Material procossing



KALE CNC offers high-power, industrial grade precision lasers for material processing.



Laser cutting is a mature industrial process with high flexibility, non-contact and stress free processes that produce finished parts right from the tool. Laser cutting is very precise, with excellent dimensional stability, very small heat affected zone, and narrow cut kerfs. Various technologies are used depending on the type of material to be cut.


Many materials like fabrics, plastic foils, and papers are processed on the fly using a reel to reel process. Applications may be found in the medical and food industry in the manufacturing of pouches for soups, coffee or beverages, but also in digital printing lines or production lines for grinding paper. Lasers are an established tool in these converting lines. Typical applications are cutting (incl. kiss cutting), scoring and drilling.


Lasers are commonly used for marking and engraving of materials. There are a wide range of applications in automotive, electronics/semiconductor, aerospace, medical, consumer product and food/beverage industry. Benefits of laser marking and engraving in comparison to other traditional marking technologies are multifold. The processes are non-tactile and do not induce mechanical stress. It is a very flexible, basically maintenance free process, and the results are very precise and sustainable marks on a large variety of materials. It is also low in consumable cost.

Laser marking uses the laser beam from a CO2 or from a DPSS laser is steered with a galvanometric scanner head. The mark is typically created by a vector based procedure which allows for the highest mark speeds. Flat field lenses focus the laser beam and make sure that the focal position is always in the same focal plane throughout the whole laser marking area. The focal length of the lens defines the size of the marking field.


In laser engraving, the laser beam is steered through a flying optic system. The focusing optic is moved in X- and Y- directions in a raster pattern across the engraving area. A large variety of materials can be marked or engraved using a laser. Different laser types are used depending on the material.
