With its extensive range of tools, LMT Tools offers each customer the perfect solution for the respective application – even in the case of ultra-complex metal-cutting tasks. Now the precision tool specialist has extended its product portfolio of high feed cutters to include an entirely new generation of solid carbide end mills as well as supplementing its successful system of indexable inserts. Current developments have focused on consistent maximization of performance and access to new applications.
High feed cutters permit high machining volumes thereby reducing processing times and, ultimately, manufacturing costs. In particular, finishing tasks that make heavy use of milling, such as die and mold industry benefit from these qualities. The high feed range offered by LMT Tools comprises of solid carbide and indexable insert cutters with diameters of 1 to 160 mm, thereby covering nearly all applications. With its latest additions, the precision tool specialist is now extending its range of services, offering its customers one of the broadest ranges of tools on the market for high feed cutters. Efficiency and feasibility have also been optimised.
A new standard
In terms of tool life and productivity, the new solid carbide high feed cutters are setting standards in machining steel and casting (CarbFeed Steel), stainless steel and alloys, which are difficult to machine (CarbFeed Inox) as well as hardened materials (CarbFeed Hard). In pocket machining, new records have been achieved which are significantly higher than the market standard. These top performances have been achieved through optimal adjustment of macro- and micro-geometry to the tools’ corresponding area of application.
High feed rates, short processing times
End mill geometry, substrate, coating and cutting edge treatment have been specially developed for the materials to be processed and are optimally coordinated. The peeling geometry is characteristic. Thanks to the positive rake angle, the cutters cut in an essentially softer manner than their predecessors. This conserves the machine spindle and increases the tool life. The number of flutes has also been adapted, resulting in further increase of cutting performance: Thanks to four (ISO M, ISO P) or six to eight (depending on the diameter) cutters (ISO H), the new performers increase the feed rate by approx. 50% and this also has a positive influence on the tool life.
Maximum machining volumes guaranteed
The modular MultiEdge 2Feed mini cutting system which is used primarily for machining smaller and medium-sized components has also been supplemented. The tried-and-tested geometry for machining steel (ISO-P), stainless steel (ISO-M), cast iron (ISO-K) and hardened steel and cast materials (ISO-H) has been extended to include a type for machining high temperature-resistant steel and 2 super alloys (ISO-S). The positive position of the indexable inserts (WSP) leads to a softer cut which reduces the cutting forces. This guarantees maximum machining volumes – even on modern machining centers which are often less powerful.
Longer tool life and lower costs
The outstanding combination of carbide and coating guarantees a high degree of process reliability and long tool life. The standardised size of the indexable inserts (regardless of the cutter diameter) also reduces investment and storage costs. This new cutting material is also applied on the tried-and-tested indexable insert geometries: while the indexable insert with a negative protective chamfer (ER geometry) displays a particularly stable cutting edge, the geometry featuring a chipbreaker groove (SR geometry) is distinguished by a softer cut. Faster processes, high process reliability and maximum feasibility: with these new tools, LMT Tools begins a new chapter in the area of high feed cutting and extends its innovative lead even further.
