Laser blanking

Laser cutting from coil is becoming increasingly important in numerous sheet metal processing industries – both for large manufacturers and job shops with medium to large lot sizes. But what exactly is laser blanking, and how can you also benefit from the highly productive, flexible coil system from TRUMPF?

What is laser blanking?

The range of variants is increasing, production sizes are decreasing: This is exactly where the TruLaser 8000 Coil Edition from TRUMPF comes into play. Sheet metal processors often use press lines for large series sheet metal processing, but have to manufacture bending tools for each new product variant: an expensive and time-consuming process. Processing with a laser directly from the coil saves time, costs and material. However, users of conventional 2D laser cutting machines also benefit from processing rolled-up sheets. In addition to higher material utilisation thanks to tighter nesting and cost savings when purchasing coil material, the productivity benefits of laser coil processing are impressive. 

Laser cutting directly from the coil: The advantages

Efficiently produce small to large series

Whether you are a sheet metal processor job shop with larger lot sizes or a large manufacturer: anywhere that press lines constitute too large an investment and offer too little flexibility, but 2D laser cutting machines lack productivity, laser blanking offers simple, fast and economical production.

Save material costs

Save up to 15% in costs when procuring material compared to sheet goods. At the same time, benefit from up to 15% higher material utilisation thanks to more efficient nesting.

Produce flexibly

Compared to a press line, changes to the produced geometry are flexible and easy to implement. Using the laser as a tool entirely eliminates the cost of bending tools, maintenance, storage and setup operations.

Fully automate the cutting process

With the TruLaser 8000 Coil Edition, you can fully automate the cutting process – from unwinding the coil and flattening the sheet metal strip to robot-based component removal and sorting. The system fulfils all the tasks of a fully automatic cutting centre.

Connect to automated storage

The highly productive, highly automated laser blanking system can be flexibly connected to storage systems. Finished cut parts can be transported to other connected machines, for example for automated part bending.

Optimise further with intuitive software

TRUMPF TruTops Boost software suggests optimal nesting and separating cut strategies. This means you can depend on the highest possible material utilisation and efficient scrap management. Thanks to the software, components do not get caught in the scrap skeleton during removal. This increases process reliability.

These industries particularly benefit from laser blanking

Continuous adaptation of components, an increasing range of variants and the accompanying constant tool changes: this situation is now part of everyday work, and not only in the automotive industry. In many industries, there is also a trend towards smaller lot sizes. That's why TRUMPF experts have developed a solution enabling more and more industries to economically process sheet metal despite smaller lot sizes.

Automotive industry

Automotive

From the B-pillar to the battery tray: tool-free laser blanking systems bring considerably more flexibility to automotive production thanks to free contour programming. This results in decisive cost savings.

Agriculture

From tractor cabs to metal plows, the agricultural sector also stands to gain from the many advantages of laser blanking.

Stainless steel furnishings

Stainless steel components for kitchens can be manufactured with the highest surface quality as well as quality and accuracy requirements.

Trains

Long panel and frame parts for trains are ideal for laser blanking.

Electrical cabinet construction

Door, frame and sliding parts for electrical cabinet construction in large series can be produced cost-effectively with laser blanking systems.

What does a laser blanking system look like?

The TruLaser 8000 Coil Edition by TRUMPF is the highly productive, flexible laser blanking system for continuous cutting of coil material. Equipped with an ARKU precision leveller, the ARKU belt system and TRUMPF laser combine for an entire turnkey system with many advantages for customers. Together with SIEMENS, an innovative control system has been developed – from coil unfolding, levelling, and laser cutting to fully integrated, robot-based component removal. The entire system programming up to robot removal is done by TruTops Boost.

6. Scrap disposal

Small separating cuts are already made in the scrap skeleton during the cutting process. The scrap skeleton can then simply be disposed of.

Decoiler

With short setup times and high availability, you benefit from high efficiency over the entire system service life. The system is characterised by compact design, high speeds, higher process reliability, and short coil changing times. Laser cuts can be optimally nested on strip material, reducing scrap. This saves you up to 15% on material costs. Whether steel, stainless steel or aluminium – many different materials can be processed. Coils up to 20 t can be accommodated as standard, 25 t and a width of 2150 mm are possible as options.

Precision levelling system

The CoilMaster 50 precision leveller from ARKU delivers consistently good levelling results for robust laser cutting. Coil material from 0 up to 4 mm in thickness is supported as standard, whether steel, stainless steel or aluminium. Even higher-strength steels can be processed with the nine levelling rollers. During roller levelling, the coil material passes through alternating bends, flattening it and relieving tension. The component can then be cut safely and then removed from the scrap skeleton.

Strip storage loop

The hydraulically controlled strip storage bridge supplies the laser cutting cell with material, decoupling the material feed cutting process and the strip system. The belt speed in the strip system is reduced to a minimum, but never stopped. This avoids the risk of surface damage to the strip. The strip feed rollers integrated in the strip storage transport the strip material to the laser cutting cell at up to 40 m per minute. 

TruLaser cutting cell with TruDisk, including conveyor belt

The heart of the laser blanking system is a proven TruLaser cutting machine. The coil material is transported linearly through the machine, reducing non-productive times by a factor of up to 2.5. This is made possible by a support belt newly developed by TRUMPF. While the new material is transported in, the processed material – including scrap – simultaneously moves out. This increases the entire system productivity many times over.

Automated robot unloading

One or, optionally, two robots enable parallel to production unloading and repeatable stacking. The complete integration of the robot kinematics into the control architecture eliminates the need for robot-specific programming expertise. The position of the components is already determined during programming or nesting of the cutting parts in TruTops Boost. This way, the robot immediately knows where the components to be removed are located.

Scrap disposal

Small separating cuts are already made in the scrap skeleton during the cutting process. In this way, the scrap skeleton breaks into smaller pieces during removal and can be disposed of in a cost-efficient manner. The scrap conveyor can transport scrap out of the machine in three directions as required - either directly out or via a transverse conveyor belt to the left or right. This way, scrap removal can be integrated into the customer's scrap logistics.
