EMO Preview : Economic Advantages with Form Tools

Paul Horn GmBH at EMO 2019
Hall 5 Booth A54

Turning with form tools allows customers to benefit from economic advantages in series production. Horn offers customised carbide form inserts based on the 117 tool system for machining diameters from 16 mm upwards on turning and mill-turn centres. The patented, precision insert seat of the 117 system guarantees high concentricity and minimal axial runout as well as high repeatability of insert exchange to within microns. The precision-ground cutting edges achieve a high level of accuracy and surface quality. Financial savings are achieved due to the possibility of re-tipping, lower tool costs and reduced machine downtime. The internal coolant supply to both cutting edges via the round shank cools the contact zone and carries the chips away efficiently.

Horn offers the tools in profile widths (w) of 16 mm, 20 mm and 26 mm. Special profiles are precision ground to suit the application. The maximum profile depth is tmax = 17 mm. The maximum profile width is w = 26 mm. The insert coating is specially selected for each application and is available for material groups P, M, K and N. The round shanks are available as standard with diameters of 16 mm, 20 mm and 25 mm in the A and E designs. All variants have an internal coolant supply.

 

Gear Machining Solutions with Horn Tools

Complete machining of a Cyclo-Palloid Gear with HORN Tooling:

Horn has developed highly efficient gear machining processes for the Gear Industry.  We showcase here an example of machining a Cyclo-Palloid Gear with a HORN tooling solution.  The wide profile is opened with a custom multi-row M279 milling cutter, then the flanks are alternately roughed. The root diameter is machined with a DS cutter, the flanks are finished with a DGVZ tool and the sharp edges are chamfered with a DS cutter.

 

 

We showcase below another example of Gear Cutting with Horn Tools, from the machining of the Cyclo-Palloid Gear Teeth to the machining of External and Internal Splines by Broaching and Power Skiving.

Horn Mini 108: Targeted Chip Breaking

We are pleased to showcase the HORN Mini system 108 with threading geometry suitable for turning ISO metric internal threads in partial and full profile. The chip breaker geometry enables the production of short chips, even with hard-to-cut and long-chipping materials. This reduces the risk of chip build-up and prevents swarf from becoming entangled around the tool holder, increasing process reliability. Targeted chip breaking also makes it easier to handle chips.

Long Tool Life and Greater Flexibility for the 64T Grooving System

 

Horn has developed the new IG35 coating for economical machining of Stainless Steels. Based on the latest technology, this new coating offers high hardness and a low coefficient of friction. Due to the thicker coating required when machining stainless steels, standard types based on aluminium titanium nitride (AlTiN) are not always the most economical solution. Use of state-of-the-art coating technologies increases the hardness and lowers the friction.

As a result, IG35 demonstrates significant advantages when machining stainless steels, reducing the risk of built-up edges and offering longer tool life. Compared with existing coatings, IG35 came out on top in wide-ranging tests, with tool life doubled or even tripled in some cases. A copper-coloured top layer helps to improve wear detection.

Horn is also expanding its existing tooling systems and is now offering new solutions for its S64T grooving system tool holders. In addition to square shanks in various designs, users can now also clamp the six-edged indexable insert in cartridges.

These are available from stock in a variety of cutting widths for the insert seat. The clamping cartridges are used in particular with HSK holders and the 960 modular system offered by Horn. The tried-and-tested S64T grooving system is available in a variety of cutting widths. The system can easily be adapted to different machining tasks using various standard chip breaker geometries. The insert is available with a variety of coatings including the new IG35 variety.
