Tungaloy Corporation is adding a positive insert line to its existing FW & SW turning wiper insert range, allowing for feed rates and surface finish to dramatically improve in general turning operations.
Surface finish quality is directly influenced by feed rate and insert nose radius: the higher the feed rate, the rougher the surface generated by the edge of a given nose radius. In a conventional tactic, the feed rate is decreased to get a better surface quality. Tungaloy’s FW & SW wiper series have changed this through the effect of their uniquely developed cutting edges which allow the feed rate to be increased without deteriorating the surface finish quality. Wiper inserts allow running at up to double the recommended feed rate of a normal insert while still providing a surface quality a double that of a normal insert.
The new line of positive inserts incorporates SW chipbreakers, which will improve chip control in finishing and semi-finishing ID turning operations. This addition will complement the existing negative insert range in the FW & SW wiper series to cover wider range of applications to facilitate customers’ productivity increases.
The new positive inserts are available in T9100, a CVD grade for steel turning and NS9530, a cermet grade for thermal shock resistance, covering a great variety of workpiece materials.
