RX series

Product catalog summary

Overview: The RX series machines are designed for both pre-finish and finish grinding of pre-profiled steel and cast iron screw rotors. These machines feature an innovative drive concept that achieves a maximum drive power of 46 kW, significantly enhancing roughing performance by increasing stock removal rates and reducing machining times.

Grinding Process: The RX 120 rotor grinding machine offers a patented approach that utilizes continuous generating grinding for pre-grinding rotor profiles, as opposed to traditional profile grinding. This method can reduce grinding times by up to 40% compared to conventional machines. For finishing, profile grinding is exclusively used.

Machine Specifications:

RX 120: Maximum outer diameter of 120 mm, workpiece length of 425 mm, profile length of 220 mm, profile width of 80 mm, and profile depth of 30 mm.
RX 55: Maximum outer diameter of 320 mm, workpiece length of 1,200 mm, profile length of 550 mm, profile width of 180 mm, and profile depth of 80 mm.
RX 59: Maximum outer diameter of 320 mm (400 mm), workpiece length of 1,650 mm, profile length of 850 mm, profile width of 180 mm, and profile depth of 80 mm.

Automation and Efficiency: The RX 120 is equipped with a compact automation concept that includes an integrated deburring station, enhancing the efficiency and productivity of the grinding process.

RX 120 with compact automation concept with integrated deburring station RX series Rotor grinding machine G KAPP NILES 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. workpiece length profile length [mm] [mm]
