LNEX 12: A robust insert designed for shoulder milling

July 3, 2023 5:57 pm

A new assortment of Pramet LNEX 12 negative tangential inserts with four cutting edges provides a highly productive solution for various applications. 

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, providing a good surface finish and expanding 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 geometries, F for machining various workpiece materials in light and medium applications. At the same time, M is suited for medium to semi-roughing in steels and cast irons. 

Alongside the new insert is a line of perfectly matched cutters. The Pramet SLN12X series is available in Cylindrical, Weldon and Shell, featuring internal coolant systems for improved surface quality. Its improved body strength and thick core offer enhanced rigidity, giving the insert and cutter a reliable cutting process with low vibrations and long tool life. 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.
