KMLT® specializes in high-precision laser cutting with extremely low burr formation.
Our special machinery is predestined for the production of precision parts from almost all possible metals, precious metals and alloys in material thicknesses from 0.005 mm to 3.0 mm.
Depending on the part geometry and material properties, production tolerances of up to ±3 µm can be achieved. These can be verified by a measurement report.
The main customers for our laser work include microelectronics/electronics, optical and precision engineering, medical technology, the watch and luxury goods industry, precision mechanical engineering, the automotive sector and research and development.
We supply parts for mechanical watches, spring elements, shielding plates, calibration masks, fitting rings, shims and precision raw parts of all kinds, both as single parts as well as in large batches.
Laser Micro Cutting
Sheet metal processing
For the high-precision cutting of thin metal sheets and metal foils, we have a range of selected systems with fiber and diode lasers at our disposal.
The achievable manufacturing tolerances correlate with the size of the work surface, the type of material and the material thickness.
The smallest cutting gaps of approx. 15 µm with minimum web widths of 20 µm show our first-class micromachining capabilities.

Tube processing
Several of our laser systems are also equipped with motorized rotary axes for processing tube bars.
Pipe profiles can be provided with apertures around the circumference and cut to size.
The cut edges and surfaces can be deburred and matt-finished by glass bead blasting.
Our micropolishing system is suitable for the smallest parts.
