Precision machining solutions for new energy vehicle reducer gears
Quality machined gears maintain a stable gear ratio, provide a longer working life and improve transmission efficiency. New energy vehicle gears are made from hard, carburised steel and have more stringent accuracy requirements.
WSS CBN tools have a stable and efficient solution for roughing and finishing of main gears, pump wheels, drive shafts, direct drive bushings and differential ring gears. Rough machining removes the carburised layer efficiently, and finishing ensures dimensional accuracy, reducing machining costs and enhancing the product benefits of the gears.
Machining of main reduction gear end faces and bores
WSS CBN coated tools for 20CrMnTiH main reduction gears offer long tool life and high cutting efficiency. The addition of a trimmed edge avoids the problem of vibrations and improves the surface finish of the gears.
High precision machining of the bore of the pump wheel end face
The bore of the pump wheel must be kept within tight dimensional tolerances, and machining the bore of the pump wheel with a Whiskey coated tool provides longer machining life and significantly reduces out-of-roundness.
Severe interrupted cutting of bearing tooth end faces
WSS CBN coated tools can be upgraded from two cuts to one at the same time as increasing feeds, resulting in a significant increase in efficiency.
Roughing and finishing with one tool for the outer face of the direct drive tooth sleeve
WSS CNGA120408 coated CBN tools are highly efficient in removing the carburised layer from gears for rough machining and accurate in ensuring dimensional tolerances for finishing, making them the cost effective choice for highly lean machining.
Differential ring gear end face and bore machining
High hardness differential ring gears with high dimensional accuracy requirements, WSS CNGA coated tools for face roughing with high cutting efficiency, finishing turning to ensure gear accuracy, gear bore finishing to achieve high standard surface roughness.
