LM-B

SEMI-AUTOMATIC LASER WELDING SYSTEM
LM-B is a semi-automatic laser system for welding small objects, for example in the medical field or for mold repair. Comfortable and quiet, it is equipped with an Nd:YAG laser (Flash lamp) that offers a wide depth of field and stable firing from the very first pulses, for consistent welding quality (Smart Spot technology) even for extremely thin beads (Nano Spot; diameter up to 0.05 mm).

This machine is suitable for:

For different types of parts, processes, or workable materials.

Vision version with Syncro View

LMC: manual or programmable CNC axis movement

SPEED AND PRECISION

The 3 motorized axes and the optional spindle ensure precision, speed of execution, and repeatability.
The operator enjoys maximum freedom of action when alternating between semi-automatic and manual operations.
The software managing the processing parameters, developed by Sisma, allows for welding along linear and/or circular paths, managing recipes, and optimizing welding yield by modulating laser power at the start and end of the process.
The upper part of the machine can be rotated to facilitate workpiece loading.
