BALLIU NV Machine Tool Corporation – COMPANY PROFILE

Founded in 1894 in Gent, Belgium, BALLIU MTC nv quickly gained a good reputation in the machine engineering business. In the beginning of the 1970’s, with the emerging commercial applications of LASER technology, we focused on developing the first LASER equipped machines for the industry. In 1998 we moved to our newly build 10000m² production facility in Lokeren. In 2003 BALLIU MTC nv joined the OGEPAR-group, a financially strong holding of company’s, several of them in the machine manufacturing business.

Today, BALLIU MTC nv is a sound, export-oriented (more than 90%) company with a extensive sales- and service organisation. Our sole business is developing and manufacturing LASER-equipped machines for all kinds of applications and materials, whether it is a titanium wire frame for sunglasses or the turbine of a jet engine. We broadened our specialities from laser cutting to laser welding and cladding. We have a complete range of standard products for laser-cutting, welding and cladding, with or without automatic loading- and unloading equipment. Our ability to integrate and adapt our machines to our clients’ needs is the base of our success.


Cladding

The choice of the laser and its power is important when choosing a cladding machine. A laser must generate enough power per square millimeter to melt the cladding powder onto the metal surface. The higher the laserpower, the bigger the cladding spot and the faster the production process. CO2-lasers and diode-laser are commonly used for cladding. The pro’s and con’s of both types of laser are listed below.

Diode laser

  • More efficient
  • Fiber link between laser and cladding head
  • Limited warming of fiber
  • Heat distribution in spot is evenly divided
  • Ability to change focus limited
  • Compact housing
  • Limited Power: currently 8 kW

CO2 laser

  • Less efficient
  • Beam path with mirrors
  • Cooling of optical way
  • Non homogeneous energy distribution in the spot
  • Ability to focus is easier
  • Larger housing
