The Widia M 780 face milling cutter is fitted with square, negative indexable inserts with eight cutting edges. According to the company, its positive cutting angle promotes a smooth cut, low cutting force and low power consumption. The four coated grades TN2510 (for machining GTS and GTW cast iron); TN5515 (for GGG with low/average hardness as high as GGG50, as well as GG and GGV); TN7525 (for GGG increased/high hardness from GGG50 and steel); and TN450 (for GGG increased/high hardness from GGG50 and steel) are available with three geometries—LD, GP, HE—for light, general and moderately heavy milling.

 

Offered in left- and right-hand versions, the cutters can also be used with a coolant screw. The wedge clamping system is used on both coarse and fine pitch options.

Can Additive Manufacturing Increase Milling Feed Rates?

With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
