Now Available in North America: Laser Blanking System for Flexible, High-volume Cutting
One of the latest advancements in precision sheet metal fabrication and applications from high-tech company TRUMPF (Farmington, CT) is the TruLaser 8000 Coil Edition, a laser blanking solution designed to boost efficiency and manufacture more sustainably. The TruLaser 8000 Coil Edition can process up to 25 tons of coiled sheet metal from start to finish without any human intervention. It is an attractive option for companies interested in flexible, high-volume solutions for sheet metal fabrication, including automotive suppliers and automakers, electrical cabinet manufacturers, elevator producers, and HVAC manufacturers.
“Compared to conventional laser cutting, the TruLaser 8000 Coil Edition can save up to 1,700 tons of steel a year, which reduces carbon emissions and material costs,” said Grant Fergusson, TRUMPF Inc.’s product manager for TruLaser 2D laser cutting machinery. “The system helps customers with high volumes of medium to large parts improve material utilization and produce more flexibly and sustainably.”
TRUMPF’s new laser blanking system helps companies enjoy the benefits of laser processing, even in high-volume production environments. “Volume manufacturers often use die presses for blanking operations but any modification to these components requires adjusting or even replacing tools, which ultimately costs time and money,” Fergusson added. “Today, many industries are seeing significant reductions in the scale of individual production runs, which makes modifications even more costly and time intensive. The laser allows users to carry out such modifications without another tool, so it’s much easier, faster, cheaper and flexible.”
Coil production enables users to achieve more efficient nesting of parts. Conventional sheets are limited by their four outer edges, which often makes it difficult for production workers to make full use of the entire sheet. Unused sections of the sheet either must be discarded as scrap or melted down. A coil solves this problem by allowing users to nest an almost endless number of parts on the sheet, which reduces material consumption by around 15%.
Compared to conventional 2D laser machines, material flow is different and leads to lower cycle times and new automation opportunities in high-volume production series. The system is designed for thin sheet processing, can handle sheet thicknesses of up to 0.25”, and can be flexibly adapted to any contours.
The production system is fully automated. An innovative system for transporting sheet metal during cutting keeps the material moving quickly through the whole process, with impressive gains in productivity. The new system also incorporates a TruLaser 3040 with TruDisk 8001 and uses many of the tried-and-tested features for which TRUMPF is renowned, including Smart Collision Prevention, which prevents cut parts from tilting and damaging the laser cutting head. The system includes technologies such as EdgeLine Bevel to enable chamfering, and Smart Rerun to save uptime while cutting with reentry techniques.
MMS Software Helps Manufacturers Optimize Their Sustainability Efforts
Fastems (West Chester Township, OH) announces a new version MMS 8.2, the software that controls Fastems’ automation systems, and which helps CNC manufacturers utilize automation to measure, report, and optimize their production sustainability efforts. Users can measure the energy consumption of their NC programs, minimize power usage during machine idle times, and dedicate specific machine tools to process certain metals for high-quality chip recycling. MMS version 8.2 will be available as a new feature and as an upgrade to existing Fastems automation systems beginning this summer.
CNC manufacturers all over the world are looking for ways to measure, report and optimize their sustainability efforts as the demand for sustainability grows. MMS version 8.2 automation control software is developed to help manufacturers in achieving their sustainability goals, especially in the area of high-mix manufacturing.
One of the most important requirements for a manufacturer is to begin measuring and reporting the carbon footprint of their produced parts. MMS 8.2 measures and reports the machine tool energy consumption of each NC program, allowing the manufacturers to calculate the energy usage in part level. The information can also be used to adjust the inefficient NC programs, or running certain parts overnight when the electricity demand is lower.
To minimize unnecessary energy usage, the new “Auto-Power On/Off” function turns machine tools off automatically when there are no planned NC programs to run. With the automatic wake function, the machine starts and warms up before the next NC program start time.
Because metal is a non-renewable and valuable resource, recycling is extremely important to sustainability efforts. MMS 8.2 comes with a material-dedicated feature that allows users to route jobs with specific material to specific machine tools. This way, high-quality chips can be easily separated and recycled.
