Laser Hardening System, Type LHS

Our Laser System LHS is designed to harden steel parts and hand tools at a high repeatability and allowes to create very distinct hardening profiles. The stressed regions can be processed very precisely, while the rest of the tool remains unaffected. 

Core of this system are two diode lasers that work independently to achieve high production rates. The laser heads are mounted onto a four axis driving system. A vision system takes the shape of the product and calculates the working way for the lasers. A set of parameters allows you to set up the hardening procedure like the start point, endpoint, speed and power. These parameters are stored in a setup file, independently for each type. During the hardening procedure, the temperature is measured and displayed. Two curves show the peak power as well as the average to monitor the process. The system is controlled by a high integrated machine control system combined with a PC.

Laser Trimming System For Inductors, Type LWS

SMD-Inductors of the size 0603 in laser cut technologie are produced with the Laser Cutting System LWS.

The Laser Cutting System LWS is a production system for SMD-Inductors, size 0603. A laser beam cuts a spiral into the rotating raw part, which is a copper plated ceramic body. To produce different coils, for each type a set of parameters is generated. After choosing the type, the machine does an automatic setup. The System can produce inductors from 1,5nH to 220nH and works with kerf widths of 20µm and lower.The machine has two working heads for a maximum output. With a camera system, which is installed directly to the laser outlet, you can watch the production and set up the cut position. 

Laser Trimming System For Resistors, Type LSS

Melf-, Minimelf- and Micromelf-resistors are trimmed by the Laser Trimming System LSS at highest speed and nearest tolerance.

The components are fed out of bulk by a vibratory bowl feeder to a horizontal feeder. This feeder has a vacuum nozzle installed and inserts the components between the chucks. The feeder moves back and the components are spiralled by a high precision beam. After finishing this process, the components are sorted into the good and the reject box. A microprocessor unit controls the production. With a camera system, which is installed directly to the laser outlet, you can watch the production. The system makes it easy to set up the cutting length and the start and stop position of the laser. An automatic setup program calculates the optimized speed of the galvanometer. The System can produce resistors with final values of 0,1Ω to 10MΩ.
