The showstopper on the stand of Kerf Developments at the MACH 2024 exhibition in Birmingham, UK, earlier this year was undoubtedly the new Linc-Cut Fiber 1530A fibre laser cutter. According to Kerf, the machine offers dynamic kinematics, rigidity and precision.

Available as a 3, 6 or 12 kW machine initially with a 3 x 1.5 m or 4 x 2 m bed, the Linc-Cut Fiber 1530A synchronises laser cutting and axis movements to deliver accuracy, repeatability and speed. An auto-focus laser head with automatic gas and cutting height calibration delivers the necessary repeatability, while a compact laser source with fibre core diameter of 75 μm supports high cutting quality.

The new arrival also incorporates a CNC system that integrates with two surveillance cameras to control and monitor all machine operations. With drawing software and automated nesting, the control includes a database of parameters for all material types and thicknesses. The machine offers rapid axis movements of 110 m/min and positional accuracy of 0.03 mm.

Alongside the Linc-Cut Fiber 1530A at MACH was the new Kerf Ultra, a machine that provides both oxy-fuel and plasma cutting in a single machine. For existing customers of Kerf models, the new Ultra represents a technological leap forward that marks the arrival of next-generation profile cutting technology. With improved speed, precision, repeatability and cut quality over previous models, the new Ultra achieves elevated parameters by introducing a brand new motion system and new linear slide technology that sits upon an enhanced machine frame design.

BLM Group says that its Lasertube LT12 is not just a new laser cutting system, but a true convergence of technology and innovation. The goal of the new system is to fill a gap in the company’s Lasertube system offering, which manifested between two products: the LT8.20, which focuses on flexibility and performance, and the LT14, which is dedicated to processing long and heavy profiles.

The LT12 is a solution for processing tubes, profiles and beams, keeping the focus on versatility and productivity. Many times, customers have asked BLM Group for a product larger than LT8.20, but the jump to LT14 was too great both in terms of footprint and performance across the lower range. BLM created the LT12 to give customers the opportunity to process ‘light’ tubes with high performance, but also process larger tubes when necessary. Agricultural machinery is among the target sectors.

BLM Group sees great opportunities in agriculture since the size of square tubes, rectangles and even open profiles (including C, L and H profiles) in this industry are around 300 mm diameter – exactly the size range of the LT12. There are also many structural assemblies in agricultural machinery that would benefit significantly in terms of reduced manufacturing cost. Of course, the new product is also very interesting in light construction architecture, for making canopies or small sheds, with tubes or beams up to 6-8 mm thick and lengths typically longer than the traditional 6 m.

The machine concept is similar to the LT8.20, with a mandrel in the tail and a chuck to support the tube in the cutting zone. BLM Group’s LT12 has an interpenetrating mandrel in the chuck to help minimise scrap without the need for chuck or mandrel movement. The machine features a chain loading system for tubes from 8.5 to 12.5 m. Fully automatic unloading can reach a length of 12.5 m.
