How do you define efficiency in production? What challenges are you facing as a result of changes in materials? Are you fully exploiting the potential of optimized tool logistics? LMT TOOLS combines the expertise of leading specialists and delivers tool solutions that will enable you to achieve sustainable competitive advantages.
INNOVATIONS FOR GEAR WHEEL PRODUCTION
Without gear wheels, drive equipment would almost stop turning. Manufacturers produce these components by the million for use in automotive gearboxes or in the gears of large wind turbines. Gear hobs have proven themselves for more than a hundred years now in the manufacture of gear wheels and other tooth-cutting tasks. And LMT FETTE, as a tooth-cutting specialist, has pushed forward the development and production of these and other tooth-cutting tools for nearly as long.
“THE COMBINATION OF CUTTING MATERIAL AND COATING IS DECISIVE”
Hobbing is one of the key processes in gearwheel production. Performance News spoke with Professor Bernhard Karpuschewski, Managing Director of the Institute of Manufacturing Technology and Quality Management (IFQ) at Otto von Guericke University in Magdeburg, about the requirements for the best gear-cutting tools and the future of gearwheels in the coming age of electromobility.
THE NEW NANOTHERM COATING: PERFORMANCE EXPLOSION FOR INVOLUTE GEAR CUTTERS
Tools are exposed to extreme thermal and mechanical stresses in many fields of application. Involute gear cutting provides a good example: the macro and micro geometries of the cutting edge are critical for a tool’s performance in dry machining and when the cutting process is sharply interrupted.
SPECIAL TOOLS FOR ALL TOOTH-CUTTING TASKS
In addition to the standard range of tools, LMT FETTE develops and makes special tools and gear hubs for an extremely wide range of tooth-cutting applications. The use to which the tool is put always of course takes centre stage – decisions about the shape, dimensions, degree of precision and material are made jointly with the customer. The tool can, however, also be made according to existing design drawings.
GEAR HOB: NEW GENERATION WITH PERFORMANCE BOOST
Gear hobbing is, above all, enormously flexible. As the cutters turn, any number of teeth with highly varied profiles and helical angles can be generated. With their innovative coatings, a Fette gear hob guarantees more than just longer tool live and shorter fabrication times. A gear hob with the new Nanosphere coating layer can be repeatedly reapplied – to the original quality.
"SPEEDCORE IS ALREADY AN INDUSTRY STANDARD"
Over 250 experts attended the GETPRO Congress in Würzburg at the beginning of March to talk about developments in gearbox production. It was the sixth time such discussions have been held within this framework. Experts from LMT TOOLS were also present and we spoke with Thomas Falk, Head of the Gear Cutting Segment at LMT, about the latest trends in gearbox manufacturing.
HIGHER PRODUCTIVITY THROUGH COMPLETE MACHINING
The length of the respective processing time per machine has become an established yardstick for the performance of manufacturing processes with regard to costs. It is generally accepted that the shorter the primary processing time, the more efficient the process.
LMT TOOLS FOR LARGE GEARS: HIGHEST QUALITY MACHINING GUARANTEED
The market for large gear wheels is growing – in a great variety of industries: wind turbines, construction vehicles and ships need transmission systems that use large gear wheels to move very large masses. The gearing experts at LMT FETTE know exactly what kind of challenge is involved in producing these components. LMT gear cutters and hobs offer considerable advantages also and especially in demanding finishing applications.
