UFS

Running to the Top: Italian THREADING TOOLS

UFS is an Italian company specialized in the design and construction of threading tools; in particular of standard taps and special custom taps.
Over time, the company has reached a very high level in terms of product quality, above all thanks to the intense work carried out in the Research and Development plant, where increasingly specific tools for threading in specific fields of application have evolved.
The hardening of the tools is assisted internally and is certified. The surface treatments, from vaporization to painting with chromium nitride, titanium nitride, titanium carbonitride, titanium and aluminum nitride, are calibrated and customized in relation to the performance required by the product.
The UFS technical office takes care of identifying the best reference suitable for specific needs on a daily basis. Some examples, among the most important in the entire UFS production. In High Strength, designed to work materials up to 52 HRC, they are produced in PM sintered super rapid steel with high percentages of vanadium and cobalt and available with surface treatments that have a high resistance to wear and oxidation.
For stainless steel, ideal for hard-to-machine and long-chipping steels.

The basic steels are of the HSSV3 type, with 3% vanadium, or in PM sintered steel with a high content of vanadium and cobalt. The cutting geometries and the TXC treatment prevent the formation of built-up edge.

For light aluminum alloys, long-chipping copper alloys and soft magnetic iron (Fe) and aluminum alloys with silicon. Available with AZ alternating thread that avoids the formation of the chip skein with a reduced number of cuts and large unloading compartments. In cast iron, the items are made of super-rapid steel sintered in metallurgy powders with a low cutting angle and combined with an accentuated rake angle that render these types of taps suitable for working abrasive materials.

They have an increased tolerance of type 6HX and a TiAlN coating, combined with micro surface finishing processes. Also with short intake for tapping with a reduced-dimension or 25° helical discharge chamber for applications on steel cast iron (steel castings). For titanium, products come in steel sintered in metallurgy powders bearing special cutting geometries. They bear a 15° left helix for through holes and 15° right helix for blind holes. They are also available in 4HX tolerance and with TiCN treatment for processing the most demanding alloys. For nickel, the pieces have a reinforced body structure. They have a 10° left helix for through-holes and 10° right helix with chip breaker for application on blind holes and also come with a 4HX tolerance and 25° helical taps with rear tapering. For synchronised rigid tapping, in quality powder-sintered steels, the taps are rebored with h6 shank tolerance to ensure maximum precision at high cutting speed. They can also be used with thermal coil spindles. Full-thread carbide has straight cuts for machining very abrasive materials. Available with a central hole for the passage of lubricant and with TiCN surface coating. Thread mould taps in steel sintered in metallurgy powders. The coatings are combined with special surface preparation processes to minimise friction between the tool and material being worked.

Available with and without ducts, also with 6HX and 6GX tolerances and an internal lubricant type FOR central hole or with radial FORY-type outputs.
