  • The newly developed tool system enables highly economical and productive milling performance. Each precision-ground indexable insert offers four usable cutting edges. This means that the user no longer needs different inserts to equip the milling cutter body. Horn offers the positive inserts with round chip breaker groove in the new grade RC4G. This grade enables high cutting performance during the milling process. The M475 system complements the existing Horn milling systems M310, 382 and 383. The special surface treatment of the milling cutter bodies offers a high level of protection against abrasion from chips.

    The cutter bodies are available from stock as side milling cutters, shell milling cutters and screw-in milling cutters. The shell and screw-in milling cutter variants are equipped with an internal coolant supply. Horn offers the side milling cutters in diameters from 80 mm to 200 mm. The cutting and grooving width is optionally 5 mm (0.197“), 6 mm (0.236“) or 8 mm (0.315“). As shell mills, the tools are available in diameters from 63 mm (2.480") to 200 mm (7.874"). The groove widths are the same as for the side cutter variant. The screw-in cutters are available for groove widths from
    5 mm (0.197") and diameters from 40 mm (1.575") to 63 mm (2.480") as standard. The effective number of teeth of all variants depends on the respective diameter. For example, it is zeff = 2 for the 40 mm (1.575") diameter shell mill and zeff = 13 for the 200 mm (7.874") side cutter. The large number of effective cutting edges also contributes to the economic efficiency of the new M475 milling system.

  • With the new RC2 and RC4 coatings, Paul Horn GmbH is exhibiting new developments in the field of high-performance tool coatings. The high toughness and hardness allow the machining of steels at high cutting speeds and lead to a significant increase in tool life. The high temperature resistance enables productive use in dry machining as well as with minimum quantity lubrication. Numerous tool systems are available from stock with the new HiPIMS coating. In-house coating enables fast delivery times even for special tools.

    Horn is constantly investing in new and modern technologies. In 2015, the company CemeCon delivered the world's first of three HiPIMS systems to Horn. The High Power Impulse Magnetron Sputtering technology brings specific advantages and new possibilities in the coating of precision tools. It enables the build-up of dense, compact coatings that are very hard and tough. The coatings have a homogeneous structure and uniform coating thickness even if the tool geometry is complex. Research and development of new and existing coatings and technologies is a central component of success. Horn employs a team of engineers who work exclusively on this subject. Since in-house coating started, research and development projects have been carried out in cooperation with equipment manufacturers.

  • Paul Horn GmbH has developed a new chip breaking geometry especially for the 108 Mini tool system. The I geometry is primarily intended for use when materials with poor chip formation properties are being machined. The geometry is suitable for copy turning, longitudinal turning and facing. Particularly if infeed rates are small when machining steel and stainless steel, the tool system demonstrates efficient chip control. This leads to higher process stability and also to longer tool life. Horn has also developed the new I geometry to improve machining of lead-free materials. Due to poor chip formation, these materials are likely to pose even greater challenges for the user in the future. For small infeed depths, Horn also offers the inserts with small corner radii from 0.05 mm (0.002"). Corner radii from 0.05 mm (0.002") to 0.2 mm (0.008") are available from stock as standard.

    The screw-mounted inserts of the Mini system are among Horn's core products. The tool system is mainly suitable for turning applications. The precision tools have proven themselves especially suitable for boring and internal grooving. Due to the low-vibration carbide tool carriers, the inserts produce good surface finish even with long overhangs and ensure high process reliability. The extensive portfolio of the Mini system offers inserts in various sizes for different inside diameters, geometries and substrates as well as with CBN or diamond edge coating.
