Tooling systems

The Super Mini receives type 105 from Horn to the AMB 2016 new high-performance variants. He uses during the turning of holes between 0.2 mm and 6.8 mm set new standards with new coating, new substrate and new micro-geometry. Horn thus follows the desire of customers with increasing proportion of stainless steel and high alloyed and inhomogeneous steel grades, their production throughput speed want.

For drilling diameters from 0.2 mm to 6.8 mm the tool system triggers super mini type 105 with well over 1,500 cutting versions many different machining tasks. It proves its strengths in a wide range of applications in boring, grooving, chamfering, thread turning, axial one stinging, boring, facing and slotting small and smallest diameter. The previous range, the editing of steels, cast iron, non-ferrous metals, exotic materials with high hardness and manipulating small and small parts with a special micro geometry, is now supplemented by high-performance variants to the Speed up the processing of demanding steel qualities as stainless steel, high alloyed or wavering inhomogenous.

Significant increase in booth time
Extensive test series with comparisons to previous substrates and coatings showed a significant increase in booth time on multiple. This certainly in the background it provided the "high performance super mini" customers for test purposes. The documented results of customer trials show that the new variety EG35 is superior to the previous varieties by far: the service life to 60 percent increased material Co28Cr6Mo0, 2 C with 1,000 N / mm². The material 11SMN30 + C, the lifetime even more clearly rose to over 100 percent, and in the material 40CrMoV13-9.

New coatings improve the life

Especially tough materials make the highest demands on cutting tools, particularly for small and small parts in technical and economic terms. For these applications, tools of the product series Super Mini edit holes from 0.2 mm diameter - developed Horn the coatings EC3 and ec5.
A particularly smooth layer is generated with the coatings differing by the substrate and the coating thickness, which reduces the heat input into the tool, especially at the cutting edge, due to less friction. A golden coating ensures a better recognition of the wear layer at the end. Numerous test series, complemented by the highly precise, reliable work processes-based practical experience by customers, confirmed the capability of the new coatings EC3 and ec5. They got up to 100 per cent compared to the previous coating material-dependent as time increases.
The new coatings have been developed for the tooling systems Super Mini, mini and 312. Super Mini is especially to the boring and grooving with bore diameters ≥ 0.2 mm. For similar operations, the tool system mini diameter 6,0 mm be used. The three dashing inserts of the system 312 are also used, and cutting off in the external machining, as well as similar edits from bore diameter of 46 mm.

Development of the modular cutting systems

HORN extends its technical system the cassette system 842 with smaller dimensions for machining small workpieces. The system is suitable for the cutting off of different steel grades and scores with very high rigidity and efficient cooling.
The cassettes 842 are components of the modular system of stinging 940 consisting of basic holder, stinging retaining piece and tape. For the user benefits of the flexibility in the combination of the components. The stinging retaining pieces are connected to the basic holder depending on the type of machine and application in different lengths.
Thanks to the compact design, you can easily insert the cutting tool in various types of machines. HORN has developed with special connectors for lathes by Traub and index initially the novelty. The variant 842 S100 cutting program is suitable for economic cutting-off machine steels, high-strength and stainless steels.
The cassette for use in lathes with smaller work rooms is secured on both sides. Depending on the editing task the cutting of the S100 type in different widths, geometries and coatings is available. The screws clamping of the cutting edge allows a simple tool change with high repeatability.
The cutting tool works with internal coolant supply via support cooling down and clamping finger cooling from above. The coolant Jet acts directly on the cutting edge and ensures optimum work results. Compared to conventional cooling systems from the outside, this type of cooling ensures higher cutting parameters and longer tool life. The system allows the user to an economic usage.
The cartridges of the type 842 were developed with the aim of: maximum stiffness. Consequently the advantages compared to swords in flatness and surface quality will be. Facing the parting surface may be waived the additional operation. The surface of the workpiece has a very flat parting surface with very low roughness after processing with the system of 842. HORN offers the cutting tool with depth of Tmax = 22 mm and 34 mm = Tmax on. The system especially when machining of bar stock in production comes into its own.

Horn thread whirl technology single - and multi-Start external threads and profiles are manufactured with six or nine dashing tools of the type M271 efficiently and economically. Very short processing times, thread whirling lathe machines offers significant advantages over the thread turning. The newly developed modular tool system offers plenty of combinations, the customer via ground carrier and ring boxes suitable for the various lathe machines existing in the market and drive units. It can Turbo fluid process with nine indexable inserts per ring cassette (of which three spurs and six with the very precise system S271 conventionally with six or nine indexable inserts per ring tape or with the newly developed Horn Work finished Schneider). About the Werkzeugkonfigurator on the site of the Horn the matching engine drive units and tool combinations can be found easy. The system about the new HCT cutting data calculator available, which is also available through the Horn website provides the correct cutting data.
