Description
Technical field
The present invention relates to a kind of principal shaft locking structure.
Background technology
Along with Aero-Space (aluminium alloy, titanium alloy), automobile, precision die (graphite electrode,
Red copper electrode), heavy industry (heavy castings, steel part), 3C (aluminium alloy, plastics) etc. represent
Property industry is to working (machining) efficiency (processing cost) and the requirement of machining accuracy, with turning-milling complex processing
Center is the multi-shaft interlocked lathe of representative, because of can complete in single clamping car, milling, brill, boring,
The working procedures such as tapping, obtain tremendous development in recent years, and the appearing as of turn-milling complex machining center carries
Machining accuracy and efficiency for part provide a kind of effective solution.Relatively with conventional car
