M6 MOVIE


M6 Chipbreaker – Features & Benefits

Strong, double-sided chipbreaker Intended for semi-roughing and roughing of steel A well-balanced design combining excellent chip control and relatively low

cutting forces which provides reliable cutting action in both continuous as well as interrupted cuts

Well suited also for machining of ferritic and martensitic stainless steels and ductile cast iron

M6 Chipbreaker – Features And Benefits

Negative double-sided chipbreaker Wide positive protection chamfer High positive rake Wide chip groove High edge strength Strong cutting edge attributes

Better chip control & efficient chip

evacuation Lower cutting forces & low energy

consumption Dependable strong edges & high

resistance against chipping Reliable wear behaviour (both

crater and flank wear) Result: Optimal tool life, excellent productivity and versatility

M6 Chipbreaker – Application Area And Range

6

In general steel applications From SMG P1 to SMG P11 ap=1.0-8.0 mm f=0.20-0.80 mm/rev

Steel machining Main application area is steel machining. The more reliable & smooth cutting action improves tool life and chip evacuation on a wide range of steel turning operations even at higher feed rates and intermittence. M6 Wiper Allows even higher feed rates for productivity or superior part quality with better surface finishes eliminating the need for finishing operations in many applications.

“wide working window of M6”


M6 Chipbreaker – Application Area And Range Stainless steel machining M6 with Duratomic® grades makes it possible to machine stainless steels M6 in TP2501/ TP3500 are alternatives in ferritic and martenistic stainless

steels for intermittent cuts as well as mixed production productivity in austinitic stainless

Cast iron machining M6 in Duratomic TK2001 improves reliability and tool life for ductile cast irons

and other challenging cast irons M6 in Duratomic TP0501 improves toughness in difficult grey cast irons while

M6 in Duratomic TP1501 provides a good back up in ductile cast irons machining

Duratomic grades Duratomic grades enhance productivity and life time of the cutting edges with

M6 geometry M6 is available in several Duratomic grades, including TP0501, TP1501,

TP2501 and TP3500 for steel operations Seco chipbreaker M5 and MR7 Overlaps with the “wide working window” of M6 with comfortable spread on

MR7 vs M6

Choose MR7 when Rough forgings/castings of steel, cast iron, stainless

steel with difficult skin and oxide scale Complex parts with heavy interruptions with large

depth of cuts and high feed rates

M

Working area where MR7 has its strength in combination with heavy interruptions or harsh oxide scale MR7 M6

M5 vs M6

Choose M5 when Aggressive chip breaking is the priority in ductile, long-

chipping steel/stainless steel with small depths of cut and low feed rates

Typically ”near-net-shape” components of cast and forgings with D.O.C varying from moderate ap down towards zero

Field Test Experience M5 vs M6

Crater wear, chip hammering, chipping significantly more common on M5

Images to the left illustrate M5 and M6 applied using equal cutting parameters and after equal time in cut. The crater wear on the rake and the back rake is of larger magnitude on the M5 which is often experienced when comparing these chipbreakers.

M6 Conclusion

M6 can be considered a first choice Cutting forces are lower for M6 compared to M5 and MR7 M6 has generally a softer chip breaking compared to M5,

but harder chip breaking than MR7

M6 gives lower noice levels than M5 and MR7 M6 reduces chipping, plastic deformation and crater compared to M5 M6 provides longer tool life compared to M5 and MR7

M6 is closer to M5 than MR7 (edge strength and working window)
