Rod Blanks
Kennametal offre un'ampia selezione di metallo duro di tungsteno a qualità micro-granuli e submicro-granuli che sono ideate per resistere a calore estremo, vibrazione ed usura da impatto. Our products are sinter-HIP processed for ISO 9002 certified manufacturing facilities.
We offer:
- pressed and extruded unground, ground and polished rods with or without chamfers
- rod products that can be ground to h6 tolerances
- a variety of grades that provide exceptional wear and impact resistance
- grades for use in end mills, reamers, drills, countersinks, engraving tools, routers, and other rotary tools
- grades for use in a broad range of applications in almost any material
Solid Rods and Rods with Coolant
Kennametal manufactures 12” (330mm) length rods with single hold, straight two-hole, and 30° spiral two-hole coolant holes, in diameters from 5.8mm to 25.4mm. High-performance gun drill rod blanks are available.
Cut-to-Length (CTL) Rod
Offriamo una delle linee più ampie e complete dell'industria per quanto riguarda i prodotti rettificati tagliati su misura. Premium grades, standard and micro-finished surface finish, and h6 ISO diameter tolerances in inch and metric lengths and diameters. Special preform features are available, including male center, female center, ballnose, step reduction, and shaped points.
Metal Cutting Tool Blanks
We have a complete line of metal cutting tool blanks in a wide selection of tungsten carbide grades with binders ranging from 5.5% to 25%, and grain sizes to suit your application. Offiramo qualità di raccoglitori di cobalto in metallo duro di tungsteno per la maggior parte delle applicazioni usuranti e anche mix di metallo duro di tungsteno con additivi di metallo duro di titanio per prevenire l'usura stirante metallo-metallo.
Inserti grezzi
Produciamo una gran varietà di tipologie di pezzi grezzi quali K1000 e STB per utensili brasati e utensili di forma, e inserti grezzi standard graduabili come SNR, SPR, TNR, TNRA, TNRC, TPR, TPS, UVDB oltre a geometrie speciali progettate su misura. La maggior parte degl'inserti sono pressati per entrare nel bordo minimo di affilatura, in modo tale da mantenere i tuoi costi di molatura bassi.
Grezzi piatti
Produciamo una vasta varietà di tipi di grezzi come K1000 fino alla K6000, e grezzi STB, in più geometrie speciali variabili ideate e personalizzate secondo le tue specifiche.
Gear Cutting Blanks
We manufacture tungsten carbide hob blanks and specialty gear cutting blanks that are used to make spur and helical gears. They have excellent metallurgical quality and geometrical accuracy and can be ground and reconditioned.
Grezzi STB
Our hob blanks are designed for even, consistent cutting with better overall productivity and efficiency in a variety of gear materials.
Kennametal hob blanks are available in these ISO P and K grades:
| Qualità: | Cobalt % | WC % | Other Carbide % | Hardness HV30 | Dimensione dei granuli |
| KF1 | 6 | 93.7 | 0,3 | 1740 | Fine |
| KMS | 10 | 89.3 | 0.7 | 1550 | Fine |
| PFF | 10 | 74.3 | 15,7 | 1600 | Fine |
KF1 and KMS are micro-grain grades with an average grain size in the raw material < 1μm. Use grade KF1 when high wear resistance is required. Use grade KMS when very good bending strength is needed. Grade PFF contains a gamma phase, with high elevated-temperature hardness and edge retention.
