Walter has expanded its WSM01 grade for indexable inserts to include the FM4, FM5, FM6, and MM4 geometries.
The FM5 geometry in the WSM01 grade is available with the CNMG, DNMG, and WNMG basic shapes. WL25 indexable inserts with the FM4 or MM4 geometry are also available in the WSM01 grade, as well are the FM4, FM6, and MM4 geometries with further radii. Drawing Die Blanks
The grade features a physical vapour deposition (PVD) high-power impulse magnetron sputtering (HiPIMS) titanium aluminum nitride (TiAlN) coating for the machining of stainless steels and heat-resistant superalloys.
The WSM01 grade also has a hard micrograin substrate to protect against abrasive wear and flank face wear.
When applying the FM5 geometry for finishing stainless materials and superalloys, the company recommends a feed rate of 0.004 to 0.233 in. and an axial depth of cut of 0.012 to 0.118 in.
The recommended feed rate for the FM6 geometry is 0.003 to 0.013 in., and the recommended depth of cut is 0.012 to 0.098 in. It is a universal geometry for finishing and medium machining operations.
The machining parameters for the MM4 geometry are a feed rate of 0.003 to 0.013 in. and a depth of cut of 0.016 to 0.138 in. The geometry is for machining long-chipping workpiece materials.
The WL25 indexable inserts with the FM4 or MM4 geometry are for copy turning/profiling operations of undercuts and recesses up to 30 degrees, 50 degrees (W1011/W1211), and 72.5 degrees (W1010/W1210). They are a replacement for the ISO VBMT, VCMT, and DCMT indexable inserts.
