![]() ![]() This condition has been used in brass applications with some success. NITRIDING (NQ-5)- case hardens the cutting tool surface to 66-68 Rockwell C and provides increased wear resistance with a black surface finish that acts as lubricant to reduce frictional heat and galling.īRIGHT- provides no surface treatment. STEAM-OXIDING (J-100)- provides a diamond blue/black finish that stress relieves the microstructure of the tap and provides an oxide film that reduces galling. This treatment works well in brass applications. This treatment reduces the coefficient of friction and helps prevent galling. This treatment is designed for titanium and high nickel alloys and has worked well in galvanized steel applications.ĬHROME PLATING (KF1-B)- provides a layer of hard chrome which is electrochemically deposited on the surface of the tool. CrN coating has a hardness of 75-80 Rockwell C. Titanium Nitride is the standard treatment on all Stub Jarflo taps.ĬHROMIUM NITRIDE (CrN)- provides a coating applied with the physical vapor deposition method (PVD). This treatment is not recommended for tapping titanium and has performed poorly in high nickel alloys, brass and galvanized steels. The TiN treatment is ideal for the majority of forming applications. This treatment reduces the coefficient of friction and hardens the surface to 80-85 Rockwell C. TITANIUM NITRIDING (TiN)- provides a layer of titanium, which is applied to the tap surface with the PVD method. TiCN works particularly well in abrasive and gummy materials and in high speed, high production applications. TiCN hardens the surface to approximately 90 Rockwell C and has a lower coefficient of friction than TiN. TITANIUM CARBONITRIDE (TiCN)- is a special physical vapor deposition (PVD) coating, which includes titanium nitride. There are a number of different coatings offered to maximize tap life in your material. This means no tools are required for tap changes, reducing overall downtime! MD Technology tapping tools use a ball lock system. Still not convinced? Here is a torque comparison between a leading fastner companies product and extruding and tapping with the TT2″. Roll formed tapped holes meet or exceed ANSI standard torque specifications, just like fasteners.Reduced inventory costs, unlike fasteners.Remove a process from your job cell, unlike Fasteners.Reduced manual labor, unlike fasteners.Roll formed threaded holes won’t fall out, unlike fasteners.Extruded and tapped holes can be used from both directions, unlike fasteners.There are some added benefits with tapping rather than inserts. Tap up to 180 holes per minute.**ĭo you think self clinching fasteners are better? The threads in those nuts are actually made with roll form taps as well. ![]() Get 8,000 – 10,000 holes per tap* due to the fact that your machine is doing the positioning and not a secondary manual operation. Specs up to 2B are capable with roll form threading. With roll forming, also known as cold forming, taps you not only get better thread quality you also alleviate the hassle of getting chips on your table. MD Technology TT2″ family utilizes powder metal roll form taps. ![]()
