Embodiment Construction
[0041] The present invention is a kind of live shaft excavation turning method, comprises the following steps:
[0042] (1) Clamp a workpiece on the front end of the spindle of an ultra-precision CNC lathe, and use a vacuum suction cup or a special fixture for clamping. The movement of the ultra-precision CNC lathe includes: the rotary motion of the spindle, X Lateral feed movement of the shaft slide and Z Longitudinal feed movement of the shaft slide;
[0043] (2) Install a live shaft driving and turning device on the X shaft slide or Z On the shaft slide, the driving signals of the two living shafts of the living shaft digging and turning device are actively controlled to synchronously form the fast reciprocating motion of the tool required for free-form surface turning and the fast cutting speed of the tool required for cutting difficult-to-machine materials. Excavation cutting movement.
[0044] The living shaft tunneling and turning method of the present invention is ...
