THE EXPERT COMPLETE PROVIDER FOR THE MACHINING Requirements in the finishing of gear components are extremely complex. High-precision finishing is performed on the bore, the external diameter of shaft parts and, if necessary, on the gear teeth, end faces and other functional surfaces. Grinding as a manufacturing step is paramount due to its efficiency in the finishing process. Conventional abrasives and superabrasives are used. their components are constantly on the rise. Lower noise level, improved running smoothness, higher torque and generally with limits on the structural size and...

Hard fine finishing is decisive in the rea- lization of the optimum tooth geometry and surface quality, with gear grinding and gear honing having now become the most important machining processes for this application. The tools make up a large share of the costs in gear grinding, power honing and structure honing. Significant potential for cost savings can be realized through optimization of these tools. As market leader in tools for hard fine finishing, TYROLIT offers a wide range of Overview of the processes and the availability of MIRA gear tools gear grinding generating grinding MIRA...

MIRA GRINDING WHEELS FOR CONTINUOUS GENERATING GRINDING Profiled grinding wheels are used for continuous generating grinding. The involute shape of the gear is created by grinding off the gear rack shaped profile of the profiled grinding wheel and the workpiece. TYROLIT MIRA grinding wheels for gear flank grinding enable low thermal loads on the workpiece while also achieving maximum profile stability, increased dressing cycles and shorter grinding times. The abrasives used cover the range of special fused and sintered aluminum oxides. TYROLIT offers you optimized specifications for grain...

MIR A DIAMOND DRESSING WHEELS FOR DRESSING IN CONTINUOUS GENERATING GRINDING The conditioning or dressing of the cylindrical grinding wheel is a selective profiling, in other words, setting of the macro geometry. In addition, the micro geometry is also set with the dressing process. This has a very significant influence on the grinding properties of the profiled grinding wheel. The grin- ding wheel is also cleaned and chips are removed from the Schematic diagram of dressing in functional area. continuous generating grinding A profiled grinding wheel is profiled using rotary dressing tools....

MIRA SINGLE PROFILE WHEELS FOR GEAR FLANK GRINDING MIRA single profile wheels are used for discontinuous profile grinding. The grinding wheel is shaped according to the gear profile of the workpiece so that the gear profile is generated on the workpiece through direct reproduction of the grinding wheel profile. Schematic diagram of discontinuous profile grinding MIRA single profile wheels are also used for discontinuous generating grinding. The gear profile is created by grinding the grinding wheel profile on to the workpiece. In addition, one can differentiate between single or double...

FOR GRINDING OF SRIRAL BEVEL GEARS A spiral bevel gear set consists of a spiral ring crown gear and a spiral bevel gear. Using gear grinding to hard fine finish these gear sets results in signi- ficantly improved gear qualities com- pared with the frequently used lapping process. The grinding is carried out using cup wheels and the generating grinding process. Spiral bevel gear set Schematic diagram of grinding wheel TYROLIT MIRA bevel gears guarantee maximum profile retention for spiral bevel gear grinding, with increased dressing cycles, shortened grinding times and a low thermal load on...

MIRA HONING RINGS FOR GEAR FLANK HONING The contact kinematics during gear honing occurs by rolling off the workpiece and honing ring at an axis crossing angle. The resulting relative motion causes the creation of curved machining tracks that do not run parallel to the flank. The surface created can lead to significantly reduced noise levels of the gear. Schematic diagram of honing with internally and externally profiled honing rings Power honing leads to sufficient stock removal rates, making pre-grinding unnecessary. In traditional structure honing, on the other hand, pre-grinding is...

MIRA DIAMOND DRESSING GEARS FOR DRESSING OF HONING RINGS AND PROFILED GRINDING WHEELS Dressing of the honing rings entails precise profiling and edging. Diamond dressing wheels with gear profiles corresponding to that of the workpiece are used. TYROLIT MIRA diamond dressing wheels are synonymous with optimum dressing results, best gear qualities and long life. MIRA diamond dressing wheels are used for the dressing of internally and externally geared honing rings, for dressing globoid wheels on Reishauer RZP/RZF machines and for dressing profiled grinding wheels in continuous generating...

EXTERNAL AND INTERNAL CYLINDRICAL GRINDING OF GEAR COMPONENTS CSS Ultra grinding wheels With the product line CSS Ultra, TYROLIT has succeeded in making a lasting impact on the micro architecture of the grinding wheel through the use of new, highquality components and innovative sinter technology. As a result, the abrasive grain can be subjected to significantly higher loads before finally fracturing. These improvements are demonstrated in practice during external cylindrical grinding of gear components with CSS Ultra through maximum profile retention with minimum wear. Electroplated CBN...
