At AMB 2026 in Stuttgart, Kellenberger will present hard turning, universal grinding and digital machine simulation. The SP42 hard-turning machine, K100 cylindrical grinder and TM300 Digital Twin address a shared production challenge. They combine machining quality with productivity, flexibility and reliable digital processes.
The machines and software target applications in aerospace, automotive, e-mobility, medical technology, energy, tool and die making, and general mechanical engineering. Kellenberger will focus on integrated manufacturing concepts rather than individual machine functions. These concepts include turning and grinding in one setup. They also include flexible grinding machine configurations and virtual validation of machining operations. Manufacturers can therefore shorten setup and development work while improving process stability. Developed with Siemens technology, the TM300 Digital Twin will be shown at AMB for the first time as a fully integrated virtual model of the turn-mill centre.
Digital validation for the TM300
The KELLENBERGER TM300 is a five-axis turn-mill centre for general mechanical engineering, aerospace, medical technology and high-accuracy engineering. It combines turning and milling on one platform. Its main and counter spindles reach speeds of up to 3,500 rpm and deliver 600 Nm of torque. The milling spindle provides up to 12,000 rpm and 100 Nm of torque. A direct-drive B-axis offers a swivel range of 240 degrees. An orthogonal Y-axis provides 300 mm of travel. Together, these features extend the available machining envelope. The machine brings complex turning, milling and complete machining operations into one process chain.
At AMB, however, the physical machine will be complemented by a digital representation. The TM300 Digital Twin replicates the machine’s kinematics, machining processes and CNC control functions. It allows operations to be simulated, optimised and validated before machining begins. According to Kellenberger, this can reduce development time and lower process risks. It can also accelerate machine commissioning. The presentation reflects the growing role of virtual commissioning and connected manufacturing in machine tool applications.
Hard turning and grinding in one setup
The KELLENBERGER SP42 belongs to a hard-turning series for the economical machining of complex components. Its design focuses on rigidity, stability and machining accuracy. These characteristics are important when processing hardened workpieces with tight tolerances and demanding surface requirements. A central feature of the SP series is the option to combine hard turning and grinding in one setup. This can simplify process chains and reduce setup operations. Fewer transfers between machines can also support more stable and repeatable production.
The machines use a vibration-optimised solid cast-iron bed, drive technology and machine kinematics. These features are intended to deliver reproducible results in the micron range. The SP42 main spindle reaches up to 6,000 rpm. The larger SP51 and SP65 models operate at up to 5,000 rpm. Together, the three models form a scalable platform for different hard-turning requirements. Applications include automotive, aerospace, bearing production and general mechanical engineering. At AMB, Kellenberger will show the SP42 as the compact model in this range.
Modular grinding configurations for varied workpieces
Kellenberger will also exhibit the KELLENBERGER K100 universal cylindrical grinding machine. The platform is intended for manufacturers processing a broad range of workpieces. These include individual components, small batches and series production. The K100 is available with centre heights of 200 or 250 mm. Distances between centres are available in 600, 1,000 or 1,700 mm versions. The X-axis travel is 365 mm. Z-axis travel is available in 760, 1,150 and 1,800 mm versions. These dimensions allow the machine to be configured for different component sizes. Its modular design includes ten grinding-head configurations. It also features a CNC-controlled direct-drive B-axis and options for internal and external grinding. This approach allows users to adapt the machine to different grinding tasks and limit setup time.
The latest generation of Kellenberger’s BLUE Solution operating and programming software is also part of the machine concept. Its gSHAPE programming tool supports the graphical, workpiece-oriented creation of grinding programs. This is intended to reduce programming effort when introducing new components. It is particularly relevant where changing workpiece requirements demand flexible machine configuration.
