Introduction
QKA-series CNC pipe thread lathes were developed mainly for the turning of oil-field pipe threads. But now they are also used to the turning of pipe threads of various kinds, e. G. Cylindrical and conical threads, threads connected continuously one another, and end-face threads as well, and they can also be used as universal CNC lathes for the turning of circumgyration bodies of various curving generatrices. 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 ate ideal medium-type mechanical machining equipment.

Structure
Bed with high rigidity for the sturdy body and widened guide-ways, and with long life and high precision retentiveness for the twice aging, hardening, and grinding.
Headstock strong enough to support the heavy cutting and finish turning for the sturdy structure, quenched and ground gears, large spindle, and precision heavy-duty bearings.
Centralized auto lubrication.
Guide ways with TSF coated make the friction reduced and the servo performance promoted.
Chuck arrangement both at front end and rear end secures the stability and reliability.
