Precautions for Cutting Round Holes with Metal Laser Cutting Machines

An increasing number of enterprises are adopting laser cutting for circular holes due to the flexibility and efficiency of laser processing. The 500W fiber laser cutter's idle speed of 60 meters per minute sufficiently meets the high-speed demands of many sheet metal workshops. Additionally, laser-cut circular holes feature smoother cross-sections, and their diameters can be infinitely adjusted to accommodate diverse factory requirements.

However, laser cutting circular holes is not straightforward and requires specific techniques. Below, engineers from Tor Laser analyze the causes and precautions for circular hole cutting issues.

I. Inappropriate Air Pressure

During the blowing process, insufficient pressure can cause edge slagging and carbonization, while excessive pressure may lead to hole bursting. This necessitates perfect coordination between the process prototyping engineer and the machine, relying on experience to select the appropriate pressure for fuller, more consistent circular holes.

II. Undersized Holes

The optimal solution for laser cutting machines involves a 1:1 hole-to-material thickness ratio. Naturally, larger holes facilitate higher-quality cutting. Otherwise, when fiber laser cutting machines lack sufficient energy, small holes may exhibit break points, residue, or non-circular shapes.

III. Incorrect Servo Motor Parameters

Elliptical or irregular holes sometimes result from mismatched XY-axis movements, directly caused by improper servo motor parameter adjustments. Thus, achieving high-quality circular holes also demands specific servo motor specifications.

IV. Precision Errors in Guide Rails and Lead Screws

While servo motor parameter errors impact cutting quality, precision deviations in guide rails and lead screws also directly compromise circular hole accuracy. This reflects the manufacturer's capabilities—some small factories may falsely claim 0.1mm precision, yet actual operation yields poor laser drilling quality and diminished product value. Thus, selecting reputable brands and high-quality laser cutting machines is essential.

All these parameters—used to evaluate whether circular hole cutting precision, speed, and other specifications meet standard requirements—sufficiently determine whether the purchased laser cutting machine meets quality standards. Thus, customers must be vigilant during the laser cutting machine procurement process.
