Laser protection measures for fiber laser cutting machine

The laser used for cutting by fiber laser cutting machine is an invisible class 4 laser, and the radiation produced is less than 0.04mm. The depth of the feeler gauge should not be greater than 1/4 of the width of the contact surface, and the contact surface can be inserted The cumulative length of the feeler gauge should not be greater than 1/10 of the circumference. Safety and protection may cause danger to personnel, and the safety protection device should comply with relevant regulations. Protection against the danger of laser radiation During production (regardless of normal or not), the possibility of personnel being exposed to laser radiation should be excluded.

During maintenance of the fiber laser cutting machine, personnel should be prevented from being injured. During normal production, there should be one or more protective devices to prevent personnel from entering the processing area. During maintenance, people sometimes inevitably approach the laser radiation area. At this time, according to the following conditions, when performing maintenance in the dangerous area, use the same method as during production to control access (such as an interlocking protective cover). Protection during training, planning, and program verification. Personnel should be prevented from approaching the laser radiation area during training, planning, and program verification. If this condition cannot be met, it should comply with (a) the fixation of the optical fiber: prevent dragging and excessive bending; (b) the optical fiber may be damaged due to factors such as mechanical force and heat, and protective and alarm measures should be provided. The safety requirements of the control system should meet the relevant regulations of GB5226.1.
