The RZ 60 gear grinder’s productivity sets the standard for high volume production of planetary pinions and remains the fastest machine on the market.
The RZ 60’s overriding design principle is the resolute reduction of unproductive times. This is based on its dual spindle technology, all axes movements and routines being uncompromisingly executed in parallel, the short reaction times of all spindles, and the high cutting speeds.
The extremely rigid overall design leads to very high material removal rates and constant workpiece quality.
All overtravel movements of the RZ 60 have been reduced and optimised to the absolute minimum. The electronic gearbox, which was fully developed by Reishauer, controls the perfect harmonisation of multiple NC axes and executes all routines in parallel such that idle times are almost completely eliminated.
Two meshing sensors synchronise the gear parts to the threaded wheel during the rotation of the workspindle turret. Furthermore, sufficient time remains during the rotation of the turret to centrifuge off oil from the ground parts, even at cycle times shorter than 10 seconds. Additionally, the threaded wheels’ chosen extra width and the multi-rip full profile rolls reduce non-productive dressing times to a minimum.
Short set-up times highlight the flexibility of the machine. Apart from disk-type workpieces, this machine equally handles shaft-type workpieces. Due to its compact design, and the fact that it comes fully equipped, it can be easily integrated into existing production lines.
Last but not least: hundreds of RZ 60 machines that unflaggingly generate income for our customers are the best proof of the performance level of this machine.

Working Range Given values that may differ can be verified upon request.The Reishauer Tool Division develops, produces and markets highly specialized diamond and CBN tools in electroplated bond for dressing, grinding, in addition to other special applications. High quality, in terms of precision tool life and wear resistance, is based on many years of experience and a great willingness to innovate.
Reishauer strives for the best technical and cost effective solution in each Application. This also applies to our dressing discs and dressing rolls. The different tasks required for the manufacture of small, medium or large lot size, as well as specific demand regarding geometry and flexibility, determine the tool profile for each application. In combination with the corresponding dressing process, virtually all demands are met in the dressing of grinding wheels for the continuous generating grinding of involute and non-involute gear teeth. Reishauer’s engineering competence and manufacturing know how guarantee optimum process reliability.
In line with its performance portfolio – the Circle of Competence – Reishauer not only builds its gear grinding machines but also manufactures its proper grinding wheels, called threaded wheels, in its own factory in Central Switzerland.
Within the gear grinding process, the grinding machine supplies the kinematics, i.e. the precise movements that control the threaded wheel. For its part, the threaded wheel must transfer these movements onto the workpiece by grinding it accurately to a defined size and a predetermined surface quality.
A threaded wheel consists of three elements, all of which have to fulfil a specific purpose. These elements are: the abrasive grits, the bond and the pores. In short, the abrasive grits’ task is to perform the cutting of hardened steel to size and to a specified surface finish, all without generating any grinding burns. The bond, the second element, holds the grits in place and must ensure the safety of the grinding process at high operating speeds. The pores, as the third element, give the grinding wheel an open structure to ensure that the coolant gets into the contact area during grinding, and that the chips generated during the process can be transported away from the grinding zone.
Reishauer threaded wheels have designed specifically for the process of continuous generating grinding. Each and every threaded wheel is subjected to a rigorous quality checking procedure and marked with an indelible laser induced “birthmark” that ensures permanent product traceability.
Reishauer builds on its own comprehensive knowledge of the gear grinding process and on this basis, develops and manufactures customer specific clamping devices. The connection « machine – clamping device – grinding wheel – dresser » - makes possible a grinding process that is optimally fine-tuned to specific quality.
The specific use of base chucks for workpiece specific hydraulic arbours reduces the set-up time and increases productivity. This translates into the full use of the high economic potential of the Reishauer machine, whether for large or small scale production volumes.
Reishauer’s own automation concept is an integral part of its performance portfolio. This part loading automation keeps pace with the machines fast cycle times, productivity and availability. Automation and machine are in perfect synch as they share their place of origin, the same CNC control philosophy and the same interfaces. Material flows can be easily synchronised and optimised to the specific operational requirements.
This loader system offers customers completely new degrees of freedom. It can equally handle disk-type or shaft-type workpieces, from small planetary gears to heavy-duty final drive gears. The loader’s high flexibility ensures that the user can quickly respond to future production requirements. This automation can be configured independently of the part supply system (e.g. plate chain conveyor, single tray or stacked trays). The modular design enables the integration of additional functions such as gear flank analysing, deburring with rotary brushes, oil centrifuging, laser marking, over ball measurements, SPC, etc.
The Reishauer wheel mounting cart, ErgoMount, enables the machine operator to ergonomically and safely change grinding wheels and clamping tool arbours up to a weight of 40 kg. The unit has been designed for the RZx60 gear grinding machine series. It allows the direct mounting of a grinding wheel on the main spindle without any additional tools. Thanks to the well-thought-out fast-changeover system and the relevant load-bearing elements, the changeover between the setups for grinding wheels and clamping arbours is done in next to no time. The electrical lifting axis is controlled by a joystick and makes for comfortable operation.
