Laser Cutting Tips: Mastering High-Precision Countersinking

Countersunk holes are traditionally machined by two main methods: drill cutting and press stamping. Drill cutting requires experienced staff to operate, and for tapered countersunk holes, the holes need to be further machined on the basis of flat bottom countersunk holes. Punching, on the other hand, is performed on sheet metal parts by mounting a die on a universal or CNC punch press. These Traditional methods, though widely used, fall short when high precision and complex materials are involved. For Example：

1). Bolt is raised when put in

2). Requires secondary processing

3). Waste of time and labor cost

So, how can manufacturers achieve stable, high-efficiency countersinking operations, especially for demanding materials?

1. The Laser Countersinking Revolution: Why It’s Superior

• Precision & Control

Laser countersinking provides unmatched precision, allowing intricate adjustments to achieve micron-level accuracy. Unlike mechanical methods, lasers produce consistent results, even on complex geometries and tough materials, eliminating issues like drill wander or uneven surfaces.

• Efficiency Boost

Laser countersinking dramatically reduces processing time. Without tool contact, each hole can be precisely countersunk in as little as 0.2 seconds. Batch processing and array-hole formation further amplify productivity, enabling mass production without sacrificing quality.

• Cost Savings

Lasers minimize tool changes, reduce defect rates, and eliminate the need for subsequent polishing. Overall, this leads to a significant cost reduction.

•  Environmental & Safety Benefits

Laser countersinking is environmentally friendly, producing no harmful dust or debris and significantly reducing noise pollution. It's also safer for operators, with minimal physical risk compared to mechanical methods.

2. Detailed Breakdown: Bodor Laser Countersinking Process

Bodor Laser’s advanced countersinking process is specifically designed for high-precision machining tasks, ensuring consistent quality, accuracy, and efficiency. By carefully managing critical parameters and utilizing innovative laser technology, Bodor Laser provides a comprehensive solution structured into three stages:

(1) Basic Graphic Design

Measurement: Accurately measure the diameter of the intended screw or bolt.

Design Preparation: Utilize software to create an exact circular cutting path, inputting the radius based on the measured diameter.

Guideline Setup: Configure countersinking parameters, including the number of cutting passes, spacing between circles, and the preferred cutting direction.

(2) Cutting Parameter Configuration

Tailor settings to match the thickness of the material and specific project requirements;

Countersink Parameters: Set both pre-operation and post-operation delays to zero to prevent overheating. Adjust the peak power based on desired depth

(3) Laser Countersinking Execution

Initial Hole Cutting: Precisely cut a round hole matching the stud's diameter to ensure proper alignment.

Pre-Cutting for Nut Space: Conduct a preliminary sweeping cut slightly smaller than the final nut diameter to provide adequate installation space without material deformation.

Final Precision Countersink: Perform a finishing sweep cut precisely matching the nut diameter, ensuring accuracy and optimal fitting.

Following these structured steps ensures consistent quality, accuracy, and functionality in laser-cut countersunk holes.
