Glass Cutting Applications:Comparative Analysis of Picosecond Lasers and CNC Machining 

To meet the growing demand for glass applications in daily life, secondary processing such as glass cutting and drilling is often required. Traditional methods of secondary processing typically fall short in terms of cost, precision, and efficiency. So, what advantages does laser technology offer when addressing these challenges?

CNC machining is a way to process the shape and contour of glass by using a drill. By changing drill bits of various specifications, different processes can be accomplished. However, this method requires water cooling for the drill bits and a cold water recovery system, and the drill bits need to be replaced periodically, leading to high costs. Additionally, the grinding process is time-consuming.

The application of lasers in glass cutting and drilling is more revolutionary. To meet various application needs while balancing cost, efficiency, and quality, laser source selection has become more refined.

HGTECH’s automatic Pico-second Single-head/Double-head Laser Cutting Machine is undoubtedly the optimal choice in the glass cutting field. This equipment utilizes picosecond laser cutting technology to perform full-sheet cutting on smartphone camera cover glass, replacing traditional CNC machining methods.

● Use the picosecond wire-cutting technology to “cut through” the material directly;

● Linear motor PSO control, micron-level precision, real-time path control synchronization to achieve “irregular shape cutting”；

● Equipped with CCD visual positioning, offset correction compensation;

● Customized automatic loading and unloading system, ergonomically designed.

In response to the vast potential of the glass cutting market, HGTECH is actively developing more ultrafast laser processing equipment. In the future, these ultrafast laser devices are expected to enable more precise processing with higher yield rates and lower energy consumption.
