Products

The “standard” UFS tap covers more regular user needs, in compliance with DIN standards. The current catalogue (31-2020) contains over 5,000 products. UFS also produces threading tools upon specific request from the customer. Indeed, the production of this type of tools represents around 30% of company turnover.

 

UFS tools are divided into 3 product lines, with increasing functional performance and durability to offer the customer the opportunity to achieve better economies of production. There is the LINE range of HSSE steel tools, the PLUS in steels with higher cobalt content and the TOP series representing the spearhead of UFS production with tools designed for machining specific materials.

 

High strength items for machining materials up to 52 HRC, the taps are in steel that is super-rapid sintered in metallurgy powders with high percentages of vanadium and cobalt, available with surface treatments offering high resistance to wear and oxidation.

Stainless steel is ideal for pieces that are difficult to work and with long chips. The basic steels are HSSV3 type, with 3% vanadium, or steel sintered in metallurgy powders with high vanadium and cobalt content. The cutting geometries and TXC treatment prevent the formation of the built-up edges.

There are light aluminium alloys, long-chip copper alloys and sweet magnetic iron and aluminium alloys with silicon. Items are available with AZ interrupted threads that prevent the formation of the skein shavings with a reduced number of cuts and ample offcut 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. There are similarly K-ROLL taps for high-output applications on medium-/high-strength materials.

 

The tempering of the tools is fully assisted and certified by UFS. Surface treatments (PVD) range from vaporisation through to coating with chromium nitride, titanium nitride, titanium carbonitride, titanium nitride and aluminium, or else formulated and calibrated by UFS in relation to the performance required by the tool.
