The RZ 303C precision gear grinding machine incorporates innovative technology including gearless planetary drives, acoustic sensing for alignment of dressing diamonds, and LNS low noise shifting.


The RZ 303C precision gear grinding machine incorporates gearless planetary drives; acoustic sensing for alignment of dressing diamonds; and LNS low noise shifting – a feature that produces a random surface structure on the teeth to prevent excitation.

The machine working area was designed to facilitate fast changeovers. Convenient location for the setup of the dressing unit, ergonomic ease of wheel change and almost unlimited restriction of the gear location on the shaft or arbor allows the RZ 303C to provide maximum machine uptime. The main column that carries the grinding spindle and slide rotates 180° in total; from its grinding position, it rotates 90° to facilitate wheel change and another 90° to perform the wheel dressing operation.

Specific gear tooth geometry can easily be realized using part specific galvanic plated composite diamond rolls manufactured by Reishauer for the RZ 303C. Using the machine axis, the wheel is moved in such a manner during the dressing cycle to produce root, flanks and tip modifications in a minimum number of passes that will be imparted to the gear when grinding.

The primary on-board loading system is designed for transporting un-ground parts into a high production gear grinder. The parts can be organized in stacks of steel or plastic baskets and served by an in-plant conveyor style, table or basket buffering handling systems.

The compact cell creates a highly flexible and efficient manufacturing environment by de-coupling individual processes. Each machine and cell has an optimum buffer of parts that provides significant machine autonomy with minimal operator attendance. The cell is compact in size and facilitates system designs that are inherently scalable and easily optimized.
