What is SANZHENG's Pipe Threading Lathe?

pipe thread lathe

 

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.

SANZHENG 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.

What Is The Application Field of Pipe Threading Lathe?

1. SANZHENG research and develop Pipe threading lathe for more than 50 years, and our company was restructured in the year 2002 . More than 200 staff ,9 professional engineers ,cover an area of 120,000 square meters.

2.CNC pipe threading lathe is a special model of CNC turning lathe ,mainly used in oil and gas field, machinery manufacturing, geological exploration, thread repair function and so on.

3. Customized service, we can make the pipe threading lathe according to clients’ requirements.

4. SANZHENG have our own casting workshop, guarantee good quality of the machine.

5. A big production capacity, always have machines in store, though so many orders we can also guarantee delivery time.

6. Certificate of CE and ISO

7. SANZHENG have exported to Dubai , Malaysia,the USA ,Russia, Iran etc.

8. SANZHENG make OEM for Knuth Germany about 8 year ,no quality problem , the orders are added every year.

4.First step of the accuracy test of the equipment is testing the repeat accuracy of X and Y axis with Renishaw laser interometer imported from Britain. After that, inspecting and accepting the whole equipment based on the enterprise standards, guarantee the accuracy of the machine tool.
