Bronze advances for the small stuff

AC1030U is the latest turning insert development from Sumitomo Electric Hardmetal targeted at high precision small workpiece machining that covers a wide range of material types where improved levels of surface finish are required.

This is achieved by embracing a special high precision grind to the cutting edge and the incorporation of Sumitomo’s Absotech Bronze multi-layer coating, which not only helps resist micro-chipping problems but contributes to extended levels of consistent production.

The new turning insert grade combination of Absotech Bronze physical deposition coating (PVD) and Sumitomo’s latest precision ground FYS, a narrow breaker width G-class chipbreaker development to aid chip control, helps to ensure a stable operational strategy.

AC1030U inserts can be used for both turning and grooving of smaller inner diameter bores on workpieces produced from alloy, stainless and heat resistant steels, pure iron, mild steels as well as non-ferrous materials where chip control is difficult to manage.

The advanced Absotech Bronze technology comprises five alternate layers of TiAlSiN and AlTiSiN coatings which are applied to a special tough carbide substrate that has double the fracture resistance of more conventional substrates.

The coating has excellent heat and oxidation resistance with high orders of adhesion strength and resistance to peeling-off as it has improved boundary control between the coating and the carbide substrate.

Inserts are available in triangular negative plus GNDS grooving types with cutting widths of 1.5, 2 and 3mm. Positive inserts range across 80°, 55° and 35° diamond, as well as square, triangular and trigon types. All inserts have a selection of different nose radii available.

Sumitomo’s AC1030U turning insert is targeted towards high precision small workpiece machining where high orders of surface finish are required.
