Picosecond Laser Uses Cold Processing to Add Precision
IMTS 2018: Trumpf’s TruMicro 2000 is a picosecond laser for applications including metal engraving, cutting thin films, and corrosion-free marking.
Trumpf’s TruMicro 2000 is a picosecond laser for applications including metal engraving, cutting thin films, and corrosion-free marking of medical instruments and chrome-plated plastics. It emits short laser pulses ranging from 0.4 to 20 picoseconds and has a peak power of 20 microjoules. This enables the laser to perform cold processing, meaning it performs the task before the material begins to register a thermal process. This is said to reduce the occurrence of undesirable thermal effects such as micro-fissures and residual melt, enabling precise applications including smooth surfaces and deep black markings.
The laser can accomplish microprocessing applications such as structuring, cutting and ablation. A “Pulse on Demand” feature applies the laser pulse to a desired location with micrometer accuracy, enabling precise work on a variety of materials. The laser also has a double power regulation that enables the operator to precisely set the power from pulse to pulse.
At first, abrasive waterjet machines were naturally at home in the fabricating shop. Today, certain models resemble a typical, fully enclosed CNC machine and they fit well in a machining job shop setting.
Machine with abrasive waterjet and control the depth of cut. For the right parts, this fledgling process may offer a compelling alternative.
Waterjet cutting has carved a legitimate niche in material fabrication. This article looks at the process with an eye toward how waterjet can work for your shop.
