Hard Gear Finishing and Polish Grinding
August 1, 2014
Reishauer Corporation will feature gear grinding technology. The RZ260 features Reishauer's continuous generating gear grinding. It has been increased in size and all relevant components have been adapted to handle higher loads and forces that occur when grinding larger gears. Gears with an outside diameter of 260 mm and modules up to 5 mm can be ground.
An important focus in the design of the machine concept was adaptability to different production requirements. The machine can be fitted with one or two work spindles. The version with two work spindles is used to minimize the loading times. When investment and tooling costs must be minimized and/or the workpiece handling times are not critical, the RZ260 with a single work spindle might be a more suitable choice. When grinding gears with space limitations or small lot sizes, it might be advantageous to use the changeable Profile Grinding Spindle, enabling the use of a small plated or dressable wheel to grind gears using the discontinuous profile method. Both versions of the RZ260 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 normally workpiece specific.
Also on display will be polish grinding on a Beveloid gear used in a marine transmission. The grinding wheel has two different sectors and compositions. One area is used to grind and remove the heat treat distortion, and the other area is used to polish the tooth surface. This process achieves a surface finish of .07 micron. The polish ground process also rounds out the edges at the transition of the workpiece flank and face. The topography of the flanks remains unchanged.
Design characteristics include the Reishauer Generating Module for gear quality, Reishauer LNS Low Noise Shifting technology for low gear noise emissions, Polish Grinding for surface roughness reduction, Reishauer Twist Control Grinding technology to create defined values for flank twist and the Reishauer HMI for fast change over and set-up times.
