The Advantages and Technical Requirements of CNC Pipe Thread Lathe

Goto HAVEN to know more.

CNC pipe thread lathe is a professional machine tool for pipe processing. It is professionally designed and manufactured for the processing requirements of oil pipelines, casings, and drill pipes in the petroleum, chemical, and metallurgical industries. It is mainly used to process inner and outer pipe threads. The CNC system automatically controls, It can accurately process all kinds of internal and external threads, and can also be used as an ordinary CNC lathe to process the external and internal holes, end faces and conical surfaces of the workpiece.

Advantages of CNC pipe thread lathe

1. The machine has the characteristics of a high degree of automation, good efficiency and high precision, wide application range, simple operation, etc.
2. CNC pipe thread lathe is my most common lathe at present, and it is a fine product among the medium-sized CNC lathes.
3. Headstock is driven by a variable frequency motor and is continuously variable. Spindle bearings of well-known domestic manufacturers, three-jaw chucks of well-known domestic brands.
4. And the modular design of the CNC system is easy to debug and convenient to maintain. The x and z axes use high power, servo motors, advanced performance, and strong reliability.
5. CNC pipe thread lathe adopts a cast bed saddle. The slide plate has a reasonable internal rib layout. The high-precision ball screw produced by Jining is selected for high precision and accurate transmission. The well-known domestic brand four-station electric tool holder has high positioning accuracy, strong rigidity, and high reliability.

Technical requirements of CNC pipe thread lathe

1. Satisfy various regulations related to equipment quality management such as machine repair equipment.
2. The structure and production of the lathe should meet the relevant national and industry standards, and all the attachments of the attachment and the body are provided by the manufacturer.
3. The operating conditions of the lathe must be adapted to the objective environment in which the equipment operates, and should meet the relevant industry standards and various requirements.
4. Provide lathe parameter information, product identification certificate, product model use certificate, technical data sheet and related technical information, and successful supply records of similar products.
5. This technical condition is the minimum technical requirement, and it does not make provisions for all technical details, nor does it fully quote the relevant standards and regulations. The contractor shall provide products that meet this technical condition and national standards and industry standards.
6. After winning the bid, the CNC pipe thread lathe will provide equipment basic drawings, equipment installation drawings and instructions for use. The general assembly drawings, appearance drawings, nameplate parameters, instructions, product qualification certificates, quality inspection reports, random spare parts lists and other relevant materials shall be provided upon delivery.

There are several posts here on the subject, mostly for turning tapered pipe threads. Turn your threading tool upside down, reverse the spindle, and thread away from the chuck (assuming the big end of the thread is on the left). Work out in advance how much you need to feed the cross slide per revolution of the chuck.

Threading away from the chuck and turning the cross slide in gives three strong advantages. You can't run into the chuck because you were busy looking at other things. The backlash is always taken up. If you get confused, just stop turning the cross slide as you are moving away from the material, not into it.

With little practice this works well with the 1:16 pipe taper. I think you are wanting a much steeper taper, so it may be slightly more challenging.

Another method is offsetting the tailstock.
