Tungaloy’s new positive wipers improve both feed rate and surface quality in ID turning

Tungaloy Corporation is adding an active 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 inserts 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 standard insert while still providing a surface quality a double that of a conventional 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 a 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 vast variety of workpiece materials.

Features:

Uniquely developed wiper geometry on the cutting edge enables a high feed turning with a superior surface quality.

Enhanced with the new line of positive inserts, the FW & SW wiper insert series can offer a wide selection of tooling for high efficiency and more productive machining
