At AMB 2026, Knoll demonstrates how automation can extend beyond the machine tool itself. Its solutions range from customized coolant filtration and automated KSS analysis and dosing to driverless systems for chip transport and material handling.

Knoll is a specialist in filtration and conveying for the metalworking industry and a versatile automation partner for processes surrounding the machine tool. At AMB, the company will showcase three examples of its portfolio: customized filtration technology represented by the Hydropur, the new fully automatic Controlube system for coolant analysis and dosing, and a Knoll FTS, which can be used not only for automated chip transport.

Any metalworking company that wants to succeed in this country must automate. This can be seen this year at the largest national trade fair, AMB, at almost every stand in every hall. Automation is also the number one topic at Knoll Maschinenbau. At the trade fair stand in Hall 8, 8C40, the Bad Saulgau-based company demonstrates how coolant lubricant (KSS) and chip management can be brought up to the latest state of the art.

Nothing works without clean coolant lubricant

At the center of the trade fair stand is a hydrostatic filter Hydropur 250, representing the diverse Knoll KSS filter portfolio that supplies cutting machine tools with cleaned coolant (emulsion or oil) according to requirements. The Hydropur filter is available in the 250 / 400 / 700 / 1000 variants, corresponding to the different maximum filtration capacities. The different filter sizes come with options regarding tank size, vacuum support, continuous fabric (instead of filter fleece), magnetic roller, and winding unit. Thanks to its modular design based on standard components, a customer-specific filter can be configured that delivers outstanding filtration performance and filtration fineness, while also offering an attractive price-to-performance ratio.

Process reliability through consistent coolant quality

At the Knoll trade fair stand, the Hydropur also serves as a practical example of the use of Controlube, the newly developed system for the automatic analysis and dosing of coolants. Controlube consists of a central mixing and control unit as well as decentralized analysis units at the respective filter systems. They continuously take samples from the filter’s clean tank and analyse relevant coolant/lubricant parameters on site, such as concentration, temperature, pH value, and conductivity. The measurement data are transmitted to the central mixing and control unit. If there are deviations from the preset target values, it automatically prepares the required emulsion from water and concentrate and doses it as needed.

This keeps the coolant quality consistently stable — an important contribution to process reliability, tool life, and machining quality. At the same time, the manual effort required for monitoring and documentation is almost completely eliminated.

Driverless transport systems automate material flow / chip transport

In addition to media supply, Knoll is also focusing on the material flow around the machine tool at AMB. The company demonstrates live how chip transport can be automated using a driverless transport system (FTS). For this purpose, a chip conveyor is set up that continuously transports chips into a collection container. As soon as a defined fill level is reached, a transport order is automatically generated. The FTS brings an empty container to the machine, swaps it with the full container using the so-called double-pick method, and transports it for emptying. The changeover time is around one minute, during which the machine tool can continue operating.

Knoll provides all components and the entire process from a single source. How well thought out the system is, is demonstrated by one detail: to prevent any coolant or oil from dripping from the conveyor onto the floor during the chip container change, Knoll developed a mechanical drip protection.

Another advantage is the independence of the FTS-supported chip disposal system developed by Knoll. The system can be connected to machine tools from various manufacturers, enabling seamless automation across the entire machine fleet.

Another advantage: the FTS used for chip disposal can also transport raw parts, workpieces, pallets, or material carriers and link different machining stations together. Knoll already implements applications today in which components are transported autonomously between machine tools, robot cells, transfer stations, and downstream process steps.
