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.

Please contact us for any information you may need on these solutions.

 

EMO Preview: New Insert Clamping System for Horn Supermini

Paul Horn GmBH at EMO 2019
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.

 

 

EMO 2019 : Knoll Showcases Global Competence

KNOLL Maschinenbau at EMO 2019
Hall 7, Booth C34.

At EMO 2019, the world’s premier trade show for metal processing, KNOLL Maschinenbau will present itself as a global player, whose products –  Conveyors and Filtration Systems, Pumps, and Transport Systems – are widely used in plants all over the world.  KNOLL supplies not just innovative machine tool components, but also large turnkey central systems for coolant, lubricants and chip management.

  • Knoll Central Systems

KNOLL’s core business – systems for cooling lubricant and chip management – has taken on new dimensions. In addition to outstanding standard components for machine tools, there are also numerous large Central Systems, which KNOLL has delivered to metal processing production operations all over. These systems can supply 30 or more machines with up to 12,000 l/min of extremely clean cooling lubricant. Modular system technology enables them to achieve still greater total output. At EMO visitors can get an impression of this expertise.

In Hall 7, Booth C34, KNOLL will present cooling lubricant in the form of a stand-alone solution for two-stage cooling lubricant filtration.  After the show, this machine will be used by a customer in an HSS grinding shop. It contains a 240/AK5 MicroPur®filter, which is supplemented by a KNOLL KF 400-E compact filter with an endless filter belt. It handles the task of chip pre-separation, making superfine filtration easier.

Innovative Standard Components

The basis of every large system is innovative standard components that are also used in many individual machines. These include the modular superfine MicroPur® filter, which is designed to remove residues from grinding processes, whether carbide metal, HSS or Cast particles. At EMO, KNOLL will present the MicroPur® in the 120-F version, which contains two back flushable filter elements for approx 120 liters of filter capacity. It is particularly cost-effective when working with the integrated KNOLL AK5 automatic concentrator, which reduces the carryover of oil and can ensure a residual moisture content in the settled material of less than or equal to 10%.

For over a year, KNOLL Maschinenbau has offered the LubiCool® mobile high-pressure station for use on short and long automatic lathes. It supplies cooling lubricant at up to 150 bar, which ensures short processing times and longer tool service life for short-breaking chips. Machines are made suitable for even the most challenging of machining processes, such as machining high-alloy steels or titanium. The built-in belt filter with a filter fineness of up to 20 µm guarantees the cooling lubricant purity that is required for high-pressure applications.

At EMO, the “big brother” LubiCool® L will celebrate its premiere. It is designed for larger lathes and small and medium-sized processing centers that require higher flow volumes and flushing processes. Here, high-pressure pump KTS 25-50 can be used with a TG 30 centrifugal pump for flushing. Optionally available for integration is a BS 40 lifting pump, which guarantees independent high-pressure and supply systems.

Both LubiCool® variants use the new SmartConnect operating concept, with which a small industrial PC is connected to the PLC system. Using a 7″ touch display, the user can access the system, visualize states, check parameters, and thus change to manual mode.

Refreshingly Different – the Modular Machine

Based on the structural principles of a processing center and an ideal presentation platform for KNOLL OEM products: the Modular Machine.  KNOLL will display its Plate Conveyor design, as an example, whose distinguishing feature will be plates that are joined hinge-free so that it is suitable both for chip removal for wet and dry processing, as well as conveying small sheet metal parts.

For applications that create very fine, lightweight chips, KNOLL has developed another complementary solution: an attached, self-priming BS 40 dirty water pump which conveys cooling lubricant that contains chips into the chip separator, using the cyclone principle to separate the chips from the cooling lubricant and store them in the ascending area of the conveyor belt. The pre-cleaned coolant flows directly to the filter system.

This is present on the Modular Machine in the form of a KF 150/650 Compact Filter. The universally applicable tower model belt filter saves space since the filter elements sits on the tank.

As a conveyor alternative, the Modular Machine includes an RKR return pumping station with chip reducer, which will demonstrate how cooling lubricant and chips can be transported away from the machine reliably, cleanly, and in space-saving fashion to a central separator/filter.

At EMO 2019, the Modular Machine will, for the first time, contain a fluid cabinet, which includes a pressure boosting system with KTS screw pump, valve technology, and control filter.

MMS instead of Cooling Lubricant

For many chipping applications, Minimum Quantity Lubrication (MMS) is an alternative to using cooling lubricant. For this, KNOLL offers the modular ControLube MMS system, which works with injector technology and microprocessor control. The system developed by KNOLL already delivers a particularly fine aerosol within 0.1 seconds, which provides for improved process conditions, shorter processing times and lower costs. A core property of this MMS system is the oil quantity that can be regulated regardless of the air pressure; it is also available in the simplest ControLube model. Depending on requirements, the system can also be retrofitted process-specifically with additional modules and, for example, with a controllable air pressure of up to 20 bar.

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.
