Welcome to Reishauer
Gear Grinding Technology

Why is Reishauer unique?

BECAUSE WE SET THE STANDARD OF TECHNOLOGY, EVER SINCE INVENTING CONTINUOUS GENERATING GEAR GRINDING

1788

Foundation of the company in Zurich, Switzerland.

1945

Reishauer launches the first continuous generating gear grinding machine in the world. We predicted in the accompanying brochure: “In the future, gears will be ground which we cannot grind today due to high costs, even though it would be preferable to do so now.”

Today,

our prediction has long since been turned into reality, and our goal continues to be: To provide our customers with innovative solutions so they can create added value; at the highest levels of part precision and process reliability.

Because we continue to set the standards

2022
GDE-based Closed Loop: Direct, clear comparison of target and measured data: The GDE format (Gear Data Exchange Format according to VDI / VDE 2610) is used as the interface between grinding and measuring systems.
2023
Reishauer launches its application platform myReishauer. myReishauer provides an overview of detailed grinding process data down to each individual workpiece.

Reishauer makes it possible to manufacture efficient, quiet-running and durable transmissions. As the leading provider of gear grinding technology for many decades, Reishauer continues to set the industry standards.

Reishauer's history

BECAUSE WE FOCUS ON IN-HOUSE MANUFACTURING

BECAUSE WE TAKE CONTROL OF OUR SUCCESS FACTORS

REISHAUER CIRCLE OF COMPETENCE: 
OUR PERFORMANCE PORTFOLIO – ALL FROM A SINGLE SOURCE

BECAUSE OUR MACHINES STAND FOR CONSISTENT HIGH-PERFORMANCE

Worldwide, the majority of hard-finished gears are precision-ground on Reishauer machines. Our machines are the result of focused, decade-spanning development, and of an uncompromising quality strategy – today and in the future.

BECAUSE OUR MACHINES STAND FOR CONSISTENT HIGH-PERFORMANCE

TWIN-SPINDLE TECHNOLOGY

The twin-spindle concept markedly shortens cycle time and ensures the high production output of the Reishauer continuous generating grinding machines. While one part is being ground, the previously ground part is unloaded and a new part is loaded and meshed simultaneously into grinding position.

REISHAUER’s ELECTRONIC GEARBOX

The in-house developed electronic gearbox coordinates the complex axes movements of the continuous generating grinding process and creates the exact geometry of the gear.

REVOLUTIONARY PROCESSES

For decades, continued focused development of the grinding process has given Reishauer the technological lead in the hard-finishing of gears. To name but a few examples: high-speed grinding with 100 meters per second (m/s), polish grinding and topological grinding.

BECAUSE WE HAVE A FIRM GRIP ON GEARS

The Reishauer machine sets a fast production pace, with the part loading automation in perfect phase. Whether shafts or disk-type parts, the Reishauer automation is the ideal extension of the machine.

SEAMLESS INTEGRATION

The automation concept is an integral part of the Reishauer performance portfolio, and as such, ensures the perfect communication between grinding machine and part loading.

CUSTOMER SPECIFIC SOLUTIONS

The modular design accommodates a broad spectrum of customer specific solutions. For example, these include pre- and post-processing measuring of the gears, offload of parts to SPC drawer, spinning off excess oil, deburring and laser marking.

SIMPLE INTEGRATION INTO THE PRODUCTION PROCESS

Whatever the part carriers; conveyor belts, stacking cells, baskets or pallets, Reishauer automation supports any type of part supply system. It can be simply integrated into existing transfer lines. Additionally, it also offers comprehensive solutions for the layout definition of new material flows.

BECAUSE WE HAVE A FIRM GRIP ON GEARS

BECAUSE WE MANUFACTURE TOOLS PERFECTLY ADAPTED TO THE PROCESS

As the solution supplier for the continuous generating process, we know: The best machines need the best tools.

GRINDING WHEELS

Our grinding wheels hold form and maintain their free-cutting ability even when subjected to heavy cutting loads. Our in-house production guarantees consistency from batch to batch, and by extension, an optimal process stability to the customers.

DIAMOND DRESSING TOOLS

Highly accurate parts require highly precise diamond dressing tools. Because we have developed the continuous generating grinding process, we can design appropriate dressing tools and optimise them for a long service life.

WORKHOLDING

Our fixtures are distinguished by their outstanding concentricity, long service life and reliable functionality. Fine-tuned to specific customer parts, they are an important part of our performance portfolio.
