Features of Sumi-Grip

This figure shows a computer generatedcomparison of the distortion of steel andcarbide holders caused by cutting forces.

The reduced distortion of the carbide holdermakes cutting under harsher conditions andhigher feeds possible.

Low VibrationThe figure shows the measurement ofcutting vibration.At high speeds the carbide holderexperiences for less vibrations than does thesteel holder. Thus, the overhang length canbe extended and cutting speed can beincreased with the Sumi Grip´s carbideholder.

ThreadingHolders

Sumitomo Electric has developed "TME" external threadinginserts with pitch ranges of 1,0 ~ 3,0 mm or 10 ~ 24threads/ inch and "TMI" internal threading inserts with a pitchrange of 1,0 ~ 3,0 mm.

The superior features of the new sintered threading insertsinclude an M-class tolerance and dimple shaped chip breaker.The M-class tolerance reduces insert cost by eliminating theneed for expensive grinding.

Furthermore, chip control is greatly improved as a result of thespecially designed dimple chip breakers.

AC225The AC225 is a carbide insertwith a 2 μm multiple-layercoating. This design results inimproved toughness andadhesion resistance making thisgrade suitable for stainlesssteel and general steel.

T130AThe T130A is a cermet grade containing high TiN with auniform fine-grain microstructure which results in improvedwear resistance and toughness. Thus, the T130A produces a goods surface finish.

A positive rake angle encourages good chipcontrol and reduces cutting resistance.

Two tier dimple-style chip breakers evacuatechip smoothly and easily.

M-class tolerance reduces insert cost.

Four available grades cover a wider range ofapplications.
