LMT’s universal face milling cutters

In a recent trial involving face milling the joint faces of dies, at 180 m/min, removing 60 cm³ of stock material a minute, tool life was increased by 25 per cent and the number of cutting inserts normally required for the job was halved. The combination of a MultiEdge Double 8 cutter body and insert can be used for roughing and finishing, steel and cast iron, with the availability of two insert sizes, 12.7 mm and 16 mm. The diameters of the monoblock cutter bodies range from 32 mm to 160 mm with between 3 and 19 insert pockets, according to the size of the body. Inserts are available in carbide grades LC225T and LC240T for steel, and LC610T for cast iron. LC225T is a high wear resistant grade, with high orders of toughness for wet and dry milling at high cutting speeds. using low to medium depths of cut and chip loading. The LC240T grade is more suitable when medium to high cutting speeds and chip loading, is required. The LC610T cast iron grade is highly wear resistant, maintaining high levels of edge stability under conditions when high cutting speeds with low to medium depths of cut, and chip loading are required. It can also be used for fine finishing high strength and non-ferrous materials.
