INFO 2/17: Extention for modular system 960

HORN is extending the 960 modular system for the 845 interface by adding new cartridges to hold the S229 insert. The double-edged insert for grooving and parting off, as well as for longitudinal and contour turning, is available ex stock with various chipbreaker geometries and substrates. The maximum grooving depth of the cartridge is 25 mm with a machining diameter of 68 mm. Groove widths between 3 mm and 6 mm are available. All grooving cartridges are fitted with an internal coolant supply. Cooling takes place via the clamping finger and support.

INFO 1/17: Internally cooled inserts for grooving and parting off

The S100 single cutting edge insert and the S224 double cutting edge insert from HORN are available with internal coolant supply through the insert. The targeted coolant jet acts directly on the point of cutting, thus ensuring optimum cutting conditions. The funnel-shaped nozzle creates a coolant jet which actively supports chip formation and thus reduces the chance of chip jamming. Furthermore, this type of internal cooling significantly reduces the formation of built-up edges and fractures on the cutting edge. Unlike conventional cooling methods, this system therefore achieves higher cutting parameters, which allow the tool to be used even more economically and efficiently.

The newly developed modular thread whirling system, gives the customer a great variety of possible tool combinations, suitable for all of the most popular sliding head machines and whirling units on the market.

INFO 5/16: Tools for the micromachining industry

When machining components with diameters starting from 0.2 mm using cutting depths that often measure 0.01 mm, tools, tool systems and, primarily, cutting edge designs face extremely high requirements. In order to ensure precision chip removal even at the smallest depths, tool cutting edges must be incredibly sharp and free from break-outs, with exceptionally fi ne surface qualities.

INFO 4/16: HORN Turbo whirling® - Twice as fast with higher tool life

The newly developed HORN turbo whirling® process optimises machining during thread whirling and increases efficiency. HORN has developed cutting tools for whirling with a new cutting division specially for machining threads with a larger allowance. To this end, individual cutting edges work as pre-cutters and machine the workpiece to the defined external diameter. In the case of nine-cutter tools, the cutting division allows the machining work to be divided so that each cutting edge is subject to equal load, meaning that individual cutting edges can achieve significantly higher service lives.

INFO 3/16: Modular tooling system type 968 and 969

Working with Index and Schütte multi-spindle lathes in mind and partnering with Ernst Graf GmbH, HORN has developed the modular base carrier systems type 968 and 969 with interfaces of type 842 and 840. For Index multi-spindle lathes, there is the system type 968 for cassettes of the type 842. This means that all common cassettes of this type fit in the height-adjustable basic adapters.
