LSM 400 Laser Welding Machine Sets New Standards in Diamond Tool Production

Published: 30/12, 2022

With the new LSM 400, saw blade laser welding machine Dr. Fritsch strengthens its position as the world market leader in the diamond tool

industry.

In 1989, when Dr. Fritsch launched the first laser welding machine LSM 800, the rather conservative industry was admittedly quite skeptical. Up to that that point, brazing had been the common method of attaching segments to the blade. Dr. Fritsch, however, continuously developed the laser technology and launched the second generation of innovative laser welding machines in 1998. Almost 100 units of the LSM 240 were sold and many of them are still in daily use at our customers. The next development step was the LSM 300, introduced in 2009. This machine impressed the industry with its robustness and several new features.

Now, Dr. Fritsch’s new LSM 400 saw blade laser welding machine replaces the previous LSM 300 generation and sets new standards throughout the industry in terms of increased productivity as well as process and cost efficiency. Combined with a line scanner, the LSM 400 ensures penetration depths of up to .25 in (6 mm, resulting in a significantly better connection between segment and blade as well as a visually more attractive welding seam.

Inside the machine up to four cameras ensure precise monitoring of the machine interior. Two of them are used to check the welding seam on the screen. Set-up times are significantly reduced when changing over to other segment shapes. Accessibility of the machine is optimal in all areas, especially for segment feeding and blade loading at the front.

Developed in close cooperation with Diamond Tools Austria, the LSM 400 can accommodate blade diameters of up to 78.7 in (2,000mm), expanding segment heights and thicknesses as well. It’s also possible to select a specific side clearance for each individual segment.

Thanks to the LSM 400’s new and intelligent programming, the operator saves valuable time during set-up. With optional motorized setting aids, infeed belts are controlled fully automatically, which saves time and prevents operator mistakes. The new programming also performs an automatic calculation of the helical welding path, suggests pre-set parameters, depending on tool dimensions, or assists with the parameter set creation. The graphic panel ensures maximum clarity of operation. Optimally placed protection and suction systems have reduced process-related dirt and fumes to a minimum. Other features include a modular design that enables Dr. Fritsch to respond to individual customer requirements and the energy efficiency of the fiber laser technology.

With the development of the LSM 400 and its advanced features Dr. Fritsch is well prepared to meet the requirements of the construction and stone industry.
