GARANT HB 7010-1 / HB 7020

Mother Nature‘s perfect example: Wear resistanc THE SHARK TOOTH STRUCTURE, PERFECTED BY EVOLUTION, PROVIDES INSPIRATION FOR THE DEVELOPMENT OF THE GARANT TURNING GRADES HB 7010-1 AND HB 7020

Shark tooth: The combination of two components turns the shark tooth into a deadly weapon: ɾɾ Extremely tough outer layer of enameloid with Fluorapatite Ca5(PO4)3F protects against wear and tear. ɾɾ Soft dentine with high toughness on the inside of the tooth prevents chipping due to brittle fracture.

Shark tooth: ɾɾ Specially structured enameloid, deviating from the perpendicular, provides a smooth tooth surface. ɾɾ Minimum degree of friction between prey and shark tooth. ɾɾ Minimum loss of dental enamel through abrasion.

OPTIMUM COMBINATION OF HARDNESS AND TOUGHNESS Enameloid Coating

Dentine Substrate

EXTREMELY SMOOTH SURFACE

HB 7010-1 / HB 7020: Two components transform our turning grades into the superlative for machining steel: ɾɾ Wear resistant, thermally resistant outer CVD coating system consisting of Al2O3 and Ti(C,N) with maximum hardness values. ɾɾ Maximum toughness values of the inner carbide substrate prevent chipping and brittle fracture.

HB 7010-1 / HB 7020: ɾɾ Optimised surface finish of the Al2O3 coating layer. ɾɾ Minimum degree of friction between workpiece and cutting material. ɾɾ Minimum abrasion and generation of heat due to the chip sliding off the cutting insert surface.

e to the power of 4

Shark tooth: ɾɾ The extreme hardness of the shark tooth is due to grain sizes of only a few µm. ɾɾ Wear resitance due to evenly aligned crystals of the enameloid.

Shark tooth: ɾɾ Smooth transition between enameloid and dentine with the best possible adhesion properties due to (smooth) gradients. ɾɾ Organic proportion increases towards dentine-enameloid interface. ɾɾ Both components are solidly interlinked.

ALIGNED NANO-CRYSTALS

ROBUST GRADIENT MATERIAL

HB 7010-1 / HB 7020: ɾɾ Maximum hardness of the Ti(C,N) coating due to grain sizes in the nano-range. ɾɾ Higher toughness due to aligned crystal structure.

HB 7010-1 / HB 7020: ɾɾ TiN proportion of the substrate is not, as previously, evenly distributed but tapers off. ɾɾ Increased TiN proportion at the edges of the carbide substrate for optimum adhesion between substrate and coating. ɾɾ No shearing of the coating due to adapted thermal expansion coefficient of the substrate (TiN coating to TiN proportion of the substrate).

INNOVATION

Robust, sharp-edged and uniquely good! THE NEW GARANT TURNING GRADES HB 7010-1 & HB 7020 WERE INSPIRED BY NATURE'S PERFECT EXAMPLE – A SHARK TOOTH

With properties like a shark tooth perfected by evolution, the new GARANT turning grades HB 7010-1 and HB 7020 gave an impressive performance when machining steel during comparative tests. The multilayer coating system of the GARANT insert makes it possible to achieve highest cutting data and maximum reliability due to a tailor-made, innovative gradient carbide substrate – similar to a shark tooth – with a hard exterior and an elastic core.

These formula-based values are STARTING value recommendations which can be optimised depending on the machining conditions (material, clamping situation, chip breaker …). Larger corner radii rε permit improved surface quality at the same feed f. However, for larger radii and lower depths of cut (ap) increased passive forces occur (tool or workpiece deflection), which can cause vibrations.
