Sumitomo Electric Hartmetall Small-batch operations
UK – Ideal to gain the advantage of using the latest developments in cermet inserts for precision turning technology of longer tool life, excellent wear resistance and superior consistency of size and surface finish when compared with tungsten carbide, has led Sumitomo Electric Hardmetal to introduce two new grades T1000A and T1500A of uncoated cermet inserts, the company says. According to Sumitomo, the sharp edge inserts create a greater cost-effective source for smaller batch quality turning operations against the more normal and more expensive coated cermet insert. The uncoated T1000A (P10) cermet grade incorporates a dual structure for good wear resistance and toughness and is ideal for applications such as fine finish profiling and continuous high-speed cutting. The T1500A (P20) incorporates a series of 3-D chipbreaker designs that enables a stable, quality finish in interrupted cutting cycles.
