It is available ex stock in numerous thread systems and sizes. Circumference speeds can be increased by combining it with a suitable hard surface coating. • InnoForm STEEL-M – For medium strength steels • InnoForm STEEL-H – For high strength steels InnoForm For stainless steel materials and steel materials These materials show a high degree of adhesion which can lead to cold-welding effects. Also, they tend to strengthening during the forming process which puts more stress on the forming lobes. In order to compensate this, we have developed a geometry which meets the elevated requirements towards stability perfectly. InnoForm For aluminum wrought alloys Under the usual lubrication conditions, e.g. emulsion lubrication, these materials show a strong inclination to adhesion in the cold forming of threads. In order to obtain satisfactory work results in spite of these unfavourable material properties, this geometry was provided with a coating that offers excellent friction characteristics and, as a result, a perfect degree of process safety. Druck InnoForm For aluminum cast alloys Cast aluminum materials exert a very strong abrasive stress on the forming lobes of a roll form tap during work. In addition, the ductile properties of these rather brittle materials must be regarded as relatively poor. In order to achieve easier thread production and better wear resistance even under these bad conditions, we have given this tool type a specially adjusted geometry and an additional hard surface coating. InnoForm For materials of high tensile strength This geometry was designed for the cold forming of materials with restricted ductile properties. The special tool geometry, combined with an appropriate hard surface coating, provides excellent quality of the finished threads and very good wear resistance. Druck InnoForm For CNC-controlled machines This geometry is aimed at reducing the unavoidable friction forces and the heat stress on the forming lobes especially for use on CNC-controlled machines. With a synchronous feed control, the performance potential of these tools can be used to the full, especially in combination with the collet holders of our Softsynchro ® series. Druck InnoForm For high-speed tapping CNC machines, especially in combination with the collet holders of our Speedsynchro ® Modular series, make very high speeds possible. The special geometry of these tools, combined with a hard surface coating, offers you the chance to do your machining at the highest speeds your machine can manage. 2.7 Our EMUGE surface treatments and coatings NT TIN Nitriding In a thermo-chemical treatment, the surface is enriched with nitrogen to a depth of approx. 0.03 to 0.05 mm. Since the surface becomes very hard (1000-1250 HV), nitrided tools are a very good choice for abrasive materials like cast iron, spheroidal cast iron, cast aluminum and duroplastics. Tool life is increased in a decisive manner. Titanium nitride (gold-yellow) In a PVD process (500 °C) a coating thickness of 3-7 μm can be realized. The smooth coatings feature a high adhesion strength and TIN-typical properties against cold welding. TIN coating systems with additional code number (e.g. TIN-66, TIN-80) are optimized with regard to substrate, tool geometry and application. TICN GLT-8 Titanium carbonitride (blue-grey) In a PVD process (500 °C) a coating thickness of 2-4 µm can be realized. The hardness is approx. 3000 HV. The TICN coating will resist up to approx. 400 °C. TICN coating systems with additional code number (e.g. TICN-67) are optimized with regard to substrate and application. Diamond-like, amorphous carbon coating (black-grey) In a PVD process a coating thickness of 1-2 µm can be realized. The hardness is approx. 2500 HV. This mono-layer coating is an excellent choice for the machining of non-ferrous metals and aluminum with a low silicon content (< 7% Si). Thanks to the low friction, material adhesion is drastically reduced. This coating will remain resistant up to approx. 350 °C.
