Description
Technical field
The present invention relates to a kind of repacking lathes and method for the processing of non-circular curve slot, belong to lathe cutting techniques neck
Domain.
Background technique
Non-circular planar slot processing is processed using machining center substantially at present.For small processing enterprise, does not have and add
When work center or machining center quantity are unable to reach production capacity, the processing of non-circular planar slot just receives great shadow
It rings.And circular flat slot is only capable of processing using center lathe, the planar slot of non-circular profile line can not be processed, medium-sized and small enterprises are caused
Prouctiveness is unable to satisfy demand.
The planar slot of non-circular profile is irregular due to contour line, and center lathe can not be processed, and the processing of general enterprises
The production capacity at center is too small, and many research institutions are still machined out using center lathe now, and center lathe can not carry out it is non-
The processing of circular curve slot, when the planar slot on workpiece containing non-circular profile, only the research institutions of center lathe can not be carried out
Processing.
Therefore, it needs to develop a kind of lathe improved on the basis of existing lathe, realizes engine lathe processing non-circular curve
The device and method of slot.
Summary of the invention
