PTQKA340 CNC PIPE THREADING LATHE

    

These lathes were developed mainly for the truning of oil-field pipe threads. They are suitatle ofr the turning of various kinds of pipe threads, andare also can be used as universal CNC lathes.

        These CNC pipe thread lathes are controlled by semi-closed circle controlling systems. They are suitable for the turning of circumgyration bodies of various curving generatrixes, the turning distinguishability is 0.001mm.They can be used to the turning of cylindrical and conical threads, and threads connected continuously by them, and end-face threads as well, They have functions of automatic tool compensation, rough-turned piece circle, thread-cuttig circle, slotting circle, and absolute zero can be set at your will. These machines are suitable for varified workpieces machining in medium and small batches, and are of good flexibility, high efficiency, finishing up with good conformity, and are easy to program, simple to operate. So they are ideal medium-type mechanical machining equipment.
