Haas Schleifmaschinen has come up with something very special for the first international meeting of the metalworking industry in 2021. The specialist for turnkey solutions from Trossingen will be demonstrating high-tech grinding at its most precise at the EMO in Milan. 

Haas Schleifmaschinen has innovative complete machining solutions for cutting and forming tools, as well as the machining of extruder shafts and, of course, its software solutions. After all, it is the software that makes the universal grinding machines from the Multigrind® series true specialists, with which virtually all grinding challenges can be tackled economically.

Cutting tools: One solution for an infinite number of possibilities  

With the Multigrind® CU on display and the Multigrind® Horizon software, customers of Haas Schleifmaschinen 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® 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.

Forming tools: More economical production with maximum precision

Anything goes: contour production, square grinding, runout interpolation, alignment surface, tip radius and chamfer grinding - even complex forming tools can be machined in just one setup with the familiar Haas precision. And they have to be. Because forming tools are expensive, often made of PM high-performance steel or carbide, one-off pieces. Grinding is therefore already the first choice today, as customer requirements in terms of complexity, dimensional accuracy and reproducibility have risen and continue to rise. In addition, production must also be significantly more economical, and it is precisely here that software solutions play a decisive role. This is because Multigrind® Horizon offers maximum flexibility, endless possibilities and the achievement of absolute precision in the production of forming tools. For example, different punches can be processed chaotically in one job. The jobs can be read in programmed via a web store and processed entirely in the spirit of Industry 4.0. Thanks to individual combination and parameterization, exactly the forming tool that is needed at the moment - faster and more precisely than ever before - can be produced. And it is irrelevant how often a grinding process is repeated, the result always remains within the tolerance range. Even when general conditions change, e.g. due to temperature fluctuations. Because software, workpiece and machine are in constant dialog with each other, deviations in the abrasive are brought back into shape in good time. The "closed loop process" enables maximum precision in series production up to batch size 1.

Extruder shafts: Demanding in terms of geometry and material design

On the Multigrind® CB on show, Haas Schleifmaschinen uses the example of an extruder shaft to demonstrate 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 completely 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 expenditure of time 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.
