Walter USA's MU5 Insert Benefits Low-Volume, High-Mix Turning Applications

The MU5 double-sided indexable insert from Walter USA can be used for turning steel forged parts as well as stainless materials. With forged parts, particularly in automotive production, the MU5 geometry is said to minimize crater wear for more reliable automated production. Universal usability in steel and stainless materials is said to be advantageous for work involving changing material demands and smaller batch sizes. According to the company, the insert owes its versatility to its positive macrogeometry and negative clearance.

Other features include an open chipbreaker groove for long tool life and soft cutting features; a V-shaped chipbreaker for improved chip breakage; and a curved cutting edge that is said to improve surface finish quality.

For copy turning, the MU5 geometry is said to improve chip breakage not only for turning and facing, but also for chamfers or radii that would otherwise be critical.

Recommended machining parameters for most applications are 0.0006" to 0.024" feed per tooth and 0.020" to 0.160" depth of cut.
