Turning insert offers double the cutting
edges
A double-sided indexable insert combines the advantages of positive and negative inserts and offers tool life savings of up to 30% and a 10% drop in required spindle power.
Walter GB will be showing its Xtra.tec Turn double-sided indexable insert at the UK's MACH 2008 machine tool show Walter GB said that the insert offers high productivity and low tooling costs by combining in one the advantages of positive and negative inserts

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.
Tool grinder meets rising aerospace demand
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.
The new insert provides double the number of cutting edges when compared with conventional positive indexable inserts.
In addition, Xtra.tec Turn generates tool life savings of up to 30% and, importantly said Walter, uses up to 10% less spindle power requirements.
With a high positive rake angle for soft cutting action and low cutting forces, as well as unhindered chip flow, Xtra.tec Turn is ideally suited to machining thin unstable parts as well as deep internal applications.
By following the market preferred route of double-sided inserts for rough machining but also applying the high tool rakes found on single-sided inserts, in developing Xtra.tec Turn Walter needed to overcome any likely problems with edge strength and hot hardness, as well as potential swarf problems.
This it has achieved, said Walter tro manufacturingtalk.com, with an innovative insert design (integral geometries - intricate cutting edge forms and chip gulleys), insert grade and coating.
Xtra.tec Turn applies a CVD multi-layer aluminium oxide coating (WPP/WAM grades) that features Walter's Tiger.tec two-colour finish.
To ensure stability of double-sided indexable inserts having integral geometries, Walter said it has applied its highly successful Rigid Top Clamping system to Xtra.tec Turn's smaller (than usual) location faces around the centre hole without compromising the seating base for inserts onto their shims.
The 'mirror shim' features the underside of the insert with its integral geometry form is located onto a mirror image shim to ensure a minimum of 60% contact between the two mating faces.
This has provided the ultimate in insert stability, claimed Walterrr.
The insert fits both the Xtra.tec Turn toolholder with screw clamping and standard ISO holders with lever-type clamping.
