Reishauer’s RZ 260 has not only been increased in size, all relevant components have been adapted to handle higher loads and forces, which occur when grinding larger gears. Gears with an outside diameter of 260 mm and modules up to 4 mm can be ground.
An important focus in the design of the machine concept is its adaptability to different production requirements depending customers’ individual requirements. The RZ 260 can be fitted with one or two work spindles. The version with two work spindles greatly minimizes the loading times while increasing overall production output. Both the single and dual spindle versions of the RZ 260 can be equipped with a fixed or CNC-controlled axis for swiveling the dressing tool. With this option, the flexibility of the dressing tools can be increased since the same tool can be used for a range of gears as compared to the fixed dresser where the tools are usually work piece specific.
The RZ 260 also features a changeable Profile Grinding Spindle, which is ideal for grinding gears with space limitations or small lot sizes. This enables the use of a small plated or dressable wheel to grind gears with the discontinuous profile method.
The RZ 260 incorporates advanced machine technology including the Reishauer Generating Module for gear quality, Reishauer LNS Low Noise Shifting technology for very low gear noise emissions, Reishauer Twist Control Grinding technology to create defined values for flank twist and the Reishauer HMI for fast change over and set-up times.
