    • Continuous generating grinding
      For continuous generating grinding all tooth flanks of the workpiece are machined simultaneously during one stroke of the helical tool. This is realized with a synchronized constant rotation of the workpiece relative to the grinding tool. Due to the kinematics of this process indexing and positioning times are greatly reduced resulting in low cycle times. Therefore it is a highly productive and cost-effective process well suited for small and medium-sized gears. Both dressable ceramic tools and non-dressable CBN tools can be used (in cylindrical or globoid design).

      Discontinous profile grinding
      Profile grinding of gears describes a process for which the tooth flanks are machined gap after gap with single or multi-ribbed profiled tools. Regarding the possible work piece geometries this process offers highest flexibility while achieving highest quality. Profile grinding is mostly utilized for small batch series and prototype manufacturing. Dressable ceramic wheels as well as non-dressable CBN-tools can be used for this grinding process.

            Due to the innovative drive concept on the tool side, a maximum drive power of 46 kW is reached. Especially for roughing, this high performance results in extremely high stock removal rates and shortens machining times considerably. In combination with an optimally adapted tool technology, a highly productive and efficient working process will be guaranteed.

            With regard to pre-grinding, the patented rotor grinding machine RX 120 provides the option to use the advantages of continuous generating grinding instead of profile grinding in manufacturing rotor profiles. For the finishing operation, only profile grinding is used. By applying the generating grinding process as the pre-grinding process, a reduction of up to 40 % in grinding times can be realised compared to conventional machines and processes.

              Machine concept

              The profile grinding machines of the VX series are extremely suitable for meeting the highest requirements concerning the final quality of the produced gears. Both dressable tools and non-dressable CBN tools may be used in the process. As the grinding adapter can be fitted with two exchangeable grinding spindles, the cutting passes can be realised with the sequential use of roughing and finishing tools in one workpiece set-up. As an alternative, multiple gears can be machined in one set-up.

              VX machines configured for the use of dressable tools feature integrated dressing equipment producing any type of grinding wheel profile. The dressing and grinding programme is generated automatically based on the gear data. The combination of measuring system and profile dressing equipment also allows for automated machining according to the so-called GMG-strategy (grinding - measuring - grinding).

              machine concept

              The machines of the RX series are used for pre-finish and finish grinding of pre-profiled steel and cast iron screw rotors.

              Due to the innovative drive concept on the tool side, a maximum drive power of 46 kW is reached. Especially for roughing, this high performance results in extremely high stock removal rates and shortens machining times considerably. In combination with an optimally adapted tool technology, a highly productive and efficient working process will be guaranteed.

              With regard to pre-grinding, the patented rotor grinding machine RX 120 provides the option to use the advantages of continuous generating grinding instead of profile grinding in manufacturing rotor profiles. For the finishing operation, only profile grinding is used. By applying the generating grinding process as the pre-grinding process, a reduction of up to 40 % in grinding times can be realised compared to conventional machines and processes.

              • GAS / GIS / HGS

              • GAS

                Machines from the GAS series are used for processing external threads and similar profiles. Typical components for these machines are external ball screws for automotive steering systems, as well as drive worms and small pumps and metering components. Parts are only machined by discontinuous profile grinding with non-dressable CBN profile grinding wheels or dressable ceramic grinding wheels.

                GIS

                Machines of this type are used for the hard and soft finishing of internal threads in ball screw tracks or similar profiles. Typical applications besides vehicle steering are recirculating ball screws in the field of automotive.

                Parts are machined by discontinuous profile grinding.

                Non-dressable CBN profile grinding wheels are exclusively used, typically in a combination of roughing and finishing tools.

                HGS

                The high-speed grinding machine HGS is mainly used for grinding slots in pump rotors into the solid, through-hardened material. Slot widths of 0.5 to 2.0 mm can be produced with high efficiency due to package clamping and automatic unloading and loading. The in process measuring control ensures maintaining slot width tolerances.

                The HGS uses non-dressable CBN profile grinding wheels only.
