Metal lathe big bore cnc lathe machine for oil pipe processing

Metal lathe big bore cnc lathe machine for oil pipe processing thread turning machining. Its feature is that the spindle bore is relatively large (usually 130 mm or more), and the spindle box has chucks before and after, in order to facilitate the clamping and processing of large-diameter pipes and rods. Can turn metric, imperial cylindrical, tapered pipe thread, can also be used to replace outer lathes, boring holes, internal and external taper surfaces, and planes, etc. in lathes. The lathes are widely used in the petroleum sector, the gold manufacturing department, chemical industry, hydropower, and geological exploration. Other departments deal with the machining of drill pipes, drill boats, and casings.What is DRC's Pipe Threading Lathe?

QK series CNC Pipe threading lathe machine is mainly designed to process all kinds of internal and external pipe threads including metric,inch,module,DP and taper threads,as well as having all the common functions of normal CNC lathe such as processing the inner bore and end face of shafts and disks.
This series lathe machine is widely used in industries including petroleum exploiting,coal and minerals mining,chemical piping and geological prospecting,it is high-efficiency equipment in processing and repairing drilling pipe,drilling rod,thread coupling and so on.

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.

Main Characters:
Hollow spindle bore design allows processing extra-long work-piece
Double chuck equipment realizing better clamping of work-piece
Taper guide bar installed ensures taper thread processing ability

Pipe Threading Lathe Feature
1. We set up TRB (tapered rolling bearings) on this lathe to increase the rigidity of the spindle. 
2. Big spindle bore and double chuck allows clamp and process big diameter pipes;The spindle bore is very large and set up double chucks both front and back and you can choose electric chucks as you like.
3. Ultrasonic frequency quenched guide-ways are hard enough for good wear-resistance;Carriage and guide way contact surface pasted with Turcite B to maintain long-term accuracy,The slide rail f saddle is treated by wear-resisting layer coated, to avoid the crawling.
4. The slide rail f saddle is treated by wear-resisting layer coated, to avoid the crawling.
5. There are two types of speed change: Manual and step less.
6. Set up self lubrication system, and easy to maintain.
7.Integral machine bed adopts high strength iron to relize high rigidity and precision

What Is The Details Of SANZHENG's Pipe Threading Lathe?

1.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.

2.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.

3.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.

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.

that you can make the extra large spindle bore according to the customers’ requirements, and it can reach to Φ190mm at most. It can be used in the machining of the oil pipeline, plumbing pipe, and natural gas pipe and all the big pipe diameter material. It can realize all kinds of automatic cutting of many products, such as excircle, head face, inner bore, groove, cone and sphere and all the inch screw thread. The whole process is controlled by the microcomputer which can send and receive all kinds of signals and has the function of S/T/M. The appearance is beautiful and there are wide functions and easy to operate.

Pipe Threading Lathe MAIN FEATURES:
Big diameter of spindle bore, and the customer can choose the size of the spindle bore to fulfill the requirements of cutting the pipe fitting of big diameter.
The foundation of the bed is very wide and the guide rail has proper structure and the head stock has a structure of heat dissipation to improve the stability of the machine tool and the spindle more effectively.
Both the front and back bearings of the machine tool adopt the high precision angular Contact Ball Bearings, which are stable and can load more weight when they are working. 
The guide rail is made from resistant cast iron, and treated by the super audio quenching, which can guarantee the precision and the longevity of the machine.
X axis adopts 4 points a line structure and Z axis adopts 3 points a line design structure, to ensure the stability of the machine.
Z axis is designed full closed to protect the guide rail while it is working.
