Turning - Insert grades Insert grades The Seco range consists of coated (CVD and PVD), uncoated, and cermet grades. The designation of the grades indicates a ranking regarding their wear resistance and toughness qualities. All the grades are also classified according to ISO (R M, K, N, S, H). The black areas In the chart indicate an insert's main ISO application groups and the white areas Indicate other supplementary application groups.

Turning - Insert grades Intended for medium-roughing and roughing of steel and alloyed steel requiring a very high degree of heat and wear resistance. Intended for general turning of steel and alloyed steel. The high wear resistance offers high speed capability TP2500 is Intended for a wide range of turning applications In both steel and stainless steel and Is also a good choice for cast Iron. The wear resistance and edge strength together with the high versatility make the grade the first choice In a large number of applications. Intended for rough or Intermittent turning In steels and stainless...

Turning - Insert grades

Turning - Insert grades Avery hard PVD-coated super fine grained grade intended for machining of steel components with both hardened and soft areas. The superior edge toughness provides excellent performance In Interrupted cuts in hardened steels as well as In hard surface removal. Nanolaminate based on TI-AI-SI-N Hard micrograin principally Intended for finishing operations in superalloys and titanium alloys. Also per- forms well In finishing operations on stainless steel. Tougher alternative to TS2000. TS2500 Is principally Intended for roughing operations in superalloys and titanium alloys....

Turning - Cutting data Cutting speed The recommended cutting speeds (m/min) in the tables are estimated for 15 minutes tool life for Seco material groups 1-7 and 12-15, and 10 minutes tool life for Seco material groups 8-11. Use the tables beginning on page 501 to classify the workplece material into a Seco material group. For more accurate recommendations with other combinations of cutting depths and nose radius and other feed rates than those used In the tables, use the Se- color Turning calculator, please see www.secotools.com.

Secomax – PCBN Introduction Polycrystalline Cubic Boron Nitride (PCBN) is a material which is sintered at extremely high pressure and high temperature into a wear-resistant material with properties close to those of diamond. Due to the hot hardness, oxidation resistance and fracture toughness of the material, inserts made of PCBN have excellent edge strength and long tool life in machining operations on hard ferrous materials and pearlitic grey cast iron. Secomax PCBN inserts are suitable for machining: • Hardened steel (including hard-facing alloys) • Pearlitic grey cast iron • Chilled and white...

Secomax - PCBN Geometry recommendations Strong cutting edge geometries are always preferred. • Negative cutting geometry • Chamfered cutting edge Sharp positive cutting edge geometry can be advantageous • Finishing of small hardened bores without Interruptions • Finishing of unstable components without interruptions • Finishing of pearlitlc grey cast iron Edge preparation E25 = Extra honed, Intended for Nickel-based S25 = Chamfered and extra honed Intended for PM material Chamfer size and angle Plunge Turning The vast majority of heat treated components in the metalworklng industry are machined...

Secomax - PCBN Maximum depth of cut recommendations Round inserts The tool cutting edge angle Is limited to 75° resulting In maximum True tip length (TTL) in mm per nose radius (rs) and tip type

Secomax - PCBN, Grades The Secomax PCBN range of grades consists of both coated and uncoated The application areas for the Secomax grades are shown below. The black areas In the chart Indicate a grade's main ISO application groups and the white areas Indicate other supplementary application groups.

Secomax - PCBN, Grades Insert grades Solid, brazed tips (single sided) or sintered layer • For high speed light continuous to moderate interrupted cuts In hardened steel • (TI,Si)N PVD coating developed for high speed machining. Solid, brazed tips (single and double sided) • First choice for continuous to moderate Interrupted cuts in hardened steel • New (Ti,SI,AI)N PVD coating developed for high speed machining. • New unique superalloy binder. Brazed tips (single sided) or sintered layer • For light continuous to moderate interrupted cuts In hardened steel

Secomax - PCBN, Grades Insert grades Brazed tips (single sided) or sintered layer • Ideal for high surface requirements. • Tougher but slightly less wear resistant alternative to CBN 10 and CBN 100. • For Interrupted cuts in hardened steel (ap <0,5 mm). Brazed tips (single sided) or sintered layer • For aggressive Interrupted cuts in hardened steel (ap<0,5 mm). • (Ti,SI)N PVD coating developed for high speed machining. Solid and brazed tips (double sided) • For high speed continuous cuts in nickel based superalloys (ap <0,5 mm). • New unique whisker reinforced binder. Solid, brazed tips (single...
