Why burrs appear after laser cutting
Laser cutting can leave sharp edges, small burrs, slag and oxide skin depending on material, gas, power, speed and plate thickness. These issues slow down welding, coating and assembly if they are not controlled early.
Manual grinding vs automatic sanding
Manual grinding works for repair work and small batches, but it is hard to keep every edge and surface consistent. Automatic sanding machines feed parts through abrasive stations, which improves repeatability and reduces operator fatigue.
Recommended process
- Check burr height, slag hardness and required surface.
- Choose deburring, brushing, edge rounding or flat grinding stations.
- Run sample parts before confirming the final machine configuration.
- Add dust collection when processing carbon steel, stainless steel or aluminum in batches.
When to choose a sanding machine
If your factory processes laser-cut parts every day, an automatic sanding machine can reduce rework, improve downstream coating quality and make quotation lead time more predictable.
