Precautions for Cutting Round Holes with an Laser Bridge Cutting Machine

Cutting circular holes with a laser bridge cutting machine is not as easy as imagined, so what details should be paid attention to?

Key Points:

1. Small Hole Diameter

Cutting 1:1 ratio holes is the optimal approach for an Laser Bridge Cutting Machine. The larger the hole diameter, the easier it is to cut. Machines with insufficient capability may encounter issues such as irregular hole shapes or excessive residue at breakpoints when cutting smaller holes.

2. Gas Pressure

Excessive gas pressure can cause blowouts, while insufficient pressure can result in rough and severely melted edges. Choosing the appropriate gas pressure is one way to address irregularities in round hole cutting.

3. Servo Motor Parameters

Many parameters of the servo motor are related to arc motion. If these parameters are not properly configured, mismatched movements of the X and Y axes may lead to elliptical or irregular hole shapes.

4. Precision of Screw Rods or Guide Rails

Some small manufacturers may lack technical expertise or skilled workers, resulting in laser cutting machines with precision levels below 0.1 mm. Consequently, the precision of the round holes they cut may also fail to meet requirements.
