Gear Grinding Machine Offers Flexibility

Reishauer's RZ260 gear grinding machine enables continuous generating gear grinding. Based on the company’s RZ160 series machine, the grinder’s increased size and adapted components accommodate larger loads and forces to reliably grind gears with outside diameters ranging to 260 mm and modules ranging to 5 mm.

Reishauer's RZ260 gear grinding machine enables continuous generating gear grinding. Based on the company’s RZ160 series machine, the grinder’s increased size and adapted components accommodate larger loads and forces to reliably grind gears with outside diameters ranging to 260 mm and modules ranging to 5 mm.

The RZ260 was developed to accommodate the different production requirements of its users. The machine can be fitted with one or two spindles, with the two-spindle version said to minimize loading times. For small lot sizes and limited spaces, a changeable-profile grinding spindle enables the use of a small plated or dressable wheel to grind gears using the discontinuous profile method. Both configurations can be equipped with a fixed or CNC axis, which provides flexibility and enables the use of the same tool on a range of gears.

The grinding wheel has two different sectors and compositions; one grinds and removes heat treatment distortion and the other polishes the gear tooth surface. According to the company, this process achieves a surface finish of 0.07 micron and rounds out flank/face transition edges while keeping flank topography unchanged.

In addition to its updated features, the RZ260 grinding machine incorporates the company’s generating module for high gear quality, low noise shifting system for low gear noise emissions, twist control to create defined flank twist values and an HMI for fast change-over and setup times.
