Motoman Robot Laser Cutting Contoured Panels

Motoman LaserWorld solution featuring CO2 laser, beam delivery system, Class 4 safety package.

Summary

Laser process eliminates costly set-up dies. Cycle time: 46 seconds; more than 23% faster than required 60-second cycle.

Cost-effectively cut narrow slot(s) in powder-coated panels on part contours where conventional die cutting and stamping methods would be difficult.
Provide flexible solution and flexible tooling/fixturing that can be easily adapted to handle future part design changes.
Achieve cycle time of one part per minute (production rate of 60 parts/hour).
Maintain tight part tolerances of ± .76 mm (.030").
Eliminate costly dies and die set-up time.
