1. BRIEF INTRODUCTION QKA1212/1219/1235 CNC lathes were developed mainly for the turning of oil-pipe threads. They are suitable for the turning of various kinds of pipe threads, and are also can be as universal CNC lathes. These CNC pipe thread lathes are controlled by semi-closed circle controlling systems. They are suitable for the turning of circum gyration bodies of various curving generatrixes, the turning distinguish ability 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-cutting circle, slotting circle, and absolute zero can be set at your will. These machines are suitable for verified work pieces` 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 machine equipment 2. Machine attachment 3-jaw chuck (manual operation) QKA1212 QKA1219 QKA1235 380MM 500MM 780MM Operating and repairing tools 1 set 3.
