Admittedly, the future of the manual gearbox is uncertain given the success of e-mobility and many automatic models. However, millions of cars are still equipped with this solution. What distinguishes the technology in detail?
The HLC 150 H horizontal gear cutting machine by EMAG KOEPFER is the perfect complete solution for machining workpieces up to module 3 with a maximum length of 500 mm (20 in). It not only features all relevant gear cutting technologies such as gear hobbing, skiving, screw milling and worm skiving, it also includes press deburring and chamfering integrated into the machining area. As a result, an extremely wide range of workpieces can be finished without burrs – including gear and anchor shafts, steering pinions, planetary gears and worm gears.
Maximum flexibility is required for gear production. EPS steering is a good example: Production planners for this application are looking for machines that can efficiently and completely cut an EPS steering gear including steering pinion, worm gears, and screws. The HLC 150 H horizontal gear cutting machine from EMAG KOEPFER is the perfect solution for this.
The VLC 200 GT is loaded at by the integrated pick-up spindle. The process starts with hard pre-turning of the shoulder and the bore hole in quick succession. Only a few micrometers of material are then left to be removed from the automotive gear by the subsequent grinding process, using either aluminum oxide or CBN grinding wheels.
Transmission manufacturing is among the most innovative areas of passenger vehicle production: This central component has to ensure a high level of driving dynamics, while keeping fuel consumption low at the same time. Transmissions are therefore becoming smaller and lighter, and provide a higher number of speeds. The individual gearwheels are a main focus of the developers. Their production in extremely high volumes requires a high level of efficiency—at high precision, high speed, and highly controlled.
