![]() Unlike thread cutting, no material is removed during thread forming. For ductile work materials, thread forming can provide better size control and stronger threads while improving tool life and productivity. The vast majority of threaded holes–more than 90%, according to one supplier of taps and other cutting tools–are produced using cutting taps.īut many of those threads could be produced using forming taps, which can provide multiple advantages. CrN - great choice for processing the materials of ISO N group and low alloy steel.In the right application, thread forming can boost quality and throughput.TiN - universal coverage with low frictional coefficient.It combines low friction with high hardness. TiCN - applied to one-piece carbide tap-burnishers.Three different coverings are available:.One-piece carbide taps for long tool life and maximum performance.Taps of powder high-speed steel for durability, wear resistance and tool life increase.Taps of high-speed steel with addition of cobalt for increase.More information about the thread forming taps Up to 100% stronger thread (higher bearing resistance).Guaranteed to provide required accuracy of the thread.Thread forming taps have a robust construction that reduces the risk of breakage.One type of taps can be used for processing various materials, as well as blind and through holes. ![]() Thread forming taps have higher resistance.Ability to handle threads in the holes with 3.5 × D depth, no problems with chip clearance. ![]() Thread forming taps are more productive than standard taps.At the end of the threaded part of the flute taps, there are small symmetrically located coolant grooves. In addition, the champfer on these taps is significantly shorter. Their main difference from cutting taps is the absence of longitudinal grooves that form cutting edges. The thread rolling profile is formed by pressing the tool into the workpiece material and extruding part of the material into the tool cavity. They are used for thread forming not only in through holes, but also in blind holes. High productivity in threading is the main advantage of cold forming taps. Compared to cutting taps, forming taps have greater strength, provide accurate threads with low surface roughness, and increase thread strength (up to 20%). These materials include: aluminum and its alloys, copper, brass, bronze with a high copper content, zinc and its alloys, low-carbon and high-plastic stainless and heat-resistant steels. To meet customers' requirements, we are able to design and manufacture taps or couplers per the samples offered.Ĭold forming taps (chipless taps, rolling taps) are recommended to be used when producing threads by plastic deformation (rolling) in parts made of non-ferrous and ferrous metals with high plasticity. Connecting taps with bent shanks by couplers could lower the possibilies of tap breakage caused by the strong torgue. Nib Tap could be connected with bent shanks by couplers, which would substantially shorten the adjusting time. This tap is used by directly screwing onto a bent shank with a thread hole. Solid welded and assembled nut taps (nib tap & bent shank tap)Ĭomposite taps are made of three parts: tap, coupler and shank. Taps optimized for handling several groups of materials, are appropriate for small- or medium volume manufacturing, when the thread is cut on various items of different materials. ![]() Taps optimized for a certain group of materials according to ISO are intended for mass production, when threads are cut on one and the same items of the same material, or when unique requirements. Our range is divided into two lines: taps optimized for handling specific groups of materials according to ISO, and taps optimized for handling several groups of materials. Taiwan Metiz Alliance offers a complete range of taps for threading any profile of different materials. ![]() Taps are appropriate for production of many thread profiles, they are suitable for all machine types with both rotating and non-rotating blanks. Tap designed and suitable for specific application and operating with high efficiency only on one material, or under certain conditions, cannot provide the same level of efficiency in other materials processing or under other cutting conditions. Important characteristics of each type of tap are: material, covering and geometry. Standard taps and tap-burnishers have different construction. This method provides productive and efficient thread cutting, small diameter particularly, due to short downtime, high speed cutting and long tool life. Thread tapping is a simple, well-known and highly effective method of obtaining the thread.
