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.
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.
Our portfolio of products for boring now includes diamond-tipped tools with CVD-D and PCD cutting edges. These tools are used for boring, copying and grooving when working with sintered carbide, ceramics or abrasive plastics. They are also used for machining non-ferrous materials which are either highly abrasive due to their silicon content or have a tendency to exhibit chipping problems and form built-up edges. The chip geometry, which has been specially developed for this purpose, solves virtually all machining problems caused by uncontrolled formation of stringy swarf.
HORN has developed the new DA62 milling system for corner, face and plunge milling. The system from the Tübingen-based precision tool manufacturer uses a new six-edged indexable insert. Both sides of the insert can be used and it has three axial and radial cutting edges on each side. The precision-sintered, trigonal insert boasts a large core cross-section and maximum cutting length. The design of the cutting edges produces a positive cutting geometry despite the negative insert angle.
The new 262 tool system has been specially developed by HORN for cam-controlled lathes, with indexable inserts for holders with 6x6 and 8x8 mm cross-section.
The hard-milled insert seat ensures excellent stability, the ground contact surfaces of the indexable inserts ensure exceptional precision and two fastening screws ensure stable clamping. The system allows the centre height, width and length to be positioned precisely. A lateral insert seat offers maximum freedom when designing the cutting edge.
21 different cutting edge shapes are available as standard:
- for grooving with a width of 0.8 mm or more
- for grooving and longitudinal turning with a width of 0.8 mm or more
- or longitudinal turning: forwards and backwards
- and for face turning
The modular grooving system from HORN for grooving cartridges based on the systems interface 845 and 842 consists of:
Basic toolholder for turrets with BMT / MAZ connections or VDI holders for turrets and Star turrets
Basic toolholders for mill-turn centers
The modular system kit has a selection of basic toolholder for turrets with BMT connections, based on standard machine types. Alternatively VDI basic holders and basic toolholders for mill-turn centers are available in various sizes.
The matching grooving toolholders with integrated coolant supply allow the cartridge heights to be adjusted and their fastenings to be set in a normal or overhead position, on the left or on the right of the grooving toolholder.
The cartridge systems with system interface 845 and 842 serves as the holder for the S100, S101 and S224 grooving insert systems with a range of geometries and substrates. Grooving widths of 1.2 mm - 4 mm are available with grooving depths up to 55 mm. The cartridges are equipped with an integrated coolant supply in versions for clamping finger and support cooling.
The newly developed HORN turbowhirling® system optimizes the thread whirling process and increases efficiency.
HORN turbowhirling® can be applied to single-start and multi-start threads and profiles. What's more, during this process, the S271 precision-ground double-edged indexable inserts are tailored to the respective thread profile and the material to be machined. The indexable inserts are clamped in positive-fit, extremely stable insert seats either in the new modular whirling heads with optimized handling during insert replacement or conventionally in the Mono block tools.
When machining components with diameters starting from 0.2 mm (.008") using cutting depths that often measure 0.01 mm (.0004"), tools, tool systems and, primarily, cutting edge designs face extremely high requirements.
In order to ensure precision chip removal, even at the smallest depths, cutting edges must be incredibly sharp and chip free, with exceptionally ﬁne surface qualities. The machines employed in micro-machining usually offer signiﬁcantly less space for toolholders, requiring the use of holders designed speciﬁcally for them. Toolholder design featuring internal coolant supply guarantees maximum performance.
HORN's thread whirling technology with 6 or 9 effective cutting edges with whirling cutters type M271 is a highly effective and economical system to produce single or multi start threads and profiles. Due to very short machining time, the process of thread whirling much more cost effective when compared to conventional threading practices.
The newly developed modular thread whirling system gives the customer a great variety of possible tool combinations that is suitable for most popular sliding head machines and whirling units on the market. The high precision indexable inserts type S271 offers the possibility of conventional whirling using 6 inserts per tool or HORN Turbowhirling® having 9 inserts on the tool (3 roughing and 6 finishing inserts).
The funnel-shaped nozzle creates a coolant jet, which supports chip forming and thus reduces the chance of chip build-up.
This type of internal cooling largely prevents the formation of build-up edges and premature chipping of the cutting edge. Unlike conventional cooling methods, this system achieves higher cutting parameters, which allow the tool to be used more economically and effectively.
The insert S100 with chip geometry .3V and HP65 coating is specifically designed for grooving and parting off, stainless steel materials.
Supplying internal coolant to the cutting point guarantees efficient cooling and boosts chip flow.
The system has been expanded to include the 4 mm (.157") cutting width and can achieve grooving depths of up to 20 mm (.787"). Both one-edged and two-edged straight or full-radius inserts are available in the additional cutting widths. Indexable inserts have a "neutral" design and can therefore be used in left and right tool holders.
The 64T six-edged indexable insert is the latest addition to the HORN family of high performance tooling. The 64T insert is precision sintered and available in widths up to 3.29 mm (0.130") with geometry .00. As a neutral grooving insert, it can be used on either the left or the right in square shank holders with internal cooling. The holders measure 16 x 16 (0.630" x 0.630"), 20 x 20 (0.787" x 0.787") or 25 x 25 mm (0.984" x 0.984").
The 64T insert supports grooving depths of up to 3.5 mm (0.138") and a maximum workpiece diameter of 65 mm (2.559").
The new EG55 high-performance coating considerably improves the tool life and makes the grooving insert a perfect all-around choice for machining steel as well as a wide range of other materials.
Setting new standards with a new coating, new substrate and new micro-geometry for boring holes between 0.2 mm and 6.8 mm.
