows interface. This control has been developed with standard PC-based components for high reliability, low cost, and easy service. It will be used to run all system axes, provide the user interface, perform all machine I/O, and provide control of the laser.

Programming

Parts will be programmed with conventional G and M codes (RS274). Built-in features programs are provided as part of the Alta84 Control. Built-ins include end-profiling and internal cutouts. Ends can be profiled to intersect with other tubes of various diameters and angles, or flat plates. Internal cutouts include through holes for pins, slots, and other features.

A post-processor for Mastercam is available as an option.

Safety

This system is proposed as a CDRH class IV system. A CDRH Class I enclosure is available as an option. A CDRH report (required by FDA for laser products) will be submitted by <<>> before shipment. Circuit protection, wire gages, and wire colors have been designed according to NFPA 79 specifications. All wires and terminal positions are labeled and all wires are properly secured in wire-ways, wire ties, or by other means.

All panels that provide access to circuits at more than 50 volt potential are labeled and require a tool to gain access.

Optional Equipment

Non-round tube profiles
The LT family of Laser Tube Cutting Systems has the capacity to handle non-round tube profiles including rectangular, square and ob-round. This option includes:

- Software for corner tracking
- Special adapters to the chuck and steady rests
to accommodate rectangular tube profiles

Automated tube handling
An automatic tube feeding system will hold up to 8000 lbs of raw tube stock and feed them automatically into the tube cutter.

Postprocessor
A postprocessor for Mastercam is available as an option. This postprocessor will allow the direct generation of part programs from design programs such as SolidWorks or ProE.

Finished Part Management
Only finished parts up to 14” are provided for in the standard product. Parts longer than that must be supported on the outfeed side and either manually unloaded or provided for with an automatic unload option. The features and price of this option depends on the range of part sizes cut.

LC24 Laser Tube Cutoff System

Description

The proposed laser tube cutoff system will be comprised of a laser source, beam delivery optics, a high level controller, and tube handling equipment. It has been designed specifically for laser tube cutting so it has the following advantages:

· No hard tooling to make, store, or maintain;

· Quick and easy changeover from one tube type to another;

· Fabricate in smaller lot sizes;

· Fast and flexible part changes through program modifications only.

Beam delivery optics will be provided to circularly polarize the beam and deliver it to the focus lens. A manual, micrometer based, Z-axis adjuster will be provided for focus control and for different tube diameters. A nozzle assembly will be provided to deliver shield gasses needed for cutting and will have a crash protection mechanism.

An Alta84 Control, developed specifically for laser applications, is also included. This control will be used to provide the user interface, run all system axes, perform all auxiliary equipment control, and provide control of the laser.

Programming
Parts will be programmed with conventional G and M codes (RS274).

Safety
This system is proposed as a CDRH class IV system (i.e., no enclosure of the working area will be provided). A CDRH Class I enclosure is available as an option. A CDRH report (required by FDA for laser products) will be submitted by AltaMAR before shipment.

Circuit protection, wire gages, and wire colors have been designed according to NFPA 79 specifications. All wires and terminal positions are labeled and all wires are properly secured in wire-ways, wire ties, or by other means.

All panels that provide access to circuits at more than 50 volt potential are labeled and require a tool to gain access.
