Abstract
A method of manufacturing a transmission case housing is provided wherein a minimum quantity of lubrication as a compressed air/oil mist is supplied as the housing is rough bored and face milled. The transmission case defines a plurality of transmission fluid drainage holes for draining transmission fluid from the transmission when installed in a vehicle. The housing is positioned with the fluid drainage holes below a central axis of the housing and a plurality of internal bores and faces are bored and face milled on the housing. The compressed air/oil mist is sprayed from the cutting head to cool and lubricate the boring and face milling tools. Machining chips are blown off the rough bored housing through the fluid drainage holes.
Claims18
A method of manufacturing a transmission housing comprising:
- positioning a cast housing with a plurality of fluid drainage holes below a central axis of the cast housing;
- boring and face milling a plurality of internal bores and a plurality of faces of the housing to form a rough machined housing;
- and
- blowing machining chips off of the rough machined housing through the fluid drainage holes.
A machining center comprising:
- a fixture holding a housing defining a plurality of drainage holes oriented below a central axis of the housing;
- a plurality of interchangeable tools boring and face milling a plurality of bores and faces of the housing;
- and
- a lubrication system lubricating and cooling the interchangeable tools with a compressed air/oil mist while boring and face milling the housing and blowing machining chips off the housing through the drainage holes.
