QK1327 High Quality Heavy Duty Electric Pipe Threading CNC Lathe Machine For Large-size Hole Pipe Casting

Photos of Mahine


The digitally-control pipe threading lathe,a special tool to turn and mill pipe threads,characterized by larger diameter of the spindle bore(over 130mm in general) and chucks installed before and behind the head stock so as to hold and process tubular or rod pieces of latge diameters. In addition to milling cylindrical/conical SI/BS pipe threads,it can be used to replace the general lathes to mill outer diameters,bore holes,and planes.It is widely used to process working pieces such as drilling pipes/collars and casing in the sectors such as petroleum,smelting,chemistry,hydropower and geologic exploration.

We use electric furnace smelting, resin sand molding casting technology,avoid sand holes, stoma casting internal defect effectively, all the accessories are assayed by imported spectrum analyzer, it assures the quality of the casting . The casting had been through second thermal aging treatment with good stability.
we can can absolutely ensure the casting quality after the United States imported equipment precision spectrometer analysis.
The bed of floor type is the whole structure. The rigidity and width of guide way on the bed of lathe is good enough. The guide way is through high-frequency quenching, the slide guide way joint SD compound soft belt. to make more wear-resisting and lower friction factor. The lead screw is the whole structure (not butt). The saddle is wider and thicker than before, the machine is running more stable. And the cutting ability is better.
With the super audio quenching treatment ,the hardness of Body guide rail can reach above HRC55 degrees, it can keep the hardness high accurate, and prolong the wear resistance and service life. 
The 3 boxes of lathe were processed by Taiwan’s CNC boring and milling machine center. The other tools are processed by CNC lathe and machine center to ensure the precision of the box and tools.
The lathe bed we produced is all research and development by our own engineers. These all can greatly increased the rigidity and are helpful to widen and Thicken the dragging plate,
The large plate guide guide rail (X) is also go through the super audio quenching treatment, so it increased hardness and then could guarantee the service life of equipment more efficiently.
The equipment will firstly tested by the laser interferometer imported from Britain to test repeated positioning accuracy of X, Z direction in order to make sure the accuracy. Then the whole machine will be tested according to the National standard whole machine. 
Our enterprise have got the ISO9001-2008 quality system certification and the European Union CE certification.
The advantages of the product itself are as follows
1) Using electric furnace smelting and resin sand sculpting casting technology to effectively avoid defects such as sand holes and air holes in the castings. The ingredients are analyzed by imported spectrum analyzer to ensure the quality of the castings. The castings are treated with secondary thermal aging and have good stability.
2) It adopts an overall floor type bed with wide bed rails and good rigidity. The guide rails are subjected to high frequency quenching. The SD guide rails have SD composite soft tapes that are wear resistant and reduce the friction coefficient. The screw is integral (non-docking). The saddle is widened and thickened, the operation is more stable, and the cutting ability is improved.
3) The three boxes of the machine tool are precisely machined by the CNC boring and milling machining center imported from Taiwan. The machining of other workpieces is completed by the CNC machine tool and the machining center, which effectively ensures the accuracy of the box and the workpiece.
4) The accuracy test of the equipment is firstly conducted by a Renishaw laser interferometer imported from the United Kingdom to detect the repeated positioning accuracy of the X and Z directions of the equipment. Finally, the overall inspection and acceptance of the equipment in accordance with the corporate standard is performed, which effectively ensures the accuracy of the machine tool.
