Indexable inserts machine cast iron and
steel
Indexable inserts for machining CI and steel have regularly achieved up to 75% more components per edge than competitor products, and offered improved process reliability.
The full productivity savings power of Walter GB's innovative Tiger.tec indexable insert range will be on show at MACH 2006 - not only highlighting how the inserts are available for both turning and milling, including the latest WSM 35 and WSP 45 milling and WPP turning grades, but also how the Tiger.tec application field now embraces both cast iron and steel machining The developments will allow a wide range of users to benefit from the high productivity gains achievable with Tiger.tec: the inserts have regularly achieved up to 75% more components per edge than competitor products, and in some cases doubled output, due to their improved process reliability courtesy of a high resistance to flank wear, cratering and thermal cracking

Inserts provide 75% more components per edge
A successful insert tooling range for machining irons, which have regularly achieved up to 75% more components per edge than competitor products is now being expanded into cutting steels.
Circular saws ground under 'lights out' conditions
The potential for extended production routines including lights-out operation have spurred Harrison Saw and Tool, to invest in a Woodtronic CNC circular saw blade grinder with auto Loader.
In one case - taking 3mm deep cuts on a 153mm diameter grey cast iron face plate - when Tiger.tec was applied at similar cutting data to a competitor's carbide grade (cutting speeds of 200mm/min and feed rates of 83mm/min) but applied dry rather than with water/oil coolant, the Walter insert produced 83 cuts compared with 40 before visible flank wear occurred.
Like their counterparts for cast iron, the Tiger.tec Steel inserts cleverly combine a mixture of aluminium oxide (Al2O3), titanium carbon nitride (TiCN) and titanium nitride (TiN) coatings on a tungsten carbide substrate, featuring a grey (TiCN) rake face and a golden, TiN finish (flank face) that aids wear identification.
The inserts' aluminium oxide coating is particularly effective against tribochemical wear and permits higher cutting speeds and feeds to be employed while also providing longer service life.

Rising order levels from its aerospace customer base have prompted cutting tool specialist, Techni-grind (Preston), to buy a Walter Helitronic Power Regrinder tool and cutter grinder.
Side and face cutter is a flexible slot miller
Available in diameters from 80mm to 315mm and with a wide range of insert geometries, the new F2252 adjustable side and face milling cutter offers unrivalled levels of flexibility for slot milling.
The golden TiN coating applied to the inserts' clearance surfaces simplifies wear detection and thus avoids the unnecessary waste of unused cutting edges.
The grey TiCN rake face minimises negative tensile stress and improves adhesion and toughness.
Tiger.tec Steel inserts are available in three grades; WPP10, WPP20 and WPP30, and eight ISO insert shapes with negative angles, covering the complete range of workpiece materials from unalloyed structural steels to low-alloyed and case hardened steels, as well as high-alloyed quenched and tempered, high-strength steels within the range 1,300N/mm2.
WPP10 is designed for high cutting speeds and favourable machining conditions; WPP20 is the universal grade covering 80% of all applications; and WPP30 is designed for difficult machining conditions and interrupted cuts.
