A new assortment of Pramet LNEX 12 negative tangential inserts, with four cutting edges, provides a productive solution for a wide range of applications, Dormer Pramet reported.
The LNEX 12 is a robust insert designed for shoulder milling with a maximum depth of cut up to 10 mm. It features a positive rake angle and narrow T-land to provide a smooth cutting action with lower demands on spindle torque.
The peripherally ground insert offers improved wall accuracy and straightness and creates a true 90° corner. The LNEX12 also features a patented U-groove segment on all four cutting edges, which provides a good surface finish and expands its application range to low-power machines and small depths of cut. In addition, the two-sided design supports performance by making ramping possible.
The insert comes in two different geometries, F- for machining of various workpiece materials in light and medium applications, while M- is suited for medium to semi-roughing in steels and cast irons.
Also available is a line of matched cutters. The Pramet SLN12X series is available in cylindrical, Weldon and shell styles, all featuring internal coolant systems for improved surface quality.
The improved body strength and thick core offers enhanced rigidity, providing a reliable cutting process with low vibrations and long tool life for both the insert and cutter, according to the company. Easily accessible large clamping screws provide simple indexing and handling of inserts.
"The combination of the Pramet LNEX 12 inserts and the SLN12X cutters give operators a smooth cut with a clean finish, reducing the need for additional operations, such as deburring," said a company spokesperson.
