Info v c Product Finder 2.4 Special roll form tap types (examples) Special taps to customers’ specifications EMUGE produces special roll form taps to customers’ drawings and proper specifications. InnoForm special tools If our comprehensive InnoForm program of roll form taps does not include a suitable tool design for a specific application, we will be happy to furnish a custom-made, special InnoForm tool designed for the work conditions and according to the workpiece drawing of the individual customer. Such special designs can be made in special thread sizes and tolerances, with special thread profiles and dimensional specifications, or for special processes involving combined thread cutting and cold forming. Special threads (examples) 60° 60° A B Bicycle thread acc. DIN 79012 Tripod connection thread acc. DIN 4503 60° 60° Sheet metal screw thread acc. DIN EN ISO 1478 ISO Metric thread for tight fit acc.

DIN 7756 MFS FG ST Vg A/B 2.5 Basic types of our EMUGE roll form taps EMUGE is the first threading tool manufacturer worldwide to introduce a program of roll form taps specially designed for the machining of specific materials or material groups. While this was possible only for cutting tools, we have succeeded in designing roll form taps especially for the special properties of single materials and material groups, sometimes increasing performance in a dramatic way. Until then conventional roll form taps were made for the use in all ductile materials: potential performance features in defined applications were simply wasted in the process. EMUGE has made extensive investigations into the mechanisms of cold forming for years, and developed an entirely new tool generation from the results. In order to highlight the uniqueness of this highly innovative program of roll form taps, we have thought of a new name: InnoForm Druck STEEL GAL Z SPEED InnoForm STEEL-M STEEL-H VA AL GAL H Z • Roll form tap for the chipless production of internal threads • Lead taper form E (1.5-2 threads) • Lead taper form C (2-3 threads) • Lead taper form D (4-5 threads) • For blind hole and through hole threads Note: Depending on the workpiece material, the essential advantages of the cold-forming of threads are not only excellent surface quality but also higher static and dynamic strength of the thread. The length of the thread to be produced is not limited by chips which must be removed. The tools feature an excellent stability, especially with small thread sizes. All ductile materials can be cold-formed. Sufficient lubrication is essential. We generally recommend using oil grooves for through hole threads and horizontal machining. (Exception: very short through hole threads, e.g. sheet metal components). Sometimes, it is necessary to adjust the recommended thread hole preparatory diameter to work conditions.
