More sustainability in laser cutting
With the new Nanojoints technology, components can be nested directly next to each other on the metal sheet. Users save time and material with greater process reliability. Mini-joints generally make reworking superfluous.
The machine tool manufacturer Trumpf has developed a new process for greater efficiency and process reliability in laser cutting, which will be presented to the public for the first time in May at the in-house trade fair "Intech". The nanojoint process involves tiny holding points at which the laser does not completely cut through the sheet metal during cutting. The nanojoints ensure that the components do not tilt while the laser is cutting them out.
"With our nanojoints, users can improve process reliability in laser cutting and make several work steps more efficient. The solution is an example of how Trumpf has mastered the entire sheet metal process chain and offers every customer solutions to improve their production," says Patrick Schüle, Product Manager at Trumpf.
With the nanojoints, users save material and costs as the parts can be nested more tightly. Depending on the shape of the components, users can even nest without residual skeleton. In addition, employees can remove the cut parts from the cut sheet much more quickly and easily. Trumpf offers nanojoints on its laser cutting machines from the TruLaser 5000 fiber, TruLaser 3000 fiber and TruLaser 1000 fiber series. The process can be retrofitted with a software update.
Higher process speed, less rework
Until now, bars were needed to hold the sheet metal in place during cutting - so-called "microjoints". The employee breaks off these bars when he picks up the components. Nanojoints have many advantages over conventional microjoints. The process speed is increased as the mini-joints can be produced much faster during cutting than conventional bars.
The employee hardly needs to exert any force to remove parts with Nanojoints. This saves time and relieves the strain on production staff. Manual reworking is also usually completely eliminated, as the nanojoints only leave a barely visible mark when separating the components. Microjoints, on the other hand, leave a larger contour mark, which the employee then has to remove manually.
