The wear parts of a fiber laser cutting machine are key to keeping the equipment running steadily and reliably. How fast they wear out depends on the materials you’re cutting, process parameters (like power and speed), how often you use the machine, and how well you maintain it. Below is a breakdown of these parts by their core functional modules, with all the details you need:
This system sends the laser beam from the generator to the cutting head and focuses it—think of it as the "core light path" of the laser cutter. The wear parts here directly affect cutting precision and efficiency.
Wear Part Name | Core Function | Why They Wear Out | Signs It’s Time to Replace |
Focus Lens | Focuses the laser beam into a tiny spot to get the high energy density needed for cutting. | 1. Cutting smoke/spatter sticks to the lens surface, lowering energy reflectivity. | 1. Burrs on the cut edge or uneven cut surfaces. |
Protective Lens | Sits below the focus lens to block smoke and spatter from hitting the focus lens (it’s a "protective barrier"). | 1. Metal spatter hits the lens directly during high-frequency cutting. | 1. Obvious scratches, dents, or heavy stains on the protective lens. |
Collimator Lens | (On some machines) Straightens the laser beam into parallel light to keep the beam diameter stable during transmission. | 1. Dust gets into the collimator cavity if the light path isn’t sealed well. | 1. Larger laser spots and lower precision (e.g., rough edges on small holes). |
l Function: Guides the auxiliary gas to the cutting area at a specific angle (e.g., straight tube, diffused) to blow away molten slag and cool the cutting head.
l Wear Cause:
l The nozzle sits close to the workpiece—spatter hits it directly, causing deformation or cracks.
l High heat (especially when cutting thick plates) builds up slag inside the nozzle.
l Wear on the threads connecting the nozzle to the cutting head.
Replacement Sign: Deformation or gaps at the nozzle opening. Slag sticks to the cut (can’t be blown away). Uneven gas spray leads to diagonal lines on the cut surface.
By maintaining these wear parts properly, you’ll extend your fiber laser cutter’s lifespan, cut down on breakdowns, and keep cut quality consistent.
