Cutting methods for thread production
The comprehensive complete range of tools for machining various materials and diameters includes a wide variety of taps with the highest levels of precision, quality, cost-effectiveness and process reliability in addition to turning and milling tools for thread production and compatible toolholders and indexable inserts. For tapping, especially sophisticated threading tools made from high-performance solid carbide and high-speed steel (HSS-E, HSS-PM) cutting tool materials are available from Walter. High-quality coatings tailored to the material to be machined help to achieve production goals such as dimensional stability, short machining times, long tool life and outstanding results when producing threads. In addition, the form and geometry of our taps ensure low wear and greater efficiency – for example through improved chip removal using optimised flutes and rake angles.
As a result, our solid carbide taps also meet the high requirements for production of all thread types, e.g. in the automotive industry. When it comes to thread turning, Walter impresses with threading tools which feature one or more cutting edges and have been developed for precise production of all common internal threads. In the case of turning and milling tools for thread production, highly robust tool holders and ISO boring bars, ISO square shanks and threading inserts with cutting edges of different lengths (11, 16 and 22 mm) and compatible indexable inserts complete the range. Full profile and partial profile versions of our three-edged indexable inserts, for example, are ideal for all common external and internal threads. These different indexable insert versions make it possible to produce complete and absolutely precise threads with the highest surface finish quality and dimensional accuracy. Besides thread mills made from different cutting tool materials (solid carbide), the wide selection of Walter thread milling cutters also includes indexable insert milling tools. These indexable insert milling tools make it possible to produce external and internal thread diameters in all common sizes and materials on CNC machining centres. From steel and stainless steel to cast iron, non-ferrous metals, such as aluminium, right through to titanium, tungsten and molybdenum alloys and hardened steel – regardless of the thread profile and thread pitch. With us, you can always find the right tools for virtually all applications, depths of cut and workpieces. Orbital thread milling, for example, also makes it possible to produce very deep and also very small internal threads. Completely reliable, even in demanding materials.
