CNC glass machining

CNC machining : Advanced technology for glass cutting and processing

Glass cutting is a key technology in the glass industry. Used in a wide variety of sectors, including industry, architecture and decoration, CNC transforms raw glass into finely cut pieces, perfectly adapted to the specific needs of each project.

CNC precision and capacity

One of its main advantages is its ability to cut complex geometric shapes with millimetric precision. CNC machines are capable of producing clean cuts, from simple edges to more elaborate shapes with specific notches. This process is ideal for projects requiring very tight tolerances, guaranteeing even edges and smooth finishes.

The CNC machine is able to work on glass of large dimensions, up to 3.60 m long and 2.20 m wide, with thicknesses ranging from 4 mm to 19 mm. The maximum weight of glass that can be handled is 205 kg. This flexibility makes it possible to adapt cuttings to the specific requirements of each project, from small decorative pieces to large sheets of glass.

CNC machining processes and Applications

The process allows not only precise cuts, but also a wide range of edge finishing options, from clear to matt polished. We can guarantee that the edges of your glass pieces will meet the most stringent requirements in terms of aesthetics and safety.

We also use CNC to produce other types of complex cut-outs, such as false squares. This type of cutting is frequently used in architectural and industrial applications requiring unconventional shapes and angles.

For interior cut-outs, here’s an example of how it works: work begins by drilling a central hole to allow the cutting tool to be inserted. A first cut is then made, leaving a border of 4 to 5 mm. This edge is then refined in successive stages to achieve optimum results. Finally, careful polishing is carried out to ensure a smooth, transparent edge (depending on the type of polish required).

CNC is also suitable for projects requiring customized notches, such as those required for fasteners or assembly systems. This process is used before the tempering or assembly stages for laminated or thermos (insulated) glass, as it is impossible to make cuts once these treatments have been carried out.

Notches: Glass ready for hardware

As previously stated, when manufacturing custom glass, notches can be made to accommodate the hardware required for installation. Very useful for showers, glass doors or stair railings. We are also able to supply certain types of hardware, such as “spigots” for tempered glass handrails, offering a turnkey solution. This process is often carried out via CNC or Waterjet, depending on the type of notch or hole required.

Thanks to this process, it is possible to process glass parts rapidly while respecting the technical specifications of your project, guaranteeing reliable and repeatable cuts on large volumes. This enables us to meet the requirements of the industrial, architectural and decorative sectors, offering a wide range of cutting solutions, whatever the shape or size of the glass.
