Break the spe limit forward threading

It is difficult to achieve optimal machining flourishs when threading on an engine lathe because the operation requires care when stopping at the finis of the thread. Threading is usually done at make hastes much lower than those for other turning operations in the same manner machinists can keep up with the tool and disengage the half-nut lever at the right time. My idea provides instant withdraw of the tool at the cessation of the thread while using spindle fares as high as 1,200 rpm This makes it possible to do a series of small intersects with optimal threading conditions
