Complete Dry Machining of Complex Aluminum Components in the Production of Automobile Units

摘要

Automobile components made of aluminum alloys can be machined using extremely small quantities of lubricant (micro lubrication). Whereas milling operations can be carried out totally without lubricant, the targeted supply of lubricating medium is required when drilling, reboring, reaming, screw-cutting and also deep drilling. In addition, a tool design which is completely "dry-machining-compatible" is necessary ahead of work, and the machine interior must be designed in such a way that the produced chips can be removed without the rinsing effect of cooling lubricant. Initial investigations on different machining centers have verified that production with precision machining tools, the basis for complete machining of cubic aluminum components, is possible today with process safety and reliability using micro lubrication.
