Over the past few years, Haas Schleifmaschinen has installed a wide variety of turnkey solutions that produce cutting tools for a wide range of manufacturing processes. Around the globe, the high-tech grinders from Trossingen have earned an excellent reputation among precision tool manufacturers. The reputation is based on the precision and cost-effectiveness that result from the perfect interaction of hardware and software.

At the GrindTec, the high-tech grinding machine manufacturer had a whole range of turnkey solutions in its luggage that are absolutely fit for the future. The new operating concept of the Multigrind® Radical, which has been fundamentally rethought, stood out in particular. The focus here is on the consistent decoupling of operation and machine. This logical reduction brings unprecedented independence. With the new operating concept, the machine becomes a pure executor.

Machine control made easy.

Because everything in grinding revolves around the NC code, operation or programming in CNC grinding has always been inextricably linked to the machine itself. The high-tech grinding machine as a pure execution system was previously inconceivable. However, if calculation and machine are separated, completely new possibilities arise. The decoupling shifts the necessary computing load from the machine to the network.  This not only makes the generation of NC code more flexible overall, but also significantly faster. This is because scaling is possible in the network, but not on the machine.

This means that the operating concept offers a large degree of freedom even after many years of use. This is because the obsolescence of the machine's PC control system is prevented. Considerations about retrofitting and upgrading slowly aging control systems are therefore obsolete. In this way, the user can benefit directly from the permanent further developments in the software. This is because the NC code is calculated in the company network and not on the machine. The calculation is located in the company's own network and is thus available for execution via tablet, laptop and cell phone. This makes the work in front of the machine more flexible. In the future, the tool grinder will work on the move and will always be up to date wherever he is. By being located in the company network, operation is no longer limited to just one machine. This can be implemented for several machines via a freely selectable platform (tablet, PC, laptop). And the topic of IT security is also taken into account by the separation.

In addition to extending the service life of the machine, the operating concept offers scope for sustainable flexibilization of the working reality. Dispensing with the classic control system on the machine changes the workplace. A previously inflexible working environment is made more flexible. In addition, the location in the company network offers a better overview. Synergies also arise due to the common basis with regard to networking, documentation, interfaces, parts spectrum, production infrastructure, etc. 

Hardware and software: from a single source. Simply unbeatable.

The fact that the high-performance turnkey solutions are based on the perfect interaction of hardware and software as well as the permanent striving for innovation was also impressively demonstrated by the best practice of the production of skiving tools at the Multigrind® CU at the trade show booth in Hall 7. Unlike other solutions already established on the market, the Multigrind® Horizon grinding software calculates back from the perfect geometry of the cylindrical gearing to the geometry of the skiving tool. In this process, the motion sequences in production and the relative speed of the flanks define the future geometry of the respective skiving tool. Multigrind® Horizon thus calculates the exact path resulting from the movement of the gear.

In addition to software solutions and the production of skiving tools, Haas Schleifmaschinen had innovative complete machining solutions for cutting tools and the machining of extruder shafts in its luggage.

Cutting tools: One solution for an infinite number of possibilities

With the Multigrind® CU and Multigrind® CA universal grinding machines on display and the Multigrind® Horizon software, Haas Schleifmaschinen customers are able to easily define, simulate and apply a wide variety of contour and clearance angle constellations, for example on grooving plates. The constantly changing geometry of the diamond grinding wheels in such manufacturing solutions is no longer an obstacle, because the 5-axis Multigrind® universal grinding machine can be moved so precisely with the help of the control software that continuous peak values in dimensional accuracy are realized. Any inaccuracy due to grinding wheel wear is fully compensated for by the software. In this way, valuable time can be saved through significantly less dressing.

Extruder shafts: Demanding in terms of geometry and material design

On the Multigrind® CB on display, Haas Schleifmaschinen used the example of an extruder shaft to show that modern grinding processes often pay off several times over. Not only in terms of machining times, but also in terms of tool costs. These are comparatively low for grinding operations. However, the fact that complex workpieces can be produced entirely on one machine predestines the Multigrind® machine as a real alternative. This is because such workpieces are often produced on several different machines, which is associated with a higher time expenditure in terms of set-up and the actual machining. The reason for such complex production layouts can be seen in the demanding material designs, the different materials and the alloys. The fact that Haas Schleifmaschinen is the specialist for such turnkey solutions is demonstrated by its many years of expertise in the machining of Inconel, sapphire glass as well as carbide and special alloys.
