Trumpf will be showcasing a new laser cutting technique at its InTech in-house trade show, which will take place on 17-20 May in Ditzingen, Germany. Offering improved efficiency and even more reliable processing, the ‘nano joint’ method holds parts in place using tiny supporting tabs created at points where the laser does not cut all the way through the sheet. These tiny tabs, or nano joints, prevent the metal from shifting or tipping while the laser is cutting parts.

Nano joints reduce costs and material usage by allowing users to nest parts closer together and minimise how much metal remains in the skeleton. Depending on the shape of the specific parts, users may even be able to nest parts in a way that eliminates raw material waste completely. Nano joints also make it quicker and easier for workers to break parts out of the nest.

Trumpf offers nano joint technology on its TruLaser 5000 fiber, TruLaser 3000 fiber and TruLaser 1000 fiber series machines. Furthermore, it is possible to retrofit the technology to existing machines by means of a software update.

Currently, fabricators typically hold cut parts in place during laser cutting using tabs known as ‘micro joints’. Workers then break these tabs when they remove the parts from the nest. Trumpf says that its nano joints have many advantages over conventional micro joints. For instance, they speed up the process because it is so much faster to produce tiny retaining points rather than conventional micro tabs during cutting. Nano joints also allow the operator to break parts free from the nest with much less effort, saving time and making life easier for workers.

Nelson-based Pendle Engineering is a subcontract supplier of steelwork, a description that covers its main focus on tube and flat sheet manipulation, as well as turning, milling, welding, painting and design. Along the way the company has also branched into the manufacture of bicycle racks, trailers and storage products for its sister company, Pendle Bike Racks.

To meet business growth with improved efficiency, the company has invested in Elect 52 and E-Turn 32 tube benders, as well as a Laser Tube LT-Fiber Evo fibre-optic, fully automated laser tube cutting system, all supplied by BLM Group.

“Business has been increasing, especially with increased orders for Pendle bike racks, so we knew we had to upgrade our existing tube processing capacity,” says managing director Chris Smith. “We had a history with BLM for tube bending over many years so when it came to upgrading our 15 year-old tube laser it made sense to talk to them and put a bending and laser package together. A big advantage in doing that was the ability for the controls on the BLM benders and the Laser Tube to communicate with each other, while the ease of use of the BLM software and offline programming was also a significant factor. The less time a machine is idle the better.

“We’re already seeing the benefits of increased productivity, even though we’re not running at 100% yet with the BLM Laser Tube,” adds Smith. “It’s faster and the nesting capability brings a reduction in waste. Furthermore, we can cut more complex components, yet the operation of the machine and software is much simpler.”

Amada has launched its Ensis 6225AJ fibre laser cutting machine into the European market. With the ability to process 6.2 x 2.5 m sheets, the new machine is available in 6, 9 and 12 kW variants, with all powers able to cut up to 25 mm mild steel, stainless steel and aluminium.

Being able to process larger sheets, or multiple sheets in a large cutting area, leads to several benefits, such as more efficient material utilisation and higher production flexibility. Previously, Amada Ensis fibre lasers were available in 3 x 1.5 m and 4 x 2 m variants. Now, the series has been expanded to incorporate 6.2 x 2.5 m capabilities.

Utilising Amada’s established variable beam control technology, first released in 2014, the Ensis 6225AJ automatically adapts the laser beam mode (not just the focal position and spot size) to each material and thickness combination. This technology also allows the beam mode to be changed between the pierce and the cut, providing a high-power density beam shape for high-speed piercing, then instantly changing to the optimal beam shape for providing high-speed, high-quality cutting. Notably, a single lens can process all materials and thicknesses.

Amada has also added several new laser integration system features to the Ensis 6225AJ that provide more autonomous functionality, rather than relying on the operator to carry out certain checks.

For instance, the i-Nozzle Checker automatically checks the nozzle condition and changes it in conjunction with the standard 16-station nozzle changer if damage is detected, thereby removing any subjective operator decision. This system also incorporates automatic beam to nozzle alignment, significantly reducing start-up times and processing issues.
