SpeedCore
The Industry Standard
Increased efficiency and flexibility are requirements of the gear industry. Still many users do not take advantage of their full machining potential. The reason: State of the art gear cutting machines allow higher cutting speeds up to 30 % which can not be utilized with conventional PM-HSS hobs. Most of the machines are already designed to use carbide hobs and work under dry conditions. With the newly developed material SpeedCore, a cutting material as a class of its own, LMT now turns realities upside down – for the benefit of the customer.
Up to 50% higher cutting speeds
Higher cutting speeds increase the mechanical and thermal load on the tool. The HSS materials are limited to a range of cutting speeds due to their lower high temperature hardness. LMT Fette’s new SpeedCore hobs are manufactured from a new cutting material with significantly increased high temperature hardness; at the same time offering sufficient toughness. With the new SpeedCore hobs the cutting speed can be increased by 30 % and more. The customer’s benefit is: significantly more parts in less time. The machines will be utilized more efficiently. No additional investment is necessary to increase the productivity, just the new SpeedCore.
Speedcore in Larger Sizes – The Success Story Continues
As SpeedCore hobs have performed very successfully in the automotive sector, the range has been extended to larger sizes. By this development hobs up to module 16 are now available. They have already passed field tests on several occasions. This includes the manufacture of a module 9 gear for a planetary gear set for the mining industry. The new SpeedCore hob with a Nanosphere 2.0 coating was competing against a TiN coated tool in EMo5Co5. The impressive result: Processing time was reduced by approx. 50 % (26.2 min vs. 50.9 min). This means that SpeedCore is now utilizing performance ranges which were previously limited to multi-part tools with carbide cutting edges. Compared to such tools the solid type design provides additional benefits such as increased accuracy, lower cost and a higher effective number of teeth.
