QLK1320B CNC pipe thread lathe

The bed is an original three-wall structure, and the rear wall is arranged with a 12° bevel, which greatly improves the rigidity of the machine. The wide dimension of the bed rails, and the supersonic quenching and precision grinding ensure the machine's accuracy and service life.
The integral gear box type spindle unit, QLK1320B is a two-speed inverter with no step in the gear; QLK1345C is a high-power spindle servo motor with full stepless speed regulation. A wide range of speed control, both to meet the requirements of thread finishing, but also to achieve efficient cutting. The application of quenched precision grinding gears and high quality bearings ensures low noise and good sound quality.
The main shaft box adopts a powerful external circulation cooling lubrication system, which not only reduces the temperature rise of the main shaft, but also effectively maintains the cleanliness and lubrication of the main shaft box.
The X and Z axes adopt high-precision ball screw direct drive and lead screw pretensioning structure. The Z axis screw nut hanger is an integral casting structure. The guide rail is affixed with YT soft tape to improve the guide accuracy and machine tool accuracy retention, and effectively increase the service life of the machine tool.
The oversized four-station numerically-controlled electric tool rest makes the machine tool more efficient and more effective in ensuring the accuracy of the precision threading of the inner hole of the precision car.
The machine tool is widely used in the petroleum industry for the processing of drill rods, joints, casings and other parts. It can also be applied to the processing of various pipe threads in the chemical, coal, and geology industries.
