Hot sale hydraulic roll threading machine,QK1335Lathe Machine for Repair of Pipe Threads on Rotary Shouldered Connections

Pipe Threading Lathe

Standard CNC system:Choose to configure the CNC system: Siemens, Fanuco,GSK

Tool holder form

Standard: 4-position electric turret;Select the configuration: 2/6/8/12 station electric knife holder

Chuck model

Standard: before and after the double three-jaw chuck

Select the configuration: before and after the double four-jaw chuck

Vertical four-position electric turret;With tailstock;Automatic lubrication system;Turning cooling system.Independent spindle, servo drives, variable speed.

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

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;

Application:

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.

Pipe Threading Lathe Machine

Application:

The application fields of Pipe Thread Lathe machine are the Processing and repairs of drill pipe, drill collar, joint, kelly bar and sleeve of Oil sector, Metallurgic Industry, Geological Prospecting, Chemical Industry & Hydropower.

Advantage:

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.

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.


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.


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.
