Product Portfolio

  • Single Systems

  • KNOLL single systems are accessories for machine tools or components of central systems. They serve to separate, transport and prepare chips and cooling lubricants. Many well-known machine-tool manufacturers and users in the field of metalworking put their money on KNOLL products when it comes to wet and dry machining. Whether it be chip conveyors, filters, or extraction or pump-back stations: KNOLL devotes all its efforts to customer requirements. From standard products individually tailored plants are created: Machine-integrated, positioned on the side or centrally positioned.

      • Transport systems

      • KNOLL transport systems are ideally suited for use in logistics and assembly, even for heavy and very large parts. Because our systems are modularly structured mechanically, electrically, and in terms of their software, our specialists can implement custom-tailored solutions for you. Such systems guarantee a short amortization time and can be expanded nearly at will. The input-side visualization of the controller makes for easy operation.

                      • Central systems

                      • If chips and/or cooling lubricants are transported completely automatically to a central point and should be treated there, system solutions are required. These are individual systems and components that are linked to form one system. KNOLL can offer you all required services, from planning to production to start-up, all from a single source. Then our customer service ensures safe and economical operation. And if the system should be expanded or reconfigured, KNOLL is the right partner for you.

                          • Systems with pump technology

                          • A conveyor and filter system with pump technology is suitable for fully-automatic chip transport from several processing machines to a central filter system. Cooling lubricant serves as the carrier medium. This system is especially advantageous in production areas with a large machine park. It is constructed to save space and be flexible with regard to its overall height. The user has many possibilities for expanding and converting his machine park. Little maintenance and service is required.

                            Properties:

                            • High flexibility in the erection or changeover of the machine train
                            • Low space requirement due to above-floor pipelines
                            • No plant components within the hall floors
                            • Low maintenance and upkeep

                              • Systems with extraction technology

                              • A conveyor system with extraction technology is suitable for fully-automatic chip transport from several processing machines to a central collection point. Room air serves as the carrier medium. It can transport dry or slightly damp chips across a distance of up to 560 m. With the use of modern fans and control technology, the system requires little energy. It is also space-saving and offers great flexibility for the setup or conversion of the machine park.

                                Properties
                                • High flexibility in the erection or changeover of the machine train
                                • Low energy requirement thanks to the use of modern blowers and control technology
                                • Easy routing and low space requirement of above-floor pipelines
                                • Safe, fast and clean transportation with long service life
                                • Low maintenance and upkeep
                                • Material mix (e.g. aluminium, steel or cast iron) possible with one system

                                  • Systems with collecting conveyors

                                  • Collecting conveyor systems are required to bring metal chips and small parts from production to a central collection point. Initially, integrated systems convey the chips from the machine tool. They transfer their freight to collecting conveyors. If the distances are large, transfer stations and appropriate control technology is required. Depending on spatial and production-technical circumstances, individually customizable underfloor, overfloor or on-the-floor solutions are available.

                                    Properties
                                    • High flexibility in the erection or changeover of the machine train
                                    • Simple technology
                                    • Low planning

                                      • Systems for chip processing

                                      • The treatment of chips has many advantages: they are dry and separated by type, so disposal costs are low. Depending on the material, it may even be possible to sell the chips. A system for chip treatment includes different components depending on the requirements: conveyor and collection devices, magnetic separator technology, filter and volume-reducing briquetting presses. And containers or chip silos are also required. The components can be linked to one another and operated completely automatically.

                                        Properties:

                                        • Chip drying is essential to ensuring safe transportation on public routes
                                        • Volume reduction reduces storage and transportation cost
                                        • Recovery of chips and cooling lubricant protects the environment and reduces
