Horn Milling System 406 with Wiper Geometry

Milling System 406 with Wiper Geometry                     

Paul Horn GmbH has extended the 406 tangential milling cutter system to include an insert with wiper geometry for finishing. The new insert has been developed in response to demand from Horn’s customers, reflecting the fact that surface quality requirements are constantly increasing. The new geometry produces very high surface qualities, even at high feed rates, resulting in shorter machining times. Moreover, the geometry makes it possible to reduce the need for subsequent grinding processes.

The single-edged finishing insert is used in the 406 system’s 90-degree shoulder mills. Only one insert with wiper geometry is required in the tool body. The remainder may be standard 406 system indexable inserts. The wide finishing insert is available in grade AS4B for the workpiece material groups P and M, and in grade AS46 for workpiece material group K.

EMO 2019: New Coating IG35 from Horn

New Coating IG35 with High Heat Resistance

The new IG35 insert coating allows Horn to offer high performance and long tool life when machining stainless steels, titanium alloys and superalloys. In combination with the 3V and FY geometries, the aluminium titanium silicon nitride coating prevents the formation of built-up edges due to the low coefficient of friction. Thanks to HiPIMS coating technology, the coating exhibits very smooth properties and high heat resistance. Furthermore, the tool coating is free from defects such as inclusions or other coating faults at the cutting edge.

Horn adapts the coating system, the chipbreaker geometries and the micro-geometries to applications such as internal and external grooving, longitudinal turning, circular interpolation milling and solid carbide milling. The user can achieve higher cutting parameters, enabling a shorter cycle time, which in turn has a positive impact on unit production costs. The use of the new coating also leads to higher surface qualities.

The IG35 coating is available for the S100, S101, S224, S229, and S274 grooving systems as well as for the circular interpolation milling and solid carbide milling systems.

Please contact us for any information you need on the new coating.

 

 

EMO 2019: New Parting Off Solutions along the Y Axis

Efficient Grooving using High Cutting Parameters

Paul Horn GmbH is offering new tool holder variants for the S100 system for parting off with the feed movement along the Y axis on turning/milling centres. This method enables a very effective grooving process with high cutting parameters, resulting in shorter machining times. Furthermore, there is the option to part off large diameters with a compact grooving tool holder as well as to part off with narrower groove widths.

Large moments of force occur, particularly when parting off workpieces of larger diameter. The space available in a machine often does not allow tools of large cross section to be used. With the new arrangement of the insert in the tool holder, the cutting forces are diverted to the main cross section of the grooving tool. This results in increased rigidity of the system as a whole for a given cross section of the grooving tool holder and allows higher feed rates to be used. The force in the longitudinal direction of the tool means narrower holders can achieve the same system rigidity. In modern generations of turning and milling centres, parting off with the new grooving tools causes the cutting force to be diverted in the direction of the spindle, meaning higher rigidity of the overall.

Horn is offering two holder variants for the parting off process. For the 842 and 845 modular grooving system, there is a cartridge with cutting widths of 3 mm (0.118″) and 4 mm (0.157″). There is also a reinforced grooving blade, also with widths of 3 mm (0.118″) and 4 mm (0.157″). Both variants are equipped with an internal coolant supply via the clamp and through the support. In addition, the S100 system provides an option for direct cooling through the cutting insert. The maximum groove depth (Tmax) is 60 mm (2.362″). The tried-and-tested grooving insert of the S100 system is used, which is available in various substrates and geometries.

EMO Preview: New Insert Clamping System for Horn Supermini

Hall 5 Booth A54

Horn has developed a new tool holder for its Supermini type 105 grooving and boring tools. In the new design, the process for clamping the carbide insert uses a tensioning wedge on the face rather than the circumference of the tool, as was previously the case. This enables the insert to be held in place with more force, which makes the entire system more rigid. Additionally, the new clamping design results in a higher level of repeatability when changing inserts and allows for better use of the space available for mounting it due to the face clamping concept. This is a significant advantage when working with Swiss-type lathes, as it enables users to change the insert without removing the tool holder.

The Horn Supermini tool system is able to bore holes from 0.2 mm to 8 mm in diameter. With over 1,500 varieties available as standard, there is a solution to suit every user. In addition to boring, the system is designed for grooving, chamfering, threading, broaching and other machining operations. The cutting geometries and the substrates can both be adapted to the materials being machined.

Milling instead of Polishing

Horn MKD Ball Nose Endmills
Horn MKD Ball Nose Endmills

Paul Horn GmbH is expanding its tool range for brilliant-finish milling. The monocrystalline diamond-tipped (MCD) ball nose end mills are intended for machining non-ferrous materials in the tool and mould making industries. Milling with MCD-tipped tools saves on polishing processes when producing free form surfaces. The new, larger diameter variants reduce machining time, guarantee compliance with the tightest tolerances and produce surface finishes in the nanometer range.

Horn offers the expanded portfolio of MCD ball nose end mills from stock.  Diameters of 6 mm, 8 mm, 10 mm, 12 mm and 16 mm allow a broader range of applications to be covered. All variants are single-edged and feature an internal coolant supply. The solid carbide tool shanks enable vibration- and oscillation-free machining.

The range of applications for brilliant-finish milling is huge. In the tool and mould making industry in particular, the method saves on polishing, while also increasing quality in terms of precision, contour accuracy, flatness and surface finish. It is therefore used in applications where the surface quality of the mould needs to be matched by the finish of the parts being produced. For example, they include PET blow moulds and chocolate moulds as well as applications in the medical technology sector. In addition to brilliant-finish milling, Horn also offers solutions for brilliant-finish turning with MCD tools.
